"The federal Conservative party has sent a threatening email to the widow of an asbestos victim in the latest chapter of Canada's debate over the hazardous mineral."

"A top Tory official is warning the woman to stop using the party logo in an online ad campaign against the controversial industry — a campaign she started after her husband died of an asbestos-related cancer.

Michaela Keyserlingk, whose husband Robert died in 2009 of mesothelioma, has been running an online banner since the spring that reads, "Canada is the only western country that still exports deadly asbestos!"

Conservative party executive director Dan Hilton warned Keyserlingk to stop using the Tory symbol immediately."
