Canada used Newfoundland and Labrador's fishery as a bargaining tool with other countries before they drove it into the ground, had that not happened it could be a multi billion dollar industry. The oil and gas industry, which has been around for decades, has sent billions into the federal coffers, workers from the province have been a huge contributor in building Alberta's oil industry. Minerals from Labrador have been sent to northern Ontario to be refined, and Quebec has been able to develop their hydro power thanks to the $1 billion a year they've been making off of Labrador's hydro resources.
