The National Day for Truth and Reconciliation, originally and still colloquially known as Orange Shirt Day, is a Canadian holiday to recognize the legacy of the Canadian Indian residential school system.

The Canadian Indian residential school gravesites refer to the allegation that there are hundreds or thousands of child graves hidden on the grounds of Canadian Indian residential schools. On 27 May 2021, the Kamloops Indian Band issued a press release which stated that ground-penetrating radar had given 'confirmation' of the presence of 215 undocumented child graves on the grounds of the former Kamloops Indian Residential School. This announcement led a scandal, with news media outlets, both within Canada and internationally, reporting 'mass graves' at the school. Several similar reports from other former residential schools followed over the ensuing months, leading to commemorations and protests. In the ensuing months, a series of suspicious fires were set at Catholic churches, and Pope Francis made a "penitential" visit to Canada in 2022.
