Canadian localized food not found outside of canada
1. Hotdog stands with bacon bits and dozens of condiments. I noticed that its a Toronto thing to have hot dog stands with a dozen sometimes even 50 different type of condiments. Some even hide cheese and fried onions in the back (even though its illegal).
Just ask. As long as you dont look like a public health narc
2. Sriracha and hoisin sauce on vietnamese pho.
This is more of a vietnamese north-american thing. They do it in the states. I'm not sure about other countries with vietnamese immigrant populations like australia. But in vietnam, they don't have sriracha and dont eat pho like we do in north america.
It seems to be a way of eating vietnamese food thats been created by viet immigrants to north america.
I blame the great success of huy fong foods for creating sriracha sauce in the 70's
