Years ago they built a bypass around the town of Kenora so you did not have to go through it while on the TC Hwy. There are rock cuts all along the TC Hwy in North Western Ontario so these rock slides do happen but I have never seen a boulder this big on the road here. It's something I might expect in the Rockies. If your timing was bad it could really ruin your day.
