OTTAWA - The Canadian government determined to return to business as usual on Thursday after a reported convert to Islam shot dead a soldier at the National War Memorial and rampaged through Parliament before being killed himself.
Employees began returning to the Parliament Hill complex amid tighter security. The House of Commons was set to open on schedule at 10 a.m. (3 p.m. BST), with Prime Minister Stephen Harper speaking at that time.
"This sends a clear message of Canada's resolve to maintain its free and democratic way of life," House Speaker Andrew Scheer said in a statement.
The flag flying over Parliament's Centre Block, where the gunman had burst in on Wednesday morning, was at half mast.
Members of Parliament said they would gather at the War Memorial, near the parliament, to honour Canadian soldier Nathan Cirillo who was shot at the site.
Parliament Hill and the downtown core were under lockdown for 10 hours on Wednesday as police scoured the area for more possible suspects.
"There was only one gunman," said a Royal Canadian Mounted Police officer who was guarding Parliament Hill on Thursday morning, checking the identity cards of workers and media going into the parliament complex.
He said in the confusion on Wednesday morning, witnesses saw things from different angles, suggesting the possibility of second shooter but videos and further interviews showed this was not the case.
The killing of the Canadian soldier was the second this week with a possible link to Islamist militants.
In a brief address to the nation on Wednesday night, Harper pledged to redouble the country's fight against "terrorist organizations.
"Let there be no misunderstanding, we will not be intimidated. Canada will never be intimidated," he said.
"This will lead us to strengthen our resolve and redouble our efforts and those of our national security agencies to take all necessary steps to identify and counter threats."
A convert to Islam on Monday ran over two Canadian soldiers with his car, killing one, near Montreal.
Both attacks took place after Canada announced this month it would send six jets to take part in air strikes against Islamic State fighters who have taken over parts of Iraq and Syria.
Harper said Canada would now "redouble our efforts to work with our allies around the world and fight against the terrorist organizations who brutalize those in other countries with the hope of bringing their savagery to our shores".
Defence Minister Rob Nicholson said Canada's deployment to Iraq would go on unimpeded.
