It's been about one week since a mother polar bear at the Toronto Zoo lashed out at her three newborn premature cubs, leaving one dead and the other two cubs in intensive care.

CP24 has the first video footage of the mother Aurora, the zoo's 10-year-old polar bear, swimming with a male polar bear.

Officials at the Toronto Zoo say the cubs are doing fine for now, but they're not out of the woods yet.

Zoo veterinarians and wildlife care staff have been giving the cubs "round-the-clock" care according to officials.
