Still , the Queen consented to allow her representatives in Canada to undertake more of her duties , and by the early 1970s it was common practice for the governor general to represent the Queen and Canada abroad on state visits . Elizabeth continued to tour the country , though , and did so a number of times during the 1970s . That which was undertaken in 1970 — involving the Queen , the Duke of Edinburgh , Prince Charles , and Princess Anne — to mark the centennials of the creation of the Northwest Territories and of Manitoba was also intended , by way of the monarch 's presence in Inuvik and Tuktoyaktuk , to assert Canadian sovereignty over the north , which was then being questioned by the United States . In 1973 , the Queen and Prince Philip travelled to Charlottetown to celebrate centennial of Prince Edward Island and to Regina for the 100th anniversary of the establishment of the Royal Canadian Mounted Police . At the same time she , on Trudeau 's advice , attended that year 's Commonwealth Heads of Government Meeting — the first held on Canadian soil — initiating the tradition of the monarch attending such conferences , no matter the location . Three years later , Trudeau also , at the urging of Premier of Quebec Robert Bourassa , advised the Queen to open the Olympics in Montreal , which were attended by no less than six other members of the Royal Family : the Duke of Edinburgh , Mark Phillips , Prince Edward , Prince Andrew , Prince Charles , and Princess Anne , who competed in the games for the United Kingdom . Then , the following year , the Queen , accompanied by her husband , returned to undertake a coast-to-coast circuit marking her Silver Jubilee
