Can U.S earned Healthcare Admin B.S. work in Canada?

I you aren't a Canadian citizens you can't work in Canada without a work permit. In order to apply for a work permit you must have a job offer from a Canadian company which has permission to hire foreign workers. That company must apply for a Labour Market Impact Assessment (LMIA) report which shows a shortage of Canadian in that profession along with proof that they advertised in Canada and no Canadians applied. Such job offers are rare. Expecting one in a specific city is next to impossible. Work permits are also temporary... a few years or until your job offer ends. Few companies are likely to go through this for temporary administrative workers.

It is highly unlikely any US health administration degree would be of much use in Canada. Canada has a completely different system of laws, policies, regulation, etc. It is also unlikely that you would have much relevant work experience.

If you are a Canadian citizen... I have no idea why you would be taking a US bachelor's degree.

Canada usually accepts US degrees. however the job duties and requirements may differ from similar positions in the US.
