I can't knock the US, it's a great country, and great people.
Canada is quieter, and you will have more opportunity to fly, with less traffic. Canada can offer everything that the US can in aviation, and a lot more variation than Florida. Float and ski flying are two examples, and you'll get better at navigation, because you have to do it more! There are many larger areas over which to fly, and every kind of runway you could ever want to find to practice on. Not too many 1200' grass runways in Florida, but we have 'em here. And, if worse comes to worse, and you have to put it down, the creatures you meet once you're down are not trying to eat you! Flying across the Everglades is quite intimidating!
As for weather, yes we have our bad times, but bad means you could not get a good weather day for a week. Generally, you could fly nearly every day thoughout most of the year if you wanted, in most parts of Canada. When the weather is bad, it's not 150 mph winds blowing airplanes inside hangers away, it's just blowy with rain or snow, and the possibilty of summer thunderstorms.
Have a good look at Canada before you commit to the US.
