What parts of canada appear to have relatively few resources?

One part of Canada that has relatively few resources and is considered a 'have-not' area is the Maritimes ie New Brunswick, Nova Scotia, and PEI. While there have been some exceptional mines like the zinc Brunswick Mine in New Brunswick and the Cape Breton coal mines in Nova Scotia these are the exceptions. Compared to say British Columbia and Ontario where there are many significant metallic mines like Highland Valley Copper and Copper Mountain and the ex Kimberley Mine and Ontario with mines like Sudbury nickel and the silver at Cobalt and the Kidd Ck Mine at Timmins they just don't have a large number of significant mines. Also BC and Ontario have significant forest resources.
