"Canadians of convenience" is a pejorative referring to Canadian citizens with multiple citizenship who live permanently outside of Canada or remain outside the country for extended periods without "substantive ties" to Canada. Some definitions use the term to refer to persons who immigrate to Canada, meet the residency requirement to become a naturalized citizen, and then return to live in their original home country while maintaining their Canadian citizenship. The term implies that these citizens only acquire or maintain their citizenship as a form of "insurance" so that they may call on the Canadian government for protection in the event of an emergency.
