Marine Engineer/Power Engineer, two different animals altogether. To qualify that, I, with a First Class Motor, 4th Class Steam, was assessed here in Nova Scotia as Fourth Class Stationary Engineer and permitted to write for 3rd Class. The assessment from Alberta was for 3rd Class. Each Province has it's own standards and it's own way to assess Marine Certificates. However, if your CoC is Motor, not Steam, it's not worth bothering trying for an assessment.
As regards the exchange of Power Engineer for Marine Engineer, it ain't gunna happen. Power Engineers are Provincially qualified and Marine Engineers are Federally qualified in order to meet international STCW requirements. Division of Federal and Provincial authorities are specified in the British North America Act, 1867, which became the Constitution Act of 1982, sections 92 and 93. Feds cannot meddle in Provincial matters and Trades Education and qualification is Provincial.
