NO , you can't borrow a gun to shoot a deer. You need a license to hunt anything in Ontario. You need to take two courses. PAL which is your firearms acquisition and possession and then apply to RCMP to be given the license. Takes around 3 months. You also need to take your hunter ed course in order apply for your Outdoors card...hunter version. Then you need additional individual tags for each species. I just did all of it....this isn't like america...they dont just let anyone run around with guns in this country.....lol
