According to a comment by McGillivray, the incident occurred on the Stewart Cassiar Highway between Stewart BC and Meziadin Junction.

“Don’t normally post on here but thought I’d share this incredibly rare and amazing moment with all you guys of these grizzlies fighting,” she writes in her post.

The two large grizzlies, while most prominent on the screen, aren’t the only wildlife captured in this video.

Keen observers can spot a little wolf watching the brawl from a safe distance of about a hundred metres.

See if you can spot him:

Don’t normally post on here but thought I’d share this incredibly rare and amazing moment with all you guys of these grizzlies fighting! Keep a sharp eye out for the little wolf that is observing them in the distance! 🥰🐻🐺
