Dude, even if you have a Canadian child today who are able to sponsor you, it's not guaranteed. There's a lottery and only 10% of the applicants who are financially ready to sponsor their parents are accepted. And this is today! Wait until the trump-like racists (e.g. Bernier) get to government. It'll be worse than the US because at least Trump is blunt. Canadians will keep telling themselves they're open and welcoming etc but it'll only get worse and more closed.
You're better off investing that money & time elsewhere, and have your kid go study. Being highly-skilled with a good education will always be sought after and all countries will want your kid. Or immigrate yourself. Anchor babies is just a waste of money. And for tourism, there's nothign to see in Canada. This is from someone who lived there for 7 years and moved away to greener pastures. You'd be much better served visiting Europe as it is much more fun & richer, more diverse culture (and closer = cheaper tickets).
