That's because our industry uses only frozen salmon.
I am going to continue in French, because my English is not good enough.
Processing requires purchasing frozen raw materials for reasons involving bacteria and quality control. Canada produces mostly fresh salmon that is sold in restaurants and groceries. However, industrially we almost all use frozen salmon only. Canada does not produce any but we would be very interested if the industry were to develop that niche.
They are two completely different markets. In the fresh product market, salmon is paid for immediately. Salmon is stored and sold much later in the frozen product market. Norway and Chile have developed expertise in that area. We would like Canada to step up. Buying Canadian products would be preferable for us.
