Aristide Blais FRCS (October 18, 1875 – November 10, 1964) was a Canadian physician and Senator.

[1] Early in his medical career, Blais partnered with French-Canadian physician and Senator Philippe Roy in practice.

[3] During the World War I Blais served as a captain in the Canadian Army Medical Corps, later promoted to lieutenant-colonel, and was appointed in charge of the No.

Blais publicly noted his appointment to the Senate was a tribute to French Canadians in Alberta, and a fulfillment of former Prime Minister Wilfrid Laurier's promise upon Alberta entering Confederation in 1905, that French Canadians in the province would always have a Senate representative.

[3] Blais served until his death on November 10, 1964, at 89 years of age, at Shaughnessy Military Hospital in Vancouver, British Columbia.
