I’ll try to save you a bunch of work and reading. You don’t need ADS-B in Canadian Airspace below 18,000’. You just need a transponder if operating in Controlled Airspace. We’ve got lots of Class E airspace....”empty”
Your route.... I randomly selected Portland Maine to Juno just for sh*ts and giggles. The great circle distance is 2,415nm. I then put in a routing that has a few options for overnighting and fuel options that takes you way north of the beaten path, but yet not in the officially “sparsely settled” area of Canada. This distance then went up to 2,455nm. The longest leg in the photo below is 520nm, a tad long, but many other stops nearby to shorten the leg without affecting the total distance more than a few miles. This should take you around most of the nasty terrain, but I’m out east, so the guys who have commented above would know better than me. Not a very glamorous route, few attractions, but the shortest. Check the price of avgas at airnav.com or other app, some northern airports have high fuel prices.
Have Fun! Carl
