The first dairy product consumed by humans was fluid milk. While the cow is the major milk producer today, the milk of other mammals (eg, bison, caribou, goat) is widely consumed in some parts of the world. Unquestionably, the first "processed" dairy product made from fluid milk was cheese. It was standard fare in ancient Egypt, Greece and Rome and was frequently used as field rations by ancient armies. In Europe cheesemaking industries were run in monasteries, which produced varieties still made today. In Canada the popular Oka cheese was developed in a Québec monastery.
Canada's modern, highly sophisticated, multibillion-dollar dairy-processing industry began in the early 1600s, when French settlers brought in dairy cattle. For the next 250 years, dairy production remained a farm or cottage industry. As towns and villages were established, fluid milk, butter and cheese were provided by local farmers, a situation that did not change until the 1850s. The modern factory method of cheesemaking was introduced by Jesse Williams, who built the first cheese factory in Rome, New York, in 1851. The first cheese factories in Canada were built in Oxford County, Ontario, in 1864 and at Dunham, Québec, in 1865. About 20 years later, the factory method of cheese production was introduced to Scotland where it was called the Canadian cheese-making system.
By 1873 there were about 200 cheese factories in Canada. In 1873 a group of farmers established the first creamery in Canada at Athelstan, Qué, but it survived for only about 10 weeks. Another creamery, started in Helena, Qué, in the same year, remained in production for about 11 years before being converted to a cheese factory.
The first Canadian company to produce condensed milk was established in Truro, NS, in 1883. Dried milk powder was manufactured for the first time by a company started in Brownsville, Ont, in 1904. In 1900 modern large-scale milk distribution began in Toronto, Montréal and Ottawa; in 1927 homogenized milk was sold in Oshawa, a North American first.
As is the case in a number of other Canadian FOOD AND BEVERAGE processing sectors, the dairy industry has experienced a substantial decrease in numbers of factories. Improvements in road and rail delivery systems, packaging methods and processing techniques permitted dairies to increase dramatically the distribution range of even their most perishable product, pasteurized fluid milk. Consequently, large, modern, centrally located production facilities have been constructed and many small, regional dairy companies phased out. In 1961 there were 1710 dairies; by 1998, 270. Retail distribution of most dairy products has also changed significantly. In the 1940s and 1950s many dairy products were delivered door-to-door; today, consumers buy most dairy products directly from a grocery store and home delivery has disappeared.
Major changes have also occurred in the packaging of pasteurized fluid-milk products. Until fairly recently, most fluid dairy products were in returnable glass containers; now most are in plastic, heat-sealed bags or in rigid containers made from paper laminated with plastic film. Both packaging types have significantly increased the shelf life of liquid dairy products. The latest development in milk packaging is the so-called "aseptic" (sterile) packaging. A totally sterile container is filled with fully sterile milk and sealed in a sterile environment before going to an outside carton-handling line. Fluid dairy products so processed are shelf stable at room temperatures for 6 months or more. The first Canadian aseptically packaged fluid milk was produced by a Montréal dairy in the mid-1960s. After a slow start, aseptic packaging facilities were established in most provinces.
The Canadian dairy manufacturing industry is highly regulated (see FOOD LEGISLATION). It must comply with regulations set by the dairy division of Agriculture Canada, by the Health Protection Branch of HEALTH CANADA, by CONSUMER AND CORPORATE AFFAIRS Canada and by provincial counterpart agencies. The dairy-processing sector is represented by the National Dairy Council of Canada in Ottawa. Total net farm cash receipts from the dairy sector for 1997 stood at $3.8 billion, placing the sector third in agriculture behind grains and red meats. About 81% of Canada's dairy farms are in Ontario and Québec, 14% are in the Western provinces, and 5% are in the Atlantic provinces. In 1998 there were approximately 1.2 million cows in Canada and 22 643 dairy farms producing 79.1 million hectolitres of milk. The primary breeds are Holstein (comprising more than 85% of Canadian dairy herds), Ayrshire, Jersey, Brown Swiss, Canadian, Guernsey, and Shorthorn. During the 1997-98 dairy year, dairy products shipped from approximately 270 processing plants were valued at $8 billion, accounting for 14% of all processing sales in the food and beverage industry. There are approximately 26 000 people working on dairy farms, and almost 20 400 other workers are employed in the plants.
