Montreal - Four Canadian government ministers were sent envelopes of a suspicious white powder on Thursday that was later believed to be harmless, police said.
"In each case, a staffer found white powder in an envelope" at the ministers' Quebec regional offices, provincial police Sergeant Richard Gagne told AFP.
The envelopes were delivered to the constituency offices of Infrastructure Minister Denis Lebel, International Development Minister Christian Paradis, Minister of State for Small Business and Tourism Maxime Bernier and Public Safety Minister Steven Blaney.
