The Vancouver Sun reports that the video was posted to YouTube by Vancouver's Michael Fujiwara.
It says the sea lion was probably drawn by the fish in the area.
Fujiwara told the Vancouver Sun: "I was just sitting by the dock and then this sea lion popped its head out of the water just in front of me. I just took out my cellphone and started filming," he said.
"The sea lion actually attracted a lot of attention from the visitors there, including the young girl. She and her family, I guess, they came, they started feeding the animal bread crumbs or whatever it was, and then I guess the animal got a little too comfortable."
