There's nothing wrong in learning about your neighbour to the North. I'd love to point out guys like you to the ignoramus jerks I meet here who say that Americans know nothing about Canada (and then spout out the most ridiculous generalisations about Americans and the US).
However, you shouldn't overlook the drawbacks as well. One of the biggest ones to living here is that many people will outright hate you just for being American. It has happened to me a number of times. Not being from the South (the Southern accent being confused by a lot of the above-mentioned dummies with the typical American accent) I can usually "pass" pretty easily if I want to. But then I have had perfectly harmonious professional and personal relationships go South (no pun intended) as soon as the other person finds out that I'm American. Yeah, it's so obvious that Americans are bad people that you figured that out about me right away—but after months of getting along with me you now decide that I'm a jerk just because of where I was born. Whatever.
I'm not saying Canadians are narrow-minded in general—but I've certainly met a good number who are. I include a lot of well-educated professionals in that group. I got so sick of it with one woman who considered herself a good friend but never failed to get in the obligatory dig about my origins that I stopped associating with her—just as I did with one who said she was bent on "Canadianising" me (whatever that means), but in reality was using my lack of confidence in a new country and defensiveness about being an American to her advantage (this was a work supervisor) to get me to do way more than should have been expected of me (and more than was expected of everyone else in my position), in an unnecessarily highly-pressured environment. I've also had to deal with bullying and sexual harrassment at work and amongst my neighbours—this is primarily from white, native-born Canadians. Add serious cultural and political resentments from a lot of the Southeast Asian immigrants in my neighbourhood (there's a reason why they came here instead of the US), and it gets old really fast.
At the same time, I caution you against blinding yourself to some of the great things about the US. It's an easy trap to fall into just because of the many detrimental things you see in the media and around you. For me, it has been a blessing to have two PBS stations (Seattle and Detroit) to choose from here so that I can get a regular reminder of the good things about the US: especially culturally and historically. It's good, too, to remember that, just as so much of what's good about the US has its downsides, so do a lot of the things you admire in Canada. Canada's treatment of its Native population through history is no more admirable than ours; and here on the West Coast Japanese Canadians were interned during WWII just as they were in the States. Racism exists here just as it does in the States—it just takes a very different guise, and is harder for those used to American-style racism to recognise.
I think it's great that you're interested in another culture and want to live outside the US. It has long been a goal of mine. I was so disappointed after I got married that my husband wanted to remain in the US instead of return to Europe, as I had been desperate to leave the country permanently since quite literally before you were born. When I left the US in the shadow of the build-up for the Iraq war, I felt very fortunate. Having some income sources in the US, however, I get to pay taxes to the very government I'm trying to get away from. Knowing that my money is going to repress the people I left behind is not a happy thought. Plus, my friends in the US have all but branded me a coward for "running away".
Sorry to go on, but I have a feeling that I know what motivates your interest in emigrating, and if there's anything I can provide for you it's a walking advertisement of how that dream can go tremendously wrong. If you make it past potential draft age without leaving the US and still want to go elsewhere, why restrict your options to Canada? There's another country to the South, too, and plenty of other places throughout the world—some of which could provide a better potential "fit" than an increasingly restrictive and xenophobic (at least as regards the US) Canada.
