Police killer Harry Roberts is to be released from prison after more than 45 years behind bars.
Roberts, now 78, was handed a life sentence for the murder of three policemen in Shepherd's Bush, west London, in 1966. His 30-year minimum tariff expired 18 years ago.
The Parole Board is understood to have approved his release and he will be subject to close monitoring by police and the Probation Service.
Detective Sergeant Christopher Head, 30, Detective Constable David Wombwell, 25, and Pc Geoffrey Fox, 41, were shot dead without warning while questioning three suspects in a van on August 12, 1966.
A Ministry of Justice spokesman said: "We do not comment on individuals.
"The release of life sentence prisoners is directed by the independent Parole Board once they are satisfied they can be safely managed in the community. Once released they are subject to strict controls for as long as their risk requires them. If they fail to comply with these conditions they can be immediately returned to prison.
"Offenders managed through Multi Agency Public Protection Arrangements (MAPPA) are monitored and supervised by probation, police and other agencies."
Canada's minister of industry James Moore has tweeted that parliament will sit as scheduled on Thursday.
Ottawa Police have lifted some safety blockades which were imposed after a soldier was killed and a gunman shot dead in Parliament.
Parliament Hill and several buildings in and around Ottawa were put on lockdown after a gunman opened fire at the National War Memorial and inside the Hill.
The police said in a statement: "The ongoing police investigation in the downtown core has determined that there no longer exists a threat to public safety in the area.
"However, the police operation continues on Parliament Hill and as such the Hill continues to be off limits to the public."
Canada will not be intimidated by the "despicable attacks" that killed two soldiers this week, Prime Minister Stephen Harper has said.
Addressing the nation following the shooting of a soldier on Parliament Hill in Ottawa, Mr Harper said: "Today our thoughts and prayers are with the family and friends of Cpl Nathan Cirillo.
"Cpl Cirillo was killed today murdered in cold blood as he provided a ceremonial honour guard at Canada's National War Memorial."
He praised the emergency services and members of the public for their actions.
Canadian Prime Minister Stephen Harper has said the country will not be intimidated by the two attacks this week.
He said: "Let there be no misunderstanding. We will not be intimidated. Canada will never be intimidated.
"In fact 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 and keep Canada safe here at home."
He added that Canada would continue to work with its allies around the world to fight against the terrorist organisations "who brutalize those in other countries with the hope of bringing their savagery to our shores".
"They will have no safe haven," he added.
A man jumped the White House fence on Wednesday and was attacked by Secret Service dogs before being arrested, a Secret Service spokesman said.
"Dogs got him," the spokesman told Reuters, referring to the intruder.
Video showed Secret Service agents surrounding the man on the north lawn of the White House, which was put on lockdown.
It comes after an intruder armed with a knife scaled the White House fence and made it inside.
"The individual was immediately taken into custody on the North lawn of the White House by Secret Service Uniformed Division K-9 teams and Uniformed Division Officers," the spokesman said.
K-9 refers to the team using specially trained dogs.
The man was then transported to a local hospital for evaluation, the spokesman said.
The incident comes after an intruder armed with a knife scaled the White House fence and made it inside in September, raising questions about security levels and spurring the resignation of then-Secret Service Director Julia Pierson.
