Ayre & Sons, Ltd. was a department store chain in Newfoundland, Canada.

Ayre opened his flagship store on Water Street in St. John's in 1859.

After Newfoundland joined the Canadian confederation in 1949, Ayre's opened some more stores across the province in the 1960s, with locations in Mount Pearl, Carbonear, Corner Brook, and Wabush.

However, the company began to encounter financial problems in the 1980s, and in 1991, Ayre and Sons filed for bankruptcy.

Following the sale of Dominion to A&P Canada, the Dominion stores in Newfoundland and Labrador were resold to local owners in 1987 and subsequently merged with two smaller local chains.
