Tuna cans are labeled for sale within 5 years. As for actual practice, we don't know how long it will last because we haven't been canning it long enough for them to spoil (assuming you protect the cans from corrosion.) It probably won't taste as good and might be an odd color, but it will be safe to eat if the can is intact and not dented/bulging.
