I think there is a reference in one of the Mint Reports that Winnipeg would be used as an optional location for creating loonie blanks. Most loonie blanks in the 2000s I think were made by Jarden. Winnipeg blanks would be brass plated steel instead of bronze plated steel, since Winnipeg uses a more environmentally friendly process.
