Robertson recorded the bear as it crawled to the edge of the porch and leapt over to a nearby tree.
"It was surprising to see one this close on the deck, but we are sort of on their turf, so it is sort of to be expected," he told CTV News.
Robertson said he measured the distance from the deck to the tree, which he said ended being about seven feet.
"I've never seen a bear jump at all, let alone that kind of distance," he said.
