On November 11, 1916, the Duke of Devonshire became Governor-General of Canada.
During his time in office, the Canadian government introduced conscription; the women’s suffrage movement grew in strength, and as a result, women were given the right to vote; and there was also the great Winnipeg General Strike.
Because of his experience as an agricultural land owner in England, he had a keen interest in agricultural issues in Canada. The Duke of Devonshire Trophy for the Ottawa Horticultural Society was established in 1921. Another great achievement was to set up of experimental farms, including the Government of Canada’s major experimental farm in Ottawa, Ontario.
