Tourist Visa / Visitor visa:
The visa for the purpose of tourism.
There are two types of Canadian Visitor Visas, one for single entry and another for multiple-entry use.
Single entry visas are granted for a period of up to 6 months while the maximum validity date for multiple-entry visitor visas is up to 10 years or one month prior to the expiry date on the passport or re-entry visa (whichever date comes first). You'll only need a multiple-entry visa when travelling in and out of Canada, for example, you may land in Canada, travel to countries in South America, and fly back to Canada again to travel home from there.
