Today is Canada Day, of course, but it used to be known as Dominion Day.
The March 19 1953 edition of the Globe and Mail reported on a Liberal MP who objected to the name Dominion Day, but was rebuffed:
According to the Wikipedia entry on Canada Day, Mr. Côté first tried to get the name changed in 1946 in a private member’s bill. The bill was stalled in the Senate, which recommended that the name be changed to “The National Holiday Of Canada”, which was understandably rejected. He tried several times after that, and was rejected each time; the 1953 attempt might well have been his last, as he died of a heart attack in 1954 at the too-early age of 51.
By the early 1980s, many Canadians were using the term “Canada Day”, and the name was officially changed on October 27, 1982. Future prime minister Stephen Harper introduced a private member’s bill in 1996 calling for a return to the old name; it was defeated.
