CALGARY -- A vigil meant to draw awareness to and remember the children whose remains were found at a former residential school in Kamloops, B.C., drew hundreds of people to Calgary city hall Saturday evening.

The event, organized by, took place at 9 p.m. and was aimed at allowing the residents of Calgary a time to reflect on the tragedy that was unearthed last weekend at the site of the Kamloops Indian Residential School.

The remains of 215 children were discovered through the use of ground-penetrating radar. Officials say the school, which opened in 1890, was the largest in Canada's residential school system.

The building was closed in 1978.

Organizers of Calgary's vigil say they also wanted to honour all of the families who were impacted and grieve and pray together.

"There is no way that any scholarly professors, politicians, can say that this is cultural genocide – I don't ever want to hear that again," said Kelly McGillis.

"This is genocide. And if you think about it there were 130 residential schools and in one school – that is a concentration camp."

Following the vigil, officials with the City of Calgary confirmed that the flags at all municipal buildings would be lowered, taking part in the same initiative along with many other major Canadian cities.
