Is It Safe To Freeze Canned Salmon? - Tasting Table
Briefly

Canned fish, especially salmon, is not only versatile and protein-rich but can also last for years when stored properly, making it a convenient kitchen staple.
When freezing canned salmon, it is essential to transfer it from its can into an airtight, freezer-safe container to maintain its quality and safety.
If you think you won't use cooked canned salmon in a few days, freezing is the best option, allowing it to last up to three months.
To thaw frozen salmon safely, the best method is to move it to the refrigerator a day in advance to ensure it thaws evenly.
