TORONTO - Toronto's chief of police says officers in the country's largest city will be more visible today as a result of this week's attacks on soldiers in Ottawa and Quebec.
At the same time, Bill Blair says there is no known specific threat.
Blair says the aim is to reassure people who are obviously concerned at what has happened.
He calls it a "difficult day" for Canada.
Police in Ottawa say a soldier at the National War Memorial was fatally shot today, and a suspect was later shot dead in Parliament's Centre Block.
On Monday, a man ran down two soldiers south of Montreal, killing one of them.
"There is no known credible threat here in the city of Toronto but it is a very busy day," Blair said at a news conference.
"But we will always err on the side of caution."
Police would be more visible at public buildings, such as the legislature, transit facilities and some consulates.
