These 2 are arguably the hardest countries to tell apart in GeoGuessr. Roads, cars, buildings… Everything looks so similar. However, there are a few tricks you can use to tell Canada and the USA apart. Beware, that many of those tips are not foolproof, you still might see metal signposts or a double yellow line in Canada or a parking sign with a black outline in the US, for instance. Nonetheless, things like “Speed Limit” and “Maximum, the verbosity of signs or petrol prices are good indicators of where you are. Roads in Canada might also look a bit less well-maintained than in the US. Additionally, there are some big retail/restaurant chains, that are exclusive to each country:

– LCBO (Ontario only), Loblaws, Sobeys, No Frills, Fortinos, Zehr’s, BMO, RBC, CIBC, Scotiabank, Mac’s, A&W, Tim Hortons (mostly), East Side Mario’s, Harvey’s, Chapter’s/Indigo are found only in Canada
– Target, Kmart, Barnes and Noble, White Castle, Sonic, Carls Jr, Whataburger, Olive Garden and Dunkin Donuts are only found only in the US.
