In the early days of the paper sack industry in Canada, there were a few small companies producing sacks for local markets. The first paper sack mill in Canada was established in 1883 in Montréal. By the early 1900s, there were several mills operating in Québec and Ontario. The Canadian paper sack industry really took off in the 1920s, when new technologies and an expanding economy led to increased demand for paper sacks. Mills were established across the country, from British Columbia to Nova Scotia. Today, the paper sack industry is an important part of the Canadian economy, with over 30 mills employing more than 1,500 people.
