Do large amounts of Americans move to Canada because the United States tend to be such a mess?

Actually, imbecile, many more Canadians move to the USA than vice versa.

Americans cannot legally move to Canada without being allowed to immigrate in.

IDK.. but thanks for the information.  USA is in a mess and will only get worse now that we have this puppet in action.  Checking on moving to Canada tomorrow.

Not "large amounts" because Canada only allows a finite number of immigrants each year and that number is roughly 1/4 of the what the US allows per annum. 

Canada only accepts about 10,000 Americans every year, so "large amounts" is not exactly true.  They come for various reasons, but especially economic ones.

Actually more move from Canada to USA due to more economic opportunities.

No as most wouldn't qualify for a visa to live in Canada

How large is "large"? I'm guessing you don't have a clue.

No.

In the first place, the US is not  a "mess".

In the second, you can't just pick up and move to another country, Canada included. You have to meet certain requirements, and most Americans wouldn't do so. 

The Americans I know who've moved to Canada have either married Canadians or received job offers there.  Of course, there are some illegals, though not nearly as many as illegally immigrated during the days of the Vietnam War.

In other words, Americans aren't "flocking" to Canada.

No it's because they love the Canada Geese.

BTW a lot of Canadians emigrate to the US each year and become US citizens, like Alex Trebek did.  My point...Canadians are coming to the US as much as Americans are flocking to Canada.
