The independent special interlocutor on unmarked graves says “urgent consideration” should be given to legal mechanisms as a way for Canada to combat residential school denialism.
Kimberly Murray made that call in an interim report released Friday, just over a year after she was appointed to an advisory role focused on how Ottawa can help Indigenous communities search for children who died and disappeared from residential schools.
The former executive director of the Truth and Reconciliation Commission of Canada spent much of the past year travelling the country and hearing from different communities, experts and survivors.
The Liberal government created her role as it looked for ways to respond to First Nations from across Western Canada and in parts of Ontario using ground-penetrating radar to search former residential school sites for possible unmarked graves.
In her interim report, Murray raised concerns about increasing attacks from “denialists” who challenge communities when they announce the discovery of possible unmarked graves.
“This violence is prolific,” the report said. “And takes place via email, telephone, social media, op-eds and, at times, through in-person confrontations.”
Murray listed several examples, including after the May 2021 announcement by the Tk’emlups te Secwepemc First Nation that it had discovered what are believed to be 215 unmarked graves at the former site of the Kamloops Indian Residential School.
The findings garnered international media attention and triggered an outpouring of grief, shock and anger from across the country, both in Indigenous and non-Indigenous communities.
Murray said in her report that on top of dealing with an onslaught of media attention, the British Columbia First Nation had to deal with individuals entering the site itself.
“Some came in the middle of the night, carrying shovels; they said they wanted to ‘see for themselves’ if children are buried there. Denialists also attacked the community on social media.”
Kukpi7 Rosanne Casimir of Tk’emlups te Secwepemc First Nation said she no longer uses social media without heavy filters because of the intensity of the “hate and racism” she experienced, according to the report, and believes the issue needs more attention.
Murray said Canada has a role to play to combat this sentiment and that “urgent consideration” should be given to what legal tools exist to address the problem, including both civil and criminal sanctions.
Her interim report also underlined the need for greater access to records, including the highly sensitive documents compiled to adjudicate compensation claims under the Indian Residential School Settlement Agreement. They are set to be destroyed by 2027, as decided by the Supreme Court of Canada.
The records detail the abuses survivors suffered. Survivors are able to request copies of their own records or consent to them being sent to the National Centre for Truth and Reconciliation, the archive designed to house documents from the residential school system.

Murray’s report said only 30 survivors have chosen to have their records preserved.
She said their pending destruction is concerning because they could contain information relating to the deaths and burials of other children.
How ground penetrating radar is used to find unmarked graves at residential schools
Indigenous communities searching for unmarked graves have encountered a rising number of individuals questioning, or outright denying, that children disappeared or died in residential schools, says a new report from an independent special interlocutor.
Ground-penetrating radar is the technology behind the identification of what are believed to be unmarked burial sites, including for the remains of children, on the grounds of former residential schools.
The process gives communities with the first glimpses of physical evidence of possible graves, but it is not well understood.
It is also being used to fuel misinformation about the findings.
The Truth and Reconciliation Commission that investigated the residential school system and its legacy estimated around 6,000 Indigenous children died at the federally funded institutions. The National Centre for Truth and Reconciliation maintains a student memorial register that includes more than 4,000 recorded names. Many experts believe the actual number to be much higher.
Kisha Supernant is the director of the University of Alberta’s Institute of Prairie and Indigenous Archaeology and serves as a member of the federal government’s national advisory committee on residential schools, missing children and unmarked burials.
In a January interview with The Canadian Press, Supernant detailed how ground-penetrating radar works, what its limitations are and what the public should know about the technology.
What is ground-penetrating radar and how is it used?
The basic principle, Supernant says, is that ground-penetrating radar sends an electromagnetic wave into the ground. As the wave travels below the surface it encounters different things and bounces back to the machine.
She says the unit itself looks like a box, roughly the size of a toaster oven, which is usually attached to a cart that someone pushes along the ground.
When her team does searches, they divide the area into a grid and walk a line with their ground-penetrating radar unit. It can be a slow process, Supernant says, depending on the size of the area being searched.
“When we’re using it to try to locate potential unmarked graves, what we’re really doing is we’re sending that signal through the ground and then trying to create a map of what we think we see below the surface.”
She says people should think of the soil as a background signal.
“That’s why you hear terms like `anomaly’ used, because there’s sort of a steady background signal and then something changes and we try to make sense of (what) that change might represent.”
Supernant says there are methods for figuring out what an anomaly might be. And certain objects, like rocks or metal, have distinct signatures.
When it comes to finding unmarked graves, what they are looking for is a grave shaft.
“When you dig a grave, you disturb the soil, and ground-penetrating radar can sometimes detect that change in the soil from the digging of the grave itself.”
There are sets of signals often associated with graves, either marked or unmarked, she said.
Supernant says her team is also guided by elder testimony and community knowledge to help identify where to search, as the areas where graves may be no longer have markers.
What technology can - and cannot - tell us
First Nations communities tend to use careful language when announcing the findings of such searches, ranging from anomalies and areas of interest to possible graves.
“We use the careful terminology because at the end of the day, ground-penetrating radar alone cannot 100 per cent confirm that there is a grave present or that there’s anything in that grave,” Supernant said.
She says to confirm the existence of graves, searchers can rely on old aerial photographs of an area to show whether it was a cemetery, or collect information from archival records held by churches and other institutions.
In terms of physical evidence, Supernant says there can sometimes be impressions left on the land itself, but in order to confirm the existence of remains, “you need to do something below the surface.”
That’s why First Nations that have detected possible unmarked graves are exploring the possible options. Many communities are hoping to avoid disturbing the sites even more.
Supernant says some methods being considered include trying to sample the soil to test for the presence of human DNA.
“That still is invasive, but it’s a lot less invasive than digging down.”
What do people get wrong about ground-penetrating radar technology?
Supernant says there are two main misconceptions about the technology and its role in searches: “On the one hand there’s an overstatement, and then on the other hand, there’s an undermining.”
In May 2021, the Tk’emlups te Secwepemc Nation announced it had detected 215 possible unmarked graves at a former residential school in Kamloops, B.C. Supernant says some people were left with the impression that 215 children’s bodies had been found.
“Ground-penetrating radar can’t do that.”
But because some assume that ground-penetrating radar can do more than it can, a narrative has formed where those anomalies or possible graves have “become children.”
She says she understands why that happens, because the announcements are devastating and people want to find the children who went missing from residential schools.
On the other hand, Supernant says she also sees people trying to downplay the results, by “using the ambiguity that is inherent in the technology and that we can’t know for sure to really discredit it entirely.”
“It’s also really dangerous because we do know how to distinguish a rock from a potential grave. But sometimes when denialists get a hold of some of these narratives, they use that to undermine.”
She says that’s not true, as there is established science behind the technology.
