Николь, смотри, что Гугль говорит:"A citizen of Canada will retain Canadian citizenship upon acquiring a second citizenship in another country.  In fact, Canadian citizens cannot lose their citizenship unless they voluntarily renounce it via a complicated legal procedure."In many ways, dual citizenship is a proud value for Canada and its citizens. Dual citizenship speaks to Canada’s diversity and comfort with multiculturalism. Many new Canadians opt to keep their previous citizenship in addition to their Canadian citizenship. In most cases, having dual citizenship is positive and beneficial - typical of many families in Canada, whether they are recently arrived or long-established.
