Highways in Canada

There was one near Kenora on the Hwy 17A bypass but it was related to construction and rock removal. Not because of erosion. https://winnipeg.ctvnews.ca/how-crews-cl...-blocked-a-highway-near-kenora-1.5335936

Here's one on Hwy 537 near Sudbury: https://kitchener.ctvnews.ca/video?clipId=613034

One near Dryden:

That's what I could find after doing a quick search. All of them had pretty quick cleanups and it was just rock not mud, trees, etc..

I believe the area just west of Sault Ste. Marie around Batchewana Bay and Lake Superior Provincial Park has some issues. Two years ago my family had a hiking trip up at Pukaskwa Park and had to detour through Chapleau because Hwy 17 was washed out west of Batchewana Bay. Then just a few weeks ago we were grabbing breakfast at the A&W in Blind River, and a heavy-equipment operator was in there heading to that same area as one lane was closed due to some rockfall. In both instances, though, I think the highway was reopened in relatively short order. Certainly nothing comparable to what BC or Nfld have seen just now.

I would be curious if it's even possible for Ontario to experience rainfall like they have seen. The Great Lakes are big, but I don't know if they are big enough for weather systems to pick up that amount of moisture. The most significant flooding event I'm aware of is Hurricane Hazel, which was a highly anomalous event, and damage from that was primarily due to irresponsible land-use planning practices of the time. If it were happen today, damage would likely be far more limited.
