Well assuming doesn't get you really far in life. I'm old enough that I remember when Swiss Chalet and Red Lobster were in Quebec. Swiss Chalet closed it's restaurants in Quebec because they couldn't make a dent in St-Hubert market (ironically, Swiss Chalet's parent company now owns St-Hubert), I recall all of the news feed on TV because I use to love going to Swiss Chalet as a kid. Red Lobster just weren't profitable in Quebec period, guess we're not that big into seafood (https://www.shlr.org/le-red-lobster-na-fait-que-passer-a-vanier-et-au-quebec/).
Canada is a freaking huge country and different areas will have different people meaning different tastes meaning different markets. Companies who don't do proper market research will learn the hard way that their business is not needed in certain markets. Hell, Target Canada is considered one of the biggest market research failure ever made, they couldn't make it work in any Canadian markets .
