For bears, it depends on what part of Canada you go to. Around here there are lots (even IN town). And they are getting to be a worse problem every year. Not a lot of attacks yet, but they are doing plenty of damage. One tore a neighbour's truck door off to get at a chocolate bar inside. Garbage bags and cans torn open and garbage spread all over. People afraid to go for walks.

Live traps are set but the bears almost always come back.

Their increasing numbers across north Ontario is widely blamed upon cancellation of the spring bear hunt a few years ago, a move made to please the anti-hunting lobbyists to the south. It harmed some businesses in the north for sure. I don't know whether it is to blame for the bear problems, but I do know the problems have increased since then.

There was a bear sighting in Nepean (near Ottawa) late last spring and it practically shut down the school system there for a couple of days till the yearling cub was caught. We have fully grown bears hanging out near schoolyards here all the time. Wonder what the reaction will be when a bear walks down the middle of Yonge Street in Toronto for the first time?
