... I, and a lot of people who live all over, even Argentina, think of food that's been infused with all sorts of hot/spicy/sweet/etc. flavors...
That's really funny. I was in Argentina last year and had their BBQ and other cooking methods of meat and if you want bland, go there. It was some of the most blah food I've ever tasted.
And every country suffers from the same type of negative comments from other countries. Have you seen the portion sizes in America, for example? Of course you have - you live there. I've never seen so much food on one plate anywhere else. Not to mention that free, refillable super-soda cups can be bought at Disneyworld for $1.89. Who can even contemplate drinking x number of 16 oz sized sodas?
I would agree that some Canadian food has been/can be bland, but there's some really fantastic Canadian food, too. Maybe you should watch some Canadian food network shows to update yourself. Michael Smith, Lynn Crawford, etc., are fabulous chefs, and right now, here in Calgary, there's a food war on between chefs of several major restaurants, not all of them high-end.
