The story
The Canadian federal government has been active in supporting the dairy industry since 1890, when the first Dominion Dairy Commissioner was appointed.
In 1967 the government of Canada passed the Canadian Dairy Commission Act which established the Canadian Dairy Commission (CDC).
The Canadian Milk Supply Management Committee, whose members include the CDC and representatives of provincial producer marketing boards, was set up in 1970 to administer the national Market Sharing Quota.
In 1972, the Farm Products Agencies Act authorized the establishment of supply management, which can restrict production by use of quotas.
