This is BS. The laws exist coast to coast to coast. To even imply that our American friends could bring a restricted firearm into Canada and carry it is irresponsible. If caught it's potentially a three-year mandatory minimum no matter where you are in the country.In many of the rural areas of Northern Canada you will find few gun laws ACTUALLY exist.(i.e. are inforced) I carried a .44mag SRH openly for years without a permit and was only once asked about it by a RCMP officer. He asked if I had a permit. I said "no, I am a bear guide". He said, "oh, eh...ye ever had to used dat ting?"
More BS. There is not now nor has there even been a magazine limit of ten rounds in Ontario or anywhere else in Canada for a pump gun. That's the reason you had no problem with your Mossberg. It's a pump gun.In parts of Ontario it is still a maximum capacity of 10rds,....even though "provential law" states 5 rds for autos and higher for pumps. I had no problem obtaining and using a magazine extension for the 835 that brought maximum capacity to 8 2.75" shells when I was in Kapuskasing.
Anyone coming to Canada would be seriously well advised to ignore the advice that is posted by tango2echo.
