UPDATE: Canadian killed in London terror attack, Trudeau confirms

Prime Minister Justin Trudeau said a Canadian was among those killed in Saturday night's terror attack in London.

In a written statement released Sunday, Trudeau added the government will not be commenting further out of respect for the family.

Late Sunday afternoon, however, it was learned a woman from British Columbia, Christine Archibald, was the Canadian killed in the London tragedy.

Her family in Castlegar, B.C. released a statement through the federal government saying Archibald had been working at a homeless shelter until she moved to Europe to be with her fiance.

Her age was not given.

Earlier, the High Commission of Canada in the United Kingdom confirmed that a Canadian was "directly impacted'' by the attack.

The Canadian government has advised citizens to be vigilant in the wake of the attack.

The government and diplomats on the ground in London advised travellers to avoid the affected areas, follow the instructions of local authorities and monitor local media.

The following is the PM's full statement following the London tragedy.

"Canada strongly condemns the senseless attack that took place last night in London, United Kingdom, which killed and injured many innocent people. I am heartbroken that a Canadian is among those killed.

"We grieve with the families and friends of those who have lost loved ones, and wish all those injured a speedy and full recovery.

"Londoners and people across the United Kingdom have always displayed strength and resilience in the face of adversity. We recently witnessed this after the attacks in Manchester and in the Westminster area of London. This time will be no different.

"These hateful acts do not deter us; they only strengthen our resolve. Canadians stand united with the British people. We will continue to work together with the United Kingdom and all our allies to fight terrorism and bring perpetrators to justice.

"The Government of Canada will not comment further at this time out of respect for the family."
