Last winter, after a period of freezing rain, I had a large deer with a broken left foreleg at my bird feeders...it was hard to accept that there was nothing to be done...and that it would be part of the food chain shortly.
In the summer, we had a young bear that had been hit by a van (driven by a Mennonite no less)...it was in pain and the OPP had been called....with no way to get it quick treatment they were forced to dispatch the poor thing...and a surprising problem that arose came from the fact that cops are taught to shoot people not animals like bears and the poor officer was traumatized...it apparently took more than one shot. The problem was they couldn't leave it to fend for itself because it could very likely have led to bigger problems.
You have to remember, the vets out here don't have tranquillizer guns like in the movies...and aren't trained to work on bears...
I'd be really surprised if the City of Brampton could do anything other than euthanize the animal.
