First time doing a Native Fishermen.  What form is applicable T2125? or T777? or T2121? Fisherman has a T4E that shows up on his My CRA Account, also has two T4A's that don't show on his My CRA Account.  Has an ROE that shows income for Fresh Catch for one day, no T4 back up.  What can he claim in expenses?  Any guidance would be helpful.
