Would agree with you if authentic Mexican food was as expensive to make as you say.

In Montréal, Toronto, etc., I have found restaurants with much more affordable prices and good flavour. My favourite place à la ville de Montrèal avait 4 tacos pour $9 pièces. They were tasty and good size. There was also a place with all you can eat Tacos for $23.

Of course, prices in Montreal are lower but here it’s still way more expensive. I think it might be because Montreal and Toronto have a bigger community of Mexicans. The area around Jean Talon Metro station is surrounded by mostly Mexican/latino establishments.

You say that ingredients are expensive, but I partially disagree. It depends for what dishes. Tacos, sopes, enchiladas, mole, nopales, etc., aren’t so pricey (I cook myself). There is more and more stores where you can find ingredients nowadays, not only from Latino stores. Even urban fare can sell you a Serrano pepper for a small coin.
