The national collision database draws from statistics assembled from each of the provinces and territories. We work closely with the provinces and territories through the Canadian Council of Motor Transport Administrators. We depend very much on that close collaboration to be able to assemble that dataset. I'm happy to say that just recently, within the last month, the 2017 dataset has been added to the national collision database as well.
On April 4th, 2019. See this statement in context.
