OTTAWA, July 12 (Xinhua) -- Police have increased their presence in downtown Toronto after receiving information about a "potential risk" to the Greater Toronto Area, CTV reported Thursday.
CTV confirmed that a draft memo was sent to some Toronto police officers saying that a threat was made about a "potential vehicle ramming attack" in the busy Canadian National Tower area.
Emergency Task Force officers were seen near the tower on Thursday while police officers on bicycles patrolled the area around the nearby Rogers Centre.
At a news conference Thursday afternoon, police refused to specify what type of information or threat they were investigating, but said that the tower and venues in the surrounding area will remain open.
York regional police 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, Ontario.
Toronto Mayor John Tory, Ontario Premier Doug Ford and Canadian Public Safety Minister Ralph Goodale all said they are monitoring the situation.
