A highway camera photo shows traffic in FortMcMurray jammed in the southbound lane of Highway 63 on the north side of the Athabasca River. The image was captured at 3:11 p.m. MT, about an hour after an evacuation order was issued for four neighbourhoods. (511 Alberta)

I had to check Google maps to make sure but the next closest city appears to be about 300kms south (Athabasca, unless Lac La Biche is closer), even with public transit they aren’t getting anywhere else. There’s nothing in so much of Northern Canada you’re screwed for mobility without a vehicle.
