People in Castlegar, B.C., held a vigil Sunday evening for a woman killed in last week's attack on London Bridge.

Christine Archibald, 30, originally from Castlegar, was on a weekend trip to London with her fiancé when a group of men attacked a crowd of people on the bridge using a van and later stabbed others in a nearby market.

Archibald was one of eight people who died as a result of the attack.

"It's about community healing," said Castlegar city Coun. Deb McIntosh, who helped organize the event. "It's about letting people who are going through a hard time know that their community cares and that together we can get through just about anything."

About 300 people gathered in the sun at Millennium Park for the vigil, which was being planned before the London attacks to commemorate the recent deaths of other high-profile community members.

The news of Archibald's death added renewed urgency to the event

McIntosh said Castlegar is a caring, compassionate community. She volunteers at the local food bank in Castlegar, and said she's seen several donations made in Archibald's honour.

In a statement released shortly after her death, Archibald's family encouraged people to honour her memory by giving back to their communities, and to, "Tell them Chrissy sent you."

The movement gained traction on social media around the world under the hashtag "#chrissysentme."

"It's gone global, really. And what a wonderful thing to have someone who has passed to have a long living legacy behind them," McIntosh said.

"Death is forever and it's hard-hitting and communities need to recover. And the only way to do that is by coming together and showing love and respect and kindness for one another."
