G.S. Dunn expands Bow Island mustard mill with $30M investment and Alberta tax credit

Oct 10, 2025 | 4:30 AM

A $30-million expansion by G.S. Dunn Limited is growing the mustard milling company’s presence in Bow Island, backed by a $3.1-million tax credit from Alberta’s government.

The investment has created 34 new jobs, opened access to two new international markets in Japan and South Korea, and significantly boosted the company’s demand for raw mustard seed—from $13 million to $44 million annually, all sourced from western Canada.

The expansion is supported through the Agri-Processing Investment Tax Credit (APITC), a provincial program that offers a 12 per cent non-refundable tax credit for investments of $10 million or more in value-added agri-processing projects in Alberta.

“Investors continue to choose Alberta as a place to establish roots, grow and expand because it makes good business sense,” said RJ Sigurdson, minister of agriculture and irrigation.

“The Agri-Processing Investment Tax Credit is just one of the ways our government commits to creating ideal conditions for businesses while attracting investment, diversifying the economy, and creating more jobs for Albertans.”

The Bow Island upgrade marks the second phase of G.S. Dunn’s value-added mustard milling project in the region.

Since its initial entry into Alberta, the company has increased processing capacity by more than 200 per cent.

The latest phase alone has boosted output by roughly 70 per cent compared to pre-expansion levels.

“We are proud to announce the successful completion of our new mustard mill in Bow Island,” said Daniel Boullion, chief financial officer for G.S. Dunn Limited.

“This state-of-the-art facility stands as a testament to the collaborative efforts of the provincial government, the Town of Bow Island, local construction firms, and our dedicated workforce,” he added.

“We look forward to continuing to strengthen the agri-processing industry in southern Alberta together with our local mustard grower partners.”

G.S. Dunn, headquartered in Hamilton, Ont., is the world’s largest supplier of value-added milled mustard, offering more than 250 products to 130 customers in over 70 countries.

The company purchased the former Spitz sunflower seed plant in Bow Island in 2019, converting it into a mustard milling facility.
