Borden’s Milk absorbed the operations of the Hamilton Dairy Company in 1930.

In the late 19th century, commercial milk was unhygienic and often diluted with water, chalk or other unsavoury materials. Pure milk became an important health issue.

One of the most important and necessary commercial industries in the community is the well-conducted dairy.

One of the leaders of the pure-milk movement was Hamiltonian Adelaide Hoodless. Her youngest child reportedly died as a result of drinking impure milk. Working primarily through the Hamilton YWCA, Hoodless pushed for educational programs to promote nutrition and sanitation. In an age when women were still rarely involved in politics, Hoodless became a major national advocate for domestic science courses, public health measures, pure-milk legislation and a variety of other issues.
