Nearly 50 orcas belonging to the J and L pods were captured on video travelling through B.C.'s Active Pass near Galiano Island on Sunday.
Gary Cullen shot video of the whales, including a baby that playfully jumped out of the water, as they travelled in a group and dazzled onlookers.
"They just seemed to be having a good time," said Cullen.
"It was a pretty social party they were having."
The aquarium said the video isn't surprising because the tides and active water make the whales excited.
