Niagara Falls will light up in orange tonight in honour of the 751 unmarked graves discovered at the site of a former residential school earlier this week.  

The Niagara Falls Illumination Board will be illuminating both the Canadian Horseshoe and American Falls on Friday night, from 10:15 to 11:15 p.m., following the tragic discovery at the Marieval residential school in Saskatchewan.

The falls were previously illuminated in orange on May 30 in memory of the 215 Indigenous children discovered in a mass grave at a former residential school in Kamloops, British Columbia.

"With the possibility that more of these tragic discoveries may occur in the weeks and months ahead, the Niagara Falls Illumination Board is exploring options to best recognize and honour the victims moving forward," says the board.

Meanwhile, in Toronto, the CN Tower will also light up in orange on July 1 in solidarity with Indigenous communities in mourning across Canada.

This comes amid growing calls for Canada Day celebrations to be cancelled altogether in light of these horrific discoveries and for July 1 to instead serve as a day to reflect on the shameful history of the residential school system.
