PRESIDENT’S MESSAGE

Building with Intention As we begin a new year with the OGSA, I would like to express my sincere gratitude to everyone who contributed to the incredible success of the 2026 OGSA Turfgrass Management Conference. Seeing 565 members come together in Collingwood was truly inspiring—an energizing start to the year and a strong reflection of the engagement, relevance, and strength of our association. The addition of the Equipment Managers Track, along with expanded opportunities to earn IPM points, created broader and more inclusive educational experiences, and the level of participation across all sessions was remarkable. We are also deeply grateful for the continued support of our industry partners, whose contributions play a vital role in enhancing the quality of education, networking, and overall conference experience for our members.

I would also like to take a moment to recognize Ian McQueen for his exceptional leadership and dedication to the OGSA serving as president over the past two years.

Ian, your steady leadership, guidance, and commitment have been instrumental in moving our association forward, and we are sincerely grateful for the vision you brought to the role.

I am thankful for the trust you have placed in me and mindful of the strong leadership that has come before. Those who previously served have built a solid foundation that has positioned our association for success and growth, supported by a dedicated and passionate office team who work tirelessly to deliver our programs, offerings, and events.

Together, this collective effort has led the OGSA to where it is today.

Our goal is to solidify what we have built, identify opportunities for improvement, and ensure long-term stability before continuing to expand.

Our association is currently experiencing a record-high membership—a milestone that speaks to the value, relevance, and strength of our organization. While this growth is encouraging, your board is committed to ensuring it is managed with intention and care. As we look ahead, we will focus on strengthening governance, refining our It is a privilege to serve as president infrastructure, and enriching the of the OGSA in 2026.

programs and services our members rely on. Our goal is to solidify what we have built, identify opportunities for improvement, and ensure longterm stability before continuing to expand. We are fortunate to have a strong, collaborative board, and together we will continue to move the OGSA forward with purpose and integrity. I encourage all members to become involved in initiatives that help elevate our profession and strengthen its future—whether through programs like First Green, contributing to the completion of BMPs, or supporting research through Rounds for Research. Each of these efforts plays an important role in supporting education, research, and awareness across our industry.

On behalf of the entire OGSA, we look forward to serving our members in 2026 and building on the momentum we have created together. I am excited for the year ahead and look forward to working alongside you as we continue to grow, evolve, and strengthen our association.

GCSAA Celebrates 100 Years OGSA donates $5000 USD to support Centennial Campaign The Ontario Golf Superintendents’ Association has generously donated $5,000 to the GCSAA Foundation, the philanthropic organization of the Golf Course Superintendents’ Association of America (GCSAA), to support the new Col. John Morley Centennial Campaign.

GCSAA will turn 100 on Sept. 13, 2026, and it has embarked on a centennial fundraising campaign to establish a new endowment honoring GCSAA’s founder, Col. John Morley, with a goal of raising $1 million to fund new and innovative initiatives for the next 100 years.

The Ontario GSA is supporting the centennial campaign at the Chapter Legacy Leader Level, which recognizes donations of $5,000 or more. With this donation, the Ontario GSA is a new member of the Foundation’s Platinum Tee Club, which recognizes organizations that donate $5,000 or more annually to the GCSAA Foundation.

“Thank you to the Ontario GSA for supporting the future of the game and the profession through its donation to the foundation’s centennial campaign,” GCSAA CEO Rhett Evans said. “The generosity shown by the Ontario GSA undoubtedly strengthens the association and, in turn, the success of this campaign. GCSAA is grateful for the support from the Ontario GSA.” “The OGSA is proud to celebrate a century of golf course superintendent leadership and innovation, standing on the shoulders of the giants who built our profession. We know the choices we make today will shape the next 100 years and it is our privilege to support this important initiative and the enduring legacy of the GCSAA.” - Kevin Collier, OGSA President, Superintendent, RiverBend Golf Community.

Canadian Golf Industry Reaches Record Participation NGCOA Canada’s 2026 Pulse Report Highlights Strong Performance and Measured Outlook March 5, 2026 - Ottawa, Ontario The National Golf Course Owners Association (NGCOA) Canada has released key findings from its 2026 Pulse Report, presented by Priswing.

The report analyzes performance across Canadian golf course operations during the 2025 season while providing an outlook for the 2026 golf season.

The findings show the Canadian golf industry continuing its strong trajectory, with participation reaching a new national record and revenues exceeding projections for the third consecutive year.

Rounds played increased 7.9% in 2025, marking the fifth increase in the past six years and pushing national participation 36.4% above 2019 levels, reinforcing that the surge in golf participation that began in 2020 has stabilized at a higher longterm baseline.

“This year’s Pulse Report confirms that golf’s growth is not a short-term trend but a structural shift in participation,” said Jordan Vizena, Managing Director of Research & Membership for NGCOA Canada.

“Operators across Canada have successfully converted increased interest in the game into sustained engagement and stronger business performance.”

Written by Andrew Marsan, Turf Technical Sales, Plant Products.

A Guiding Light Kerry Whale has always approached her work with a simple, steady mindset: “What is the worst that can happen?” It’s a question that carried her through more than three decades in the turf industry, where she turned chance encounters into lasting partnerships, navigated a traditionally male-dominated field with quiet confidence, and built a legacy defined by trust and unwavering support for those who followed. Very few in this game have left a mark as lasting as Kerry Whale.

Now retired from AllTurf Ltd., she reflects on a career defined not by headlines, but by the people she met, the problems she solved, and the doors she opened that paved the way for women in the industry. In handwritten notes shared for this profile, she offered glimpses of that journey – from her first steps in horticulture to the friendships that made the long road worthwhile. Her story is long overdue and well worth the wait.

IN THE HOT SEAT Q. FAVOURITE PIECE OF EQUIPMENT? A. Expedite - The older generation will remember this.

Q. FAVOURITE MEAL? A. Prime Rib and ice cream.

Kerry attended the University of Arizona and later transferred to the University of Waterloo, gaining experiences that shaped her approach to work and life. She first entered the industry at the age of 22, taking a summer job at a garden centre in Oakville. The role awakened a genuine passion for nurturing growth – a quality that would define her entire career. What started as a temporary position quickly turned into a longterm opportunity, and she eventually worked her way up to manager.

Her path unfolded steadily. She took a position with Nutrite as a sales representative and then spent 20 years at Plant Products, beginning in the greenhouse sector before moving to the turf division. The turf team there, led by Harold Van Gool, proved the biggest influence on her career. In turn, Kerry became a humble mentor who shared knowledge generously and fostered a true team atmosphere.

Q. FAVOURITE SONGS? A. Brown Eyed Girl, Chicken Fried, Paradise by the Dashbrown Light.

Q. FAVOURITE ICECREAM SHOP? A. Shaw’s in St. Thomas.

Q. FAVOURITE BAKERY ON THE ROAD? A. The Gingerbread House in Komoka – best raisin bread.

Q. FAVOURITE “SMART ASS” CUSTOMER? A. Hands down… Tim Webb.

Family first: Kerry alongside her sons, Jordan (35) and Andrew (31).

She was instrumental in building the Bowen, and Rhod Trainor, Plant Products baseball tournaments and division into what it is today. Her final 14 years at AllTurf allowed her to pumpkin-growing contests, outdoor pianos in Colorado, the lively continue that work, becoming a Blazing Pianos in Florida when Chris trusted resource for turf managers Dew and Keith Bartlett joined the and superintendents who stage, and Jerry Richard's "Klingon" appreciated her insight, reliability, costume in California.

Some favourites included Ian McIsaac, Scott Thompson, Scott The work brought many joyful Dyker, Robert Cowen, Bill Martel, moments: bobsledding at the CGSA and Tracy Fowler. in Calgary with Neil Acton, Ian

Kerry isn’t just a trailblazer for women in golf; she is a pillar of our industry. I’m confident that I’m not the only one who owes her a great deal of gratitude for the kindness, knowledge, and friendship she has shared. Kerry is quick to help, to smile, and to care, which has made her a fan favourite amongst customers, colleagues, and even competitors. It is truly a rare feat to be both so widely adored and respected. I owe Kerry a great deal of thanks for creating a place for me, as a woman, in the industry I love, and even more so for helping me find my place in it. -Emma McQueen, Plant Products APRIL 2026 | ONCOURSE 13

GC HIGHLIGHT | MEMBER PROFILE

These moments reveal the warmth, energy, and connection Kerry brought to everyone she worked with. For many, Kerry didn’t just build relationships. She built belonging.

Jason Harris, superintendent at Orr Lake Golf Club and a former colleague at Plant Products, echoes that sentiment: “Kerry Whale has been a mentor to me and many others throughout my career. She would be the first person to invite a non-customer to join her group at an event if she saw them by themselves.

She didn’t like just having a customer get-together without some extra fun – for those of you that remember the Plant Products Blazing Pianos event in Florida. She knew all her customers’ and coworkers’ birthdays and family events. Kerry was instrumental in creating and maintaining the team environment of the turf department.”

There really aren’t enough words I can say to express the enormous respect I have for Kerry both as a sales representative and as a human being.” That sense of inclusion and joy wasn’t accidental; it was something Kerry cultivated deliberately over decades.

Matt Hewitt, Director of Golf Course Maintenance at Deer Creek Golf Club – who has known Kerry since his first steps in the industry – adds, “Kerry is a legend. She built relationships and brought kindness and professionalism to every visit.

Her retirement is well-deserved, and she will be greatly missed.”

Retirement has ushered in a new chapter for Kerry - one she says has kept her busier than ever. Travel has always sparked joy. She loves going anywhere, with recent trips to Croatia and New Zealand standing

out. Far from slowing down, she has new adventures already lined up: first Greece, then Portugal, alongside plenty of cottage time, gardening, tennis, volleyball, crafting, pickleball, and time with friends. Family anchors her – two children, one daughter-in-law, and her high-maintenance black lab Duke, who keeps her on her toes every day.

From that Oakville garden centre to respected roles at Nutrite, Plant Products, and AllTurf, Kerry Whale's career was about showing up positively and fostering growth and connection. She leaves the turf industry warmer for her humble mentorship, team-building energy, and the quiet doors she opened for others. As she moves forward with the same guiding spirit, it's clear her influence will continue—not through fanfare, but through the lasting bonds she created and the example she set of thoughtful, fun, and resilient professionalism.

Rob Ackermann, General Manager and Superintendent at Weston Golf Club and 2025 William Sansom Distinguished Service Award recipient, presents Paul Scenna, Superintendent at The Toronto Golf Club, with the 2026 William Sansom Distinguished Service Award. .

Paul Scenna Receives the 2026 William Sansom Distinguished Service Award The William Sansom Distinguished Service Award recognizes individuals who demonstrate exceptional leadership, long-standing service, and a lasting impact on the turfgrass industry. Paul Scenna’s, superintendent at The Toronto Golf Club, nomination reflects the deep respect and admiration he has earned from peers across Ontario.

Paul’s career-long contributions to the turfgrass industry exemplify the spirit and significance of this prestigious award. His impact on golf course management in Ontario is both far-reaching and enduring, defined by leadership, innovation, and an unwavering commitment to professional excellence.

Throughout his career, Paul has demonstrated outstanding leadership not only in his day-to-day work as a superintendent, but through the successful execution of major projects that have set new standards for course conditioning and sustainability. At Donalda Club, he led an extensive greens renovation in the late 1990s and early 2000s, a project that showcased both vision and precision and elevated course performance. In 2009, he oversaw the installation of a state-of-the-art irrigation system, requiring significant technical expertise and coordination.

From 2009 to 2019, Paul’s influence continued at Beacon Hall Golf Club, where he guided numerous improvement initiatives that strengthened the course’s character, playability, and long-term sustainability. Under his leadership, Beacon Hall successfully hosted several 20

prestigious events, including the Copa de las Americas International Amateur Championship and a U.S. Open Qualifier, reinforcing its reputation as a world-class golf facility.

Beyond an impressive career, Paul’s most lasting legacy may be his mentorship of future industry leaders. The number of professionals who credit him with shaping their careers is extensive, and his influence has played a significant role in developing the next generation of turfgrass managers.

A CGSA Master Superintendent, Paul also served as President of the OGSA during a pivotal period in the association’s history. In 2004, he led the launch of the first independently organized OGSA conference, introducing a free, full-day seminar that established a lasting precedent for value and member engagement.

Paul championed to move the conference to Niagara, demonstrating strategic leadership and responsiveness to members and industry partners. Paul helped to guide events to foster camaraderie, professionalism, and meaningful relationships within the board—connections that continue to influence the association today.

Paul’s lasting impact is reflected in the courses he elevated, the professionals he mentored, and the OGSA he helped guide through meaningful change—leaving a legacy of leadership, service, and excellence that continues to shape our industry.

OGSA Future Leaders IN PARTNERSHIP WITH

A highlight of this year’s conference was the continued inclusion of the Future Leaders Program, delivered in partnership with BrettYoung.

This long-standing partnership remains a cornerstone of OGSA & BrettYoung’s commitment to encourage young talent to pursue careers in golf course management, while providing meaningful networking experiences that benefit both students and members.

Equipment Manager Education IN PARTNERSHIP WITH

The conference also marked the introduction of an exciting new partnership with Milwaukee, which supported the launch of the Equipment Manager Education Series. This brand-new stream added valuable, targeted education to the conference schedule, recognizing the critical role equipment managers play in golf course operations. Sessions were hosted in the Petun Room on the second level of the Blue Mountain Conference Centre, and provided practical, hands-on learning opportunities focused on tools, technology, and best practices.

Written by Dawson Riml, Associate Superintendent, The Club at North Halton & Steven Mann A.Ag, DCS Agronomic Services.

Trees are among the most defining and emotionally charged features on a golf course. They frame holes, influence strategy, contribute to environmental value, and often carry deep sentimental meaning for members. At the same time, unmanaged or poorly placed trees can compromise turf health, alter architectural intent, increase maintenance costs, and create safety concerns. For modern golf facilities, developing a comprehensive tree management plan is essential but its success depends as much on member support as it does on agronomic science.

Many golf courses were designed with far fewer trees than what exists today. Over decades, natural growth, memorial plantings, and beautification efforts have

significantly increased tree density.

While often well-intentioned, this expansion has led to excessive shade, restricted airflow, and root competition.

Architecturally, encroaching trees can narrow fairways, eliminate strategic options, and obscure original sightlines which fundamentally change how a course is meant to be played. Add in safety and liability concerns from aging or structurally compromised trees, and the need for proactive management becomes clear.

A tree management plan is a longterm, strategic framework that guides decisions about planting, pruning, preservation, and removal.

Rather than reacting to individual problem trees, the plan aligns tree

management with agronomic goals, architectural values, and environmental stewardship.

The foundation of the plan is a thorough inventory and assessment.

Each tree or stand of trees should be evaluated by health, structural integrity, and impact on turf and playability.

Common goals include improving sunlight and airflow, enhancing turf health, restoring design intent, increasing safety, protecting specimen trees, and promoting ecological balance. These objectives should reflect the club’s identity and long-term vision.

Equally important is phasing. A multiyear implementation plan minimizes visual shock, spreads costs, and APRIL 2026 | ONCOURSE 25

2026 OGSA TURFGRASS MANAGEMENT CONFERENCE allows members to see benefits develop gradually. The plan should be documented and reviewed regularly as course conditions evolve.

Even the most carefully constructed tree management plan can face resistance if member concerns are not addressed. Trees are deeply personal. Members may have planted them, watched them mature, or associate them with favourite holes and memories. Removing a tree can feel like erasing part of the club’s history.

Recognizing this emotional attachment is critical.

Tree management is not just a maintenance issue; it is a cultural one.

Success depends on trust, communication, and respect for member sentiment.

The most effective tree management programs begin with education.

Before any trees are removed, members should understand how trees affect turf health, playability, pace of play, and long-term costs.

Visual tools such as shade studies, airflow diagrams, and before and after photos are particularly effective in illustrating these relationships.

Framing is essential.

Tree management should be presented to improve golf, not as an attack on trees. Healthier turf, firmer playing surfaces, restored strategy, and improved aesthetics resonate far more than technical explanations alone.

Trusted voices strengthen the message. While the superintendent often leads the effort, support from the golf professional, course architect, or an independent arborist adds credibility. A unified message from club leadership reassures members that decisions are thoughtful and well-informed.

Transparency builds confidence.

Sharing maps, marking trees under consideration, and clearly explaining why specific trees are targeted, helps prevent speculation and misinformation. Just as important is highlighting what will remain.

Emphasizing specimen trees and environmentally valuable areas reinforces that the plan is balanced.

Phased implementation allows members to experience tangible improvements, often within a single growing season. Increased sunlight, healthier turf, improved drainage, and stronger playing conditions are difficult to argue with once they are visible and playable.

These early successes often shift the conversation from opposition to support. What begins as skepticism can evolve into appreciation as members see the course improve.

Inviting feedback along the way, while maintaining commitment to the plan’s goals, further strengthens trust and engagement.

When a tree management plan is well designed and well communicated, its benefits extend far beyond the trees themselves.

Maintenance becomes more sustainable, budgets more predictable, and future boards less likely to reverse progress and trust grows between the membership and course leadership.

2026 OGSA TURFGRASS MANAGEMENT CONFERENCE

Winter Isn’t What It Used to Be Written by Chris Lecour, Turf Sales Specialist, BASF.

Two decades ago, golf courses across Ontario and Quebec could count on a familiar winter pattern: deep cold, persistent snow cover, and then a slow, steady thaw in spring. Under a snow cover that could last for months, disease pressure on cool‑season turf was more predictable and straightforward. The threat of gray and speckled snow mold was predominant with some pink snow mold flaring up in regions that experienced milder temperatures and less permanent cover. Since gray and speckled snow mold are not active in temperatures below 0°C, a final snow mold fungicide application in the fall, along with frozen turf and natural insulation from the snow, was all the insurance needed for superintendents to produce an acceptable playing surface the next spring. Changing weather patterns over the last two decades have made it more challenging to protect against winter turf pressures. Winters along the Great Lakes and St. Lawrence corridor are now shorter, warmer, and wetter.

There are more rain and wet snow events, frequent freeze-thaw cycles, and far less reliable lake ice and snowpack.

Fusarium or pink snow mold is becoming more common and problematic than it used to be twenty years ago in this region. Researchers estimate the Great Lakes have lost roughly 14 winter days since the mid‑1990s, a significant shift that leads to more winter rainfall, runoff, and mid‑season thaws. Those conditions create two challenges for superintendents: a hospitable environment for snow mold incubation, while making it physically difficult to reach areas that require a fungicide application.

Gray and speckled snow mold are active between 0°C and 3°C under high soil moisture and high humidity conditions, just the type of winters that courses near the Great Lakes have been experiencing recently.

Microdochium has a wider temperature range (0°C – 8°C, even up to 18°C under prolonged high moisture conditions) and can thrive on unfrozen turf with or without snow cover, making it a real problem for Ottawa and Montreal area golf courses in recent years.

It would be one thing if a mid-January thaw melted all the snow on the golf course AND the ground firmed up enough to support the weight of a sprayer.

Unfortunately, this is rarely the case. Exposed turf in January that might benefit from a supplemental snow mold application (the high unexpected and not-inthe-budget application cost notwithstanding) would APRIL 2026 | ONCOURSE 29

be difficult to reach with a fully loaded sprayer and would inevitably damage the turf it was trying to protect along with other areas of the golf course. Snow mold outbreaks are not the only issue with warmer winters. Increased rain and melt events with fluctuating high and low temperatures increase the risk of ice formation and crown hydration injury on sensitive turf areas. Bentgrass is better suited to survive these fluctuating winter conditions, but Poa dominant turf can suffer damage quickly. Poa will begin to de-acclimate at the onset of warmer temperatures in as little as 48-72 hours.

Freeze–thaw volatility raises the stakes for crown hydration and ice.

Using distinct FRAC groups in multiple fall applications is key to reducing the risk of snow mold and Microdochium patches on golf turf as winter approaches. Snow mold pathogens— particularly Microdochium nivale and the Typhula species—thrive under prolonged moisture, low light, and extended snow cover. Rotating and combining fungicides that are effective on snow mold with different modes of action, such as FRAC groups 3, 11, 12, and 19 along with a contact fungicide reduces selection pressure on any one chemistry and prevents resistance development, ensuring longer-term product efficacy. Multiple applications prior to snowfall provided a layered protection strategy: early fall sprays suppress existing inoculum, while late-fall applications provide residual control that persists into and through snow cover. Combine systemic and contact actives to improve disease suppression under severe or long snow cover. Diversified disease control programs and well-timed fall applications maximize disease control, improve turf winter survival, and ensure healthier surfaces on opening day.

Warmer winters with intermittent thaws and mid‑winter rain tend to de‑acclimate turf and re‑hydrate crowns.

Subsequent refreezes can rupture cells. Ice encasement also limits oxygen at the surface, and even short-duration events can injure Poa‑dominant greens in low, poorly drained or shaded sites. These damage prone sites should be evaluated well before winter, and conditions improved focusing on improving surface and subsurface drainage, air flow and shade issues.

Canadian superintendents face more shoulder‑season management and fewer “set‐and‐forget” winters. Shorter winters with less consistent snow cover and more rain events require a winter program that addresses microclimate issues and recognizes the value in a multi-pronged snow mold fungicide program that uses multiple FRAC groups for short and long-term success.

CLIMATE DRIVEN ISSUES TO HAVE ON YOUR RADAR Gray snow mold may be more inconsistent, but it has not disappeared.

Gray snow mold still matters in areas that retain deep, persistent snow, but its severity is increasingly variable as winter conditions can fluctuate.

Differentiating Microdochium (fusarium) from gray and speckled snow molds (typhula spp.) remains essential for product choice, application timing, and expectations.

Microdochium keeps working—even without snow.

With fewer long, continuous snowpacks, Microdochium nivale has shifted from the “classic” pink snow mold under snow to Microdochium patch during open, cool, and wet periods from late fall through early spring. Expect activity whenever temperatures are 0°C-8°C with prolonged leaf wetness, particularly on Poa annua and close‑mown bent surfaces. That means visible injury in December through March—even in winters with little or no snow.
