Maybe your closer than me on the miles vs km. It's about 14 to 15 hours. I drove it very many times....not a too bad drive. ON TCH, it's mostly double lanes (unlike in 72), except for a couple of hours from the NB border to Riviere-du-loop.

I drove twice to Vancouver (return) awhile back, once through Canada, once through the northern USA states. Both are interesting in their own way.

The Maritimes welcome still stands....if your time is free...and are in the traveling state of mind. There's lots of good music and friendly folks throughout the east coast....as you likely know, since you have friends here, and travelled east coast before, (though awhile back).
