Lutefisk and Surströmming in Toronto?
Good luck with your search. In my experience, depending on the treatment or regional origin of the lutefisk, it can range from horrific to passable tasting. I did experience a decent version from the homeland.
Surstromming? I won't touch that shit with a ten foot pole. I swear, from durian to North American processed frozen foods, every nation has something that's a stinkbomb. All the best though, you are clearly a strong human being ;)
