Lets see how many GTA fans want to see the series move to Canada.
Various games in the GTA franchise have shown us a wide variety of cities in the fictionalized version of the USA depicted in the franchise. We have been introduced to the not-New-York Liberty City, the Not-Los-Angeles Los Santos, the Not-Las-Vegas Las Venturas, and many more. Most GTA games provided the player with one large city map with countless things to do and kill, with all sorts of in game events and activities which hammer home the whole satirical, social commentary message of the game.

However, the GTA community has begun to theorize what other countries in this fictional universe may be like. GTA fans may have gotten a feel of this with the two expansions in the 2D era which were set in England. While dropping players off in a city in a country on the other side of the largest body of water may seem too risky for big-budget AAA development, Canada seems to be the perfect destination - but is it?
The GTA franchise has come into contact with Canada before on multiple occasions with the fact that Trevor himself is from up north. Setting the game in a non-US city would be a first for the current universe. The GTA franchise is deeply mired in satire and political commentary, and having the game set in a nation where the people are notoriously well-mannered is peculiar at best.
