earth sciences and ecology question #3591

Jenifer, a 53 year old female from Vancouver, B.C. asks on September 3, 2006,

Q:

Recently I read that U.S. scientists say the ozone layer is shrinking over Antarctica. I would be interested to know what Canadian scientists say about the Arctic and Antarctic "holes". Do they agree that ozone is making a comeback and that the holes in the ozone are shrinking?
