The Canada Visit Visa is a straightforward visa application giving you the ability to visit Canada for a period of up to 6 months. Single entry visas and multiple entry visas are the two types of Canada visas available in Canada. Foreign nationals can only enter Canada once with a single-entry visa. A multiple entry visa permits its holder to come and go as often as they desire while the visa is valid. You do not have to pick the type of visitor visa to apply for; all applicants are automatically considered for multiple entry visas, and single-entry visas are only awarded in exceptional circumstances.
