The bomb squad is on the scene on Main Street West after reports of a possible explosive in a white plastic garbage bag in front of the Bank of Nova Scotia.
A robot working for the bomb squad is poking at the bag.
City fire and police crews have blocked the area from Simms Corner along Main Street to the corner of Church Street and Manawagonish Road.
We are told it will be closed until 6pm tonight.
The call came in this morning about 11:45 at which time tenants, shoppers and employers along Main Street West were evacuated.
