Modern Canadian ships sent to the War of 1812

How would Canada's three cruisers and Tribal-class destroyers from 1948 affect the War of 1812 if sent back in time?

Their weapons would be overwhelming locally, but without suitable fuel, ammunition, and maintenance they would soon become static batteries rather than a sustainable fleet.

Coal-fired machinery might be supplied poorly with improvised local coal, while the 1812 economy could not sustain oil-fired ships. The Canadian ships could dominate a Great Lakes position until their ammunition and fuel ran out. The scenario therefore gives them overwhelming local weapons without the industrial base to sustain a fleet. Their arrival would not by itself allow a prolonged campaign or an expanded frontier.
