The provinces of Ireland serve no administrative or political purposes, but function as historical and cultural entities.

Reference re Agricultural Products Marketing: The marketing of agricultural products has had a turbulent history in Canada.  In 1949, the Parliament of Canada enacted the "Agricultural Products Marketing Act" in order to regulate extraprovincial trade.  By the 1960s, Ontario and other provinces had settled on a model of marketing boards for specified agricultural products, while the federal government started to set up national schemes as with the Canadian Dairy Commission.  Many provinces, but especially Ontario and Quebec, entered into the "Chicken and Egg War" of 1971, where they used their powers to retaliate against each other's products.  This resulted in the passage of the "Farm Products Marketing Agencies Act" by the Parliament of Canada that came into force in December 1972, and the Canadian Egg Marketing Agency was the first scheme to be created on a national scale under it.
