2023, the CCG will no longer be endorsed by ITE Canada as a best practice and national technical reference. The decision to retire this endorsement stems from several crucial factors that have impacted the guide’s relevancy and practicality within contemporary traffic engineering practices. The last publication of the CCG dates back to February 2008, rendering its data and methodologies outdated and requiring substantial efforts for an update. However, given the evolving landscape of traffic engineering and the pressing demands on resources, updating the guide does not currently align with ITE Canada’s priorities. Additionally, while the CCG has been used, primarily in southern Ontario, it was not embraced nationally over its decades of use.
