Continuous improvement

Metro encourages its suppliers of wild and farmed seafood products to follow a continuous improvement process, by favoring those who make tangible progress toward the sustainable management of their activities.

List of "continuous improvement" products:

Farm-raised salmon

Metro will seek out suppliers with good farming practices that minimize environmental impacts, such as standardized environmental management systems, integrated farming practices and enclosed tanks, while producing a top-quality product.

Tropical shrimp

Shrimp farms in Asia have been targeted for their harmful impacts on mangrove swamps. Therefore, Metro will seek out suppliers that use responsible practices, and standardized environmental management and traceability systems (e.g. the Best Aquaculture Practices (BAP) logo).


Canadian and U.S. Atlantic haddock stocks have been improving over the past several years. However, we will continue to seek out suppliers that show proof of continuous improvement in terms of fishing techniques (e.g. use of selective nets to avoid the bycatch of cod).


Longline swordfishing (using a long fishline with multiple baited hooks) involvessignificant problems of bycatch (sharks, turtles and sea birds). As such, Metro will seek out fisheries that use sustainable fishing techniques, such as harpoon, or longlines accompanied by an improved monitoring system to decrease bycatch.

Atlantic and Greenland halibut

These species, which are regulated by government quotas, are faring well but are still sensitive in Canada (risk of overfishing). Certain techniques also involve the risk of bycatch. As a result, Metro will promote selective techniques to traditional Canadian fisheries.

Scallops and Stimpson's surf clam

For these shellfish species, the problem lies in the fishing technique (bottom dragging) and its impact on the seabed biodiversity. Metro will seek out fisheries with the best dragging techniques (e.g. a Canadian fishery that is MSC certified for scallops) or more sustainable solutions, such as farming or hand-harvesting.
