Some highlights: "[...] you must meet some important immigration requirements. You must be in good health, law-abiding and have enough money to support yourself and your dependants during your stay." (and then there's also some other things that don't apply to me, such as staying there for more than 6 months, etc.)
Hum... "good health"... how do I prove that?
"law-abiding"... do I need some document for that to?
And then I found what I was looking for: "Before leaving for Canada, Citizens of the following countries and territories must apply for a visa to visit or transit Canada."
Portugal is not included
Now... IIRC, if you want to go to Angola, you have to show them that you have enough money to support yourself while there. I wonder if I have to do the same thing...
Well, better contact them directly, as I still have some issues.
