How many people speech french in the Canadian shield?

The Canadian Shield is a geographic formation in the north central, and slightly eastern area of Canada. If your question is actually how many people speak French and live on or near the Canadian Shield, there are a few, but not many. The majority of French speaking Canadians live either in the Province of Quebec, and the Province of Manitoba. While a reasonably sized chunk of the Shield does lay in Manitoba, it is not the portion of Manitoba that is largely French speaking. That being said, I am French Canadian, and I was born in a small town, right on top of the Canadian Shield :)
