That link refers to Newfoundland. Not sure it applies to all of Canada.

I called the # on the link way above. Handguns are permissible if you follow the rules & regulations as per the declaration form.

Anyone can come across a nasty boarder agent, happens all the time; but push comes to shove, there are formal regulations.

That's why they have rules & regulations in writing, otherwise it's all fake news. Call the authorities yourself, it's a public posted #.
