Working in Canada
Foreign individuals who wish to work, study or visit Canada on a temporary basis are considered Visitors. Visitors must apply for and be granted Visitor Visas, unless they are citizens of visa-exempt countries (USA, Western Europe, British Commonwealth, for starters). Those wishing to work temporarily in Canada will also often require Employment Authorizations (and htose wishing to study temporarily will need a Student Authorization). NOTE: Visitors will be denied entry into Canada if, in the opinion of a Canadian immigration official at the border or airport:
