Thanks, Ian.
Some A-grade trails there, for sure.
Let me be immodest and give you my own recommendation: In 2016, I made a monthlong ride from just north of Jasper, Alberta, south through Waterton Lakes National Park to Montana, and then west to Washington state and the coast in the US. Most of that mileage was on public roads, rather than bike paths. But, I reckon the scenery was on a par with the ones in the Timeout link.
Here you go:
