Citizenship and Immigration Canada defines Visitors as people who wish to enterCanadafor a temporary purpose, such as tourists, temporary foreign workers and international students. All Visitors to Canada must apply for and be granted Visitor Visas by Immigration Canada unless they are citizens of visa exempt countries.
All Visitors must always satisfy the immigration official at the port of entry that the purpose of their visit into Canada is of a temporary nature.
Visitor Visas may be for single entry, multiple entry, or transit purposes. If needed, visitor visas must be applied for and obtained from an Immigration Canada Visa Office outside Canada. Only Visitor Visa extensions may be applied for within Canada. As a general rule, tourists are admitted for a period of six months. Temporary foreign workers and international students are admitted for varying periods of time, as determined on a case-by-case basis.
Transit Visitor Visas allow entry into Canada for a period of no more than 48 hours, and apply to foreign individuals whose bus or flight stops in Canada on route to another country.
