Canada and Australia go further with easier immigration process for first degree relatives, which is important in Asian culture. In Germany, for example, you need to be a minor in order to bring your parents or prove "exceptional hardship" [0]
Yes, playing the lottery is easy. Winning the lottery, not so much.
Canada does not currently have a viable immigration model for non-dependents immigration. The Parents-Grandparents stream takes 30,000 applications a year through a lottery system because demand is so high. So it could take many years before you get to bring your parents.
Canada has social healthcare that is already stretched to its limits in many areas. I'm not sure they can afford to take in every relative who wants to come but has never paid into healthcare.
It's not easy, because capacity is an issue, not just payment. Similarly housing, similarly other services.
Canada already has massive immigration relative to its population - the built environment and capacity for services hasn't increased relative to that immigration. It doesn't matter what insurance you have when there aren't enough surgeons, 130+ days wait for an MRI, etc etc.
Allowing "unlimited" parents per immigrant is essentially tripling immigration on its own. Maybe the answer isn't "limitless immigration" when the problem is lack of housing, capacity, and services.
In my opinion canada's immigration policies are already unsustainable and have cost a huge portion of the canadian population in quality of life.
>but why, though? Aren't there any surgeons among the immigrants?
because they can pick up and move to the states and double or triple their income, so the surgeons have to be people who expressly wish to stay in canada over increase their income.
> Don't immigrants generate tax revenues to pay for new infra?
that has not been the case so far. Housing, healthcare, etc are in crisis in canada. meanwhile the government is allowing fast food restaurants to import temporary workers.
Almost any country in the world allows you to bring your parents if you are a citizen. The path to citizenship in US is very very long. Canada allows this while you are on a PR. And not every immigrant is happy to change citizenship, it's a much riskier bet than being a PR.
