Why not head farther west along I-90 or Hwy 2 and grab Hwy 97 north at some point as there are a lot of way to get to it.
Enter Canada at Osoyoos and follow Hwy 97 north to Prince George to Hwy 16 west to Kitwanga and then take Hwy 37 north past Stewart / Hyder to just west of Watson lake where you join up with the Alaska Hwy.
Then on the way home once at the Jct west of Watson Lake continue on the Alaska Hwy down to Dawson Creek, then east over to over to Grande Prairie, then south on Hwy 40 south through Grande Cashe where you will join up with Hwy 16 just east of Hinton Alberta and follow it west to Jasper where you will join up with the Ice Field Parkway.
Also,if you give the dates your coming through, it would have a better idea of the Salmon spawning ( bear viewing) at Stewart / Hyder.
Great route.
I pull a 33.5 ft 5th Wheel all over BC and Alberta, never had an issue, just never go down a hill any faster than you went up it.
