A Ukrainian Canadian (Ukrainian: Український канадець, Українці Канади; translit. Ukrayins'kyi kanadets, Ukrayintsi Kanady) is a person of Ukrainian descent or origin who was born in or emigrated to Canada. In 2006, there were an estimated 1,209,085 persons of full or partial Ukrainian origin residing in Canada (mainly Canadian-born citizens) making them Canada's ninth largest ethnic group; and giving Canada the world's third-largest Ukrainian population behind Ukraine itself and Russia. Self-identified Ukrainians are the plurality in several rural areas of Western Canada.

Over the last thirty years,^[when?] a debate has been ongoing whether a tiny number of Ukrainians settled in Canada before 1891. Most controversial is the claim that Ukrainians may have been infantrymen alongside Poles in the Swiss French "De Meurons" and "De Watteville" regiments who fought for the British on the Niagara Peninsula during the War of 1812 – and that Ukrainians were among those soldiers who decided to stay in Upper Canada (southern Ontario). Other Ukrainians supposedly arrived as part of other immigrant groups: claims that individual Ukrainian families may have settled in southern Manitoba in the 1870s alongside blocks of Mennonites and other Germans from the Russian Empire; or that single male Ukrainians were participants in the Russian Empire's exploration parties and fur trade along the western coast of North America (including British Columbia). Because there is so little definitive documentary evidence of individual Ukrainians among these three groups, they are not generally regarded as among the first Ukrainians in Canada.

Justin Pierre James Trudeau, MP (born December 25, 1971) is a Canadian politician. He has represented the Montreal electoral division of Papineau in the Canadian House of Commons since 2008 as a member of the Liberal Party and currently serves as the party's critic for youth, post-secondary education, and amateur sport.

Trudeau is the eldest son of the late former Canadian prime minister Pierre Trudeau and Margaret Sinclair Trudeau Kemper. His maternal grandfather, James Sinclair, was also a federal cabinet minister.

Trudeau was born on December 25, 1971, in Ottawa, Ontario. He was only the second child in Canadian history to be born when one of his parents was prime minister; the first was John A. Macdonald's youngest daughter Margaret Mary Macdonald, and Trudeau's younger brothers Alexandre (Sacha) (born December 25, 1973) and Michel (1975–98) were the third and fourth, respectively. Pierre and Margaret Trudeau separated in 1977, when Justin was six years old, and Pierre retired as prime minister in 1984. Of his mother and father's marriage, Trudeau said in 2009, "They loved each other incredibly, passionately, completely. But there was 30 years between them and my mom never was an equal partner in what encompassed my father's life, his duty, his country."
