Harry William Hays, PC (December 25, 1909 – May 4, 1982) was a Canadian politician and Cabinet minister in the government of Lester Pearson.
Born in Carstairs, Alberta, Hays had several careers related to agriculture. He was an auctioneer, rancher and breeder as well as a radio broadcaster. He was a founding member and president of the Alberta Poultry Breeders' Association and also served as president of the Alberta Holstein Breeders' Association. He led the Canadian Swine Breeders during World War II when it initiated the "Bacon for Britain" campaign of increased production as part of the war effort. In the 1950s, he pioneered exporting cattle by airplane allowing the Canadian industry to develop new markets in Mexico and the United Kingdom.
Hays sold his dairy herd in 1959 in order to devote time to politics, becoming the 27th Mayor of Calgary. He was recruited by Lester Pearson to run for the Liberals in the 1963 federal election and was the only Liberal MP elected in Alberta or Saskatchewan. He became the Member of Parliament for Calgary South and was immediately appointed Minister of Agriculture. Hays was often absent from the House and initially continued to serve as Calgary's mayor after his election to parliament. He also continued his work as an auctioneer as well as his volunteer duties for the Rotary Club.
Hays had little formal education and was popular for his down to earth manner of living and talking and often swore and used poor grammar and colourful expressions. He described his agricultural policy by saying "We want a flush-toilet, not an outhouse, farm economy for Canada". However, some of his views were unpopular with farmers, such as his opposition to farm subsidies. He advocated a minimum guaranteed income for farmers and a system of marketing boards. During his tenure as minister the Dairy Commission Act was introduced establishing an agency to purchase, store and market dairy products. He was also responsible for the Farm Machinery Syndicate Credit Act which extended loans to farmers to buy machinery co-operatively. Journalist Walter Stewart once wrote of Hays that "No minister seems more inept inside Parliament and few get so much done outside it."
