There is a thing in theory, called the trans-canada trail. A guy cycled it a few years back, and they had his day to day log on the TCTrail.ca website. He was a pretty good writer. so that it was a fun read. I went back to look for it, and it was gone. However, the part I read that he had done in fall was the east coast to Manitoba. When I covered the same territory myself, I found the TCT was the last place I wanted to bike, in most cases, because the road surface was so slow. I don't know what if anything the TCT amounts to out west.
The only web vestige I could find for Tom Couture's TCT trip was in German:

I did have an email adress for him for a while, but it no longer seems to work.
