A northern Ontario New Democrat is raising the issue of mine safety in Ontario mines. Mike Mantha, of Algoma Manitoulin, says the liberals need to take action on this issue. Mantha was reacting to the seventh mining death in the province this year. A 38-year-old miner died in a Thunder Bay mine just over a week ago. The NDP want the majority liberal government to hold an inquiry into mining deaths instead of simply reviewing health and safety.
