Some 70,000 people born in Canada were living in Britain at the 2001 Census � up slightly from 1991.
London dominates the figures, but Scotland also makes an appearance � the nation was a source for emigration to English-speaking Canada.
Many young Canadians have found it easier to come to Britain over the years because visa rules favoured people from the old Commonwealth nations with either a parent or grandparent born in the UK.
Young Australians, New Zealanders and South Africans have taken advantage of the same rule to enter.
