William Neilson Dairy Limited is a Canadian dairy company owned by Saputo Inc. The company is based in Toronto, Ontario. In the United States, its products are sold under the name Neilson. Its products are sold at Walmart, Loblaws, Real Canadian Superstore, Giant Tiger, and Fortinos, among others.
The company was founded by William Neilson (1844–1915) in 1893 as one of many independent dairy producers in Canada. Neilsons began as a milk retailer, and then switched to cream and ice cream products.
Neilson Dairy became William Neilson Limited in 1907. After the mid-20th century, many smaller companies were taken over by larger corporations. William Neilson was sold to George Weston Limited in 1947.
Neilson Dairy became part of the Saputo corporate group after George Weston Limited sold the dairy unit in 2008.
