North Bend British Columbia - This websites news article from Thursday, 17 Nov 2021, contained the above video of a washout caused during the tremendous amount of rainfall responsible for multiple landslides and flooding across southern British Columbia with the subsequent blockage of road and rail routes into the lower mainland from the rest of Canada.
 
It was reported at that time this washout was POSSIBLY located on a Canadian National rail line.
 
However, it's now known to be located just east of the North Bend yard, which lies in the Fraser Canyon near Boston Bar, on Canadian Pacific's main line through British Columbia as seen in the photo below:
