I haven't looked to see where the accident happened, but the roads I am familiar with in Canada are unlike the roads in the US, for one there aren't roadside rest areas and gas stations with rest facilities like the US. Often no shoulder, the road goes from asphalt to bog or whatever happens to be next to the road. Truckers drive like maniacs .
This is an accurate description of rural roads in Northern Canada for sure. Grew up on them, now live in Urban US. It’s different. Absolutely heartbreaking accident.
