Canadian Seafood Question

I would like to stop buying those farm raised seafood from Asia like Basa and Tilapia. What are the availability of Canadian seafood in Ontario during Spring time? I got some PEI mussels and Ontario pickerel recently. Are the Haddock and Cod from Canada?

I've seen Canadian coldwater shrimps available before but unlike farm raised shrimps from Thailand/India ,they are not widely available.
