Toronto
Canadians love their hockey, they love their beer, they love their universal healthcare and a large number of them love their football.
Walk down any street in Canada's biggest city on a weekend and you're bound to see a football 'jersey' or two. Sure, you'll see the biggies: Chelsea, Liverpool, Manchester United, A.C. Milan, Real Madrid, Celtic and so on. But you'll also see more exotic outfits: St. Pauli, Panathinaikos, Queens Park Rangers.
If there isn't snow on the ground (usually the months outside of November-February) and the temperature is above zero, then you will likely find games of pick-up football happening in the two large downtown parks, Trinity Bellwoods Park and High Park.
If you join a game, you might want to keep your eye out for flying baseballs, Frisbees and dogs using your bag as a fire hydrant, but the typically friendly Torontonians love to meet new people, and if you have a wacky British accent then they will assume you're decent with a ball at your feet. So, no pressure.
