The Canadian Amateur Championship, begun in 1895, is the men's amateur golf championship of Canada. It is staged annually by the Golf Canada. It was played at match play until 1968, went to stroke play beginning in 1969, and reverted to match play in 1995. It returned to stroke play in 2008.
The Royal Canadian Golf Association was founded in June 1895, at a meeting held in Ottawa by ten charter member clubs, hosted by the Ottawa Golf Club (later the Royal Ottawa Golf Club), and the new organization was granted the prefix 'Royal' in 1896. In conjunction with the meeting, the first men's amateur championship was staged, at match play, with the Governor General, Lord Aberdeen, donating a trophy, the Aberdeen Cup, to the champion. Thomas Harley of Kingston, Ontario won the first championship.
This makes the Canadian Amateur slightly older than the U.S. Amateur, which was first staged later in 1895, and hence the third oldest national amateur championship in the world, after the British Amateur Championship, which began in 1885, and the Australian Amateur in 1894.
The Aberdeen Cup was granted in perpetuity to George Lyon, after he won three straight titles from 1905 to 1907. The original cup was retained by Lyon, but was eventually lost. A new trophy was then provided, the Earl Grey Cup. Lyon would win a total of eight Canadian titles, which is still a record, and he also won the gold medal at golf in the 1904 St. Louis Olympics.
The tournament was held annually until 1914 inclusive, but then was cancelled from 1915 to 1918 because of World War I. It resumed in 1919, and then was staged annually until 1939 inclusive, being cancelled again from 1940 to 1945 because of World War II. It has been held annually since 1946.
