Is dentistry considered a priority profession by the Canadian government for the purpose of immigrating to Canada?
Not at this time. Priority under the Federal Skilled Worker Program is given to those professions on the Skilled Occupations List established by Citizenship and Immigration Canada. Dentistry does not appear on the current list. That is why there is no guarantee that anyone is granted immigration status. The Canadian government controls issues of manpower for the entire country. The professions determined to be a priority are in constant flux.
It is critical that you contact Citizenship and Immigration Canada to determine your eligibility for migrating to Canada before committing time and money applying for our assessment protocols: http://www.cic.gc.ca/english/immigrate/skilled/apply-who.asp.
