CRA considers that a partnership with functional currency partner must file T5013 return and slips with it in the functional currency

Where one or more of the partners of a partnership has made a functional currency election, CRA considers that the partnership must file its T5013 return and slips with CRA in the elected functional currency. “Separate T5013 slips in Canadian dollars must be prepared by the partnership and provided to the non-electing partner(s) but these slips are not to be filed with the Canada Revenue Agency.”
