IMO it depends on the field and her scholarships. If it's tech, just go to waterloo, it's a great school, has a great reputation and you get the Canadian discount, if it's not, you have more research to do. With her professors not having as much grant work to do, they might actually focus on teaching for once! As an undergrad, research doesn't matter much and no 17 year old is certain they want to become a PhD researcher type at that age.

Otherwise as dual citizens it's overblown. There is a lot of hot air in Canada that doesn't match the on the boots on the ground reality of life in the USA (for citizens / green card holders) because Canada is pissed off that America caused a downturn in Canada's economy and Canadians feel the pinch because the downturn is about 25% worse in Canada as a result.

But IMO it's self inflicted wound and has been a very, very long time coming. Canada has kept on kicking the economic can down the road for decades now and it's toll is collecting interest more and more.

The political worker class in DC is also very pissed off because the administration there initiated the equivalent of extreme mass layoffs in a sector that is not used to that.

In the USA, people are kind of mopey about the downturn, but in democratic areas the level of emotion is far less than it was with trump was the first time, while in Canada, it seems like it's more intense than it was in California with trump for the first time.
