Some pubs in Toronto describe their food as CANADIAN.
Before I respond to your suggestion, I would like to point out that i don't work for TripAdvisor. As with all Destination Experts, I'm a TA member like you who volunteers to help fellow members with their questions.
When submitting a new restaurant, or updating the information for an existing restaurant, you can specify Canadian cuisine, and once TA processes the information, "Canadian" will be shown as the cuisine type on the restaurant listing, such as this one:
(BTW, I found this example through Google, using the search string
"Cuisines Canadian" Calgary site:tripadvisor.com )
The problem is that TA does not yet filter for all the types of cuisine that it allows on listings. For example, you also can't filter for halal food, even if the restaurant has "halal" as the cuisine on its listing.
In other words, I agree with you, TA ought to get their act together and allow you to filter for every cuisine type that they have set up in their database.Edited: 30 March 2014, 23:09
So what distinguishes Canadian cuisine from other North American food?
Tim Horton's donuts!!!
Ketchup chips ;-)
Canadian food is polite, friendly and frequently says, "Sorry." :-)
Silvia has nailed it. TA doesn't need a separate descriptor for this: http://en.wikipedia.org/wiki/Poutine
Traveller Article on Canadian cuisine:
What about ice wine?
Thanks for the reminder, Sodo - I added that to the article, along with donairs (a Canadian variation on the doner kebab / gyro).
