Quebec TP1000

New senior Quebec client. Her daughter (also QC resident) has POA which was sent to Revenu Quebec last year. (I also have a copy). She wants to sign for mother.
Unlike MR-69, AuthRep & T183 the Quebec TP1000 doesn’t have any line or checkmark to indicate the document was signed by the POA.
Wonder if Revenu Quebec would accept such.
