You'd still be wise to get a Canadian passport, though. It's a lot quicker to replace if lost than a citizenship certificate, and won't confuse airlines that expect Canadians to travel on Canadian documents.

There's no need to give up your British passport when you do that; you can carry on using it for entry to the UK and for other countries (such as those in the EU) that offer smoother entry to British citizens.

While plausible, Bristol's scenario sounds far-fetched, and could in any event be overcome with other evidence of presence in Canada during the period in question.
