It's too much and that sort of population boom can be bad. Canadians that would have been living in the major metros can no longer afford to as housing prices have skyrocketed with demand. Same issue in Australia, I will probably never be able to afford to live in one of the major cities.
It's kind of unfair to some people, it's bizarre how much immigration is pushed as a 'good thing' but it isn't a 'good thing' or a 'bad thing' it's just something that happens, and while extreme consequences for better or worse. I'm an immigrant and I'm anti-immigration for the most part. It sort of works in a place like the USA because it's so big and can handle an incredibly huge population, but Canada and Australia just can't.
It's not like people immigrate to Winnipeg or Calgary. They want Vancouver and Toronto. People don't move to Toowoomba or Newcastle, they go to Sydney and Melbourne. Then it's just the smart and capable people moving, it just causes a brain drain on the migrant's country. My wife's parents were both doctors, are two doctors more valuable in the Philippines or the USA...? I'd say the country with people living in destitute poverty needs medical help more than literally the richest nation in existence. I don't blame people for leaving either, why stick around in a kleptocracy (the Philippines) or a theocracy (Iran) when they can live in the home of the free, land of the brave where the USA's inherit problems are hardly their concern?
