So a Canadian that wants to visit on a tourist visa has to apply at an embassy?????!!!! Instead of on the airplane right before landing?

Insane. This is going to destroy the tourism industry and collapse business travel.

Canadians don't need a visa to visit the United States for tourism or temporary business travel purposes.

Canadians don’t need a visa to visit the US, they are visa-exempt.

This doesn't affect nationals eligible for visa-on-arrival.

Do Canadians need to get Visas to visit the US ?

Last time I went to Canada all I needed was a Passport. I do not even remember showing it to the Custom Official. I drove up said hi and they let me through.

As far as I know it was/is the same for Canadians visiting the US. Except the US border people tended to be d**ks, even to US Citizens.

Did that change?

Canadians do not need a visa to enter the US. And many countries are covered under the Visa Waiver Program, such as many European countries. So no, this does not affect Canadians.
