Threat of \u2018vehicle ramming attack\u2019 prompted increased Toronto police presence

Toronto police have increased their presence in the city’s downtown core after receiving information about a “potential risk” to the Greater Toronto Area.

CTV News has confirmed that some Toronto police officers were sent a memo saying that a threat was made about a “potential vehicle ramming attack” in the busy CN Tower area.

At a news conference Thursday, police refused to specify what type of information or threats they were investigating, but said that the CN Tower and venues in the surrounding area will remain open.

"Whenever we have report of a potential risk we take that seriously," Acting Supt. Michael Barsky told reporters. "The police presence in this area is simply to ensure that the public can enjoy and come down to this area unimpeded and without any worry."

Emergency Task Force officers were seen near the CN Tower Thursday, while officers on bicycles patrolled the area around the nearby Rogers Centre.

York regional police also tweeted that there will be an increased police presence around the region north of Toronto.

There was also a heavy police presence at Canada's Wonderland amusement park in Vaughan, Ont.

Toronto Mayor John Tory, Ontario Premier Doug Ford and federal Public Safety Minister Ralph Goodale all said that they are monitoring the situation.
