Top Active Gold Mines
in Canada

Detour Lake is one of the largest gold mines in Canada and a cornerstone asset for Agnico Eagle, acquired through its 2022 merger with Kirkland Lake Gold. The open-pit mine sits along the Sunday Lake Deformation Zone and has measured and indicated resources totalling 17.2 million ounces of gold.

Macassa is one of Canada's highest-grade gold mines, with proven and probable reserves averaging 7.77 grams per tonne — totalling 2.2 million ounces across 8.8 million tonnes. The mine has operated in the Kirkland Lake camp since 1933 and remains a backbone of Agnico Eagle's Ontario portfolio.

Côté Gold is Ontario's newest large-scale gold mine, having achieved commercial production in mid-2024. The open-pit operation sits on one of the largest undeveloped gold deposits in Canada. In its first full year, the mine produced 279,900 attributable ounces, hitting the top end of guidance.

Alamos Gold's Island Gold District combines the high-grade underground Island Gold mine with the adjacent Magino open-pit operation, producing 250,400 ounces in 2025. Island Gold consistently delivers some of the best underground grades in the country.

Red Lake is one of the most storied gold camps in Canadian history, with over 30 million ounces produced since the 1930s. Evolution Mining acquired the operation from Newmont in March 2020 for $375 million and operates three underground mines and two processing plants on a single integrated site.

Canadian Malartic was once the largest open-pit gold mine in Canada, producing over 700,000 ounces annually at peak. In 2023, Agnico Eagle completed the transition from the exhausted open pit to the high-grade Odyssey underground mine beneath it. The Odyssey project accesses three underground zones — Odyssey South, East Gouldie, and East Malartic — with combined reserves of 5.4 million ounces.

Éléonore is a remote fly-in underground gold mine located in the James Bay region of northern Quebec, approximately 800 kilometres north of Montreal. The mine has been in production since 2015 and processes approximately 7,200 tonnes of ore per day.

Goldex is a mechanized underground mine near Val-d'Or that has been producing since 2008. Known for its low operating costs, the mine extracts ore from the Deep 1 and Akasaba zones and processes approximately 8,700 tonnes per day.

Brucejack is one of the highest-grade gold mines in the world, located in B.C.'s Golden Triangle. The underground mine processes ore from the Valley of the Kings deposit through a 3,800-tonne-per-day mill accessible only by air and a 70-kilometre road from tide-water at Stewart.

The Meadowbank Complex sits 70 km north of Baker Lake in Nunavut and includes the original Meadowbank mine and the satellite Amaruq open-pit deposit connected by an all-weather haul road. All ore is processed through a single 11,000 tonne-per-day mill. Agnico Eagle employs roughly 2,300 workers on site, making it one of the largest private employers in the territory.

Eagle Gold was the Yukon's largest gold mine and one of the few heap leach operations in northern Canada. On June 24, 2024, a catastrophic failure of the heap leach pad sent approximately 280 million litres of cyanide-laced solution cascading into the surrounding watershed. The failure triggered a territorial environmental emergency and forced Victoria Gold into receivership.
