Travelling Abroad
This is the Service Canada website for the "Life Event" travelling abroad. It includes links for important stuff like getting a Passport, changing money, health warnings and required vaccinations, thinking about travelling with children, getting an International Driving Permit, getting back into Canada (Customs) and a link to help you find Canadian Government Offices in other countries. Basically, if you're going outside the country, check this site, because while you may have found everything you need to know elsewehere, you don't want to arrive in Botswana at midnight and realize you've lost your passport and money, and have no idea where the Canadian Consular Office is.
Voyage.gc.ca
Yes, you can get here from Service Canada, but it's worth mentioning anyway. Here's where you find the list of Canadian Government Offices abroad, security warnings (you know, don't go to Afghanistan because there's a war on, that kind of thing), country profiles, links on health matters, what countries you need a visa for, advice about dual citizenship (which is basically: stick to your Canadian Passport, and don't mention your other nationality, and they have a point--I'm Canadian-American and half the US boarder officials I've ever encountered aren't even aware that it's possible to have dual citizenship and think it's somehow suspicious to claim to), and all sorts of other things you need, especially if you're going somewhere that isn't a major tourist destination for Canadians.
Passport Canada
Just in case you've ignored all my advice above, here's the one link you really better follow, or you aren't even going to make it out of Canada. Note that you can now use almost any Canadian Passport holder you've known for two years or more as your Guarantor--even family members, rather than having to find a Professor, Principal Priest, Judge, etc.
Tourist Visa Requirements
This is another you'd better check even if you ignore the first two sites above (but don't). Lots of countries need visas just for travel, and if you're going to study or work in another country, you will definitely need a Student Visa (you can't get details of that from the Canadian Government, I'm just warning you).
Exchanges Canada
This is a Heritage Canada site which provides details on various youth exchange programs, and is a good place to go if you think you want to go abroad, but aren't quite sure where or how. Plus, exchange programs usually mean you don't have to do all the worrying and paperwork yourself, which can be really nice, and especially if you've just entered the adult world (and I don't mean legally, it depends on how long you've lived away from home, how many bills you've paid, etc.)
