Stephen Harper, Canada's prime minister has released a brief statement
Earlier today there was an attack at the National War Memorial and on Parliament Hill. Our thoughts and prayers are with the families of those who were attacked. The Prime Minister is safe and not on Parliament Hill and being briefed by security officials. The police continue to do their important work and we are still gathering the facts.

What has been reported
According to CBC the Canadian soldier who has been killed was a reservist.
There are conflicting and unconfirmed reports about the number of shooters involved. Journalist Bruce Cheadle reports there were between two and three gunmen, and one was shot by the Canadian parliament's Serjeant at Arms.
The gunman, who was said to be carrying a rifle and wearing a a banadana, reportedly forced a driver out of their car after shooting a soldier and drove towards parliament, where more shots were fired. Reuters cites an eyewitness who claimed the gunman was chased by police into the centre block of parliament with 30 shots being fired inside the building.
CNN quotes Ottawa police spokesperson Marc Soucy who claimed there were "numerous gunmen" but only one person was shot.
Aside from the soldier, CBC Ottawa reports Ottawa has received three patients, two of whom are stable.
Josh Wingrove, a reporter for the Globe and Mail has tweeted he saw a body near the library of Parliament.
What we don't know
It is still unclear how many gunmen were involved, any motivation they might have had, and police have stressed the incident is ongoing.
