Ontario health agency reports major data breach to watchdog without notifying patients

Government and privacy officials are investigating a potential data breach involving the health data of hundreds of thousands of patients who have not yet been notified about an incident in the spring.
On Friday, Ontario Premier Doug Ford, Health Minister Sylvia Jones and the Information and Privacy Commissioner (IPC) all appeared to confirm that the data of patients using the Ontario Health atHome service may have been breached.
In a letter to Ontario Liberal MPP Adil Shamji, who first flagged the potential cyber attack, the IPC suggested he was correct when he said the incident occurred more than three months ago in March.
The IPC commissioner confirmed to Shamji that a report had been filed “that aligns with the circumstances and date described in your letter.”
Shamji had said the breach happened on or around March 17 and involved 200,000 patients.
A spokesperson for the IPC told Global News the watchdog had received reports of a breach from Ontario Health atHome — which did not report it until the end of May. The government didn’t confirm the breach until June 27, after questions at an unrelated news conference.

“Ontario Health atHome notified our office of a privacy breach on May 30, 2025,” the spokesperson wrote. “At this stage, we are reviewing the circumstances of the incident and cannot share further details at this time.”
Jones said the public agency responsible was investigating.
“Ontario Health is absolutely investigating right now,” she said. “We have a division that focuses on any potential cyber breach, and as is standing operating (procedure) Ontario Health and Ontario Health atHome will notify if there has been any form of breach to individual patients, but that investigation is going on right now.”
With the breach potentially occurring in March and the IPC notified last month, it is unclear why patients potentially involved have not yet been notified. Shamji said they should have been notified long ago.
“I fundamental tenet of a breach of this nature — especially involving so many people — is to immediately notify those individuals,” he said. “They need to know that their personal information may be compromised and that they need to be monitoring things like credit scores.”
Ford appeared to suggest his office had not been informed, despite Ontario Health atHome telling the IPC about the breach a month earlier.
“We’ll find out where the gap is and why it wasn’t brought to our attention a lot earlier, but we’re glad the investigation is happening,” Ford said on Friday.
Global News sent questions to Ontario Health but did not receive a response ahead of publication.
The potential data breach is the latest issue in a difficult period for Ontario Health atHome, a rebranded and consolidated agency launched by the Ford government.
Supply shortages in the fall left more than 350 people receiving home and palliative care across the province without the medication or equipment they needed.
Delays in delivering supplies came after the government signed new contracts with private vendors for Ontario Health. As a result of the delays, the province had to refund $219,000 to people forced to buy their own medical supplies.
Shamji said the data breach was evidence of an agency which couldn’t function properly.
“Ontario Health atHome has been in disarray for months,” he said. “First with medication shortages and then with supply shortages, then with massive delays in care and now with the protection of personal health information. They’ve failed on all those things.”

Residents of a tiny rural community in eastern Ontario pressed police on Saturday for answers about a disturbing attack on a young girl that investigators believed was caused by an animal — until they arrested a teenager in the case.
Nearly 100 people filled a small community centre in Quadeville, about 170 kilometres west of Ottawa, for a town hall organized by Ontario Provincial Police to address residents’ questions and concerns about their investigation.
Some have asked why the OPP alerted the community about a suspected animal attack on the eight-year-old girl before announcing two weeks later that a 17-year-old boy had been charged with sexual assault and attempted murder.
Police have said that they never ruled out other possibilities, and that their initial theory was supported by medical and pathology experts.
At Saturday evening’s town hall, police did not divulge any new information about the case that is now before the courts, but sought to assure residents they did everything they could to keep them informed throughout the investigation.
The community centre was packed, with no empty seats to be found. As people filed in, the temperature in the room started to increase on a sweltering evening, especially after someone shut off the portable air conditioning unit that was making noise.
“It’s a very traumatic time for this community because everyone knows everyone involved,” OPP Supt. Derek Needham said at the meeting punctuated by some tense moments.
When police opened the floor for questions, a man who identified himself as a relative of the victim asked why it took a long time for police to respond when the girl was initially reported missing on June 23, after she was last seen at a local store.

Police replied that it took time to bring officers to the scene to search the area.
“I could’ve done my own investigation,” said the man, adding that he lives three hours away.

The OPP have said that they began their search for the missing child around 9 p.m. on June 23, and found her with life-threatening injuries not long after midnight.
Police asked people to keep their small children indoors amid fears of an animal attack but as their investigation continued, they discovered that there were no traces of animal DNA from the victim’s wounds. Police have not said what kind of evidence led them to arrest the teenage suspect, who cannot be named under the Youth Criminal Justice Act.
Town hall attendee Sandy Musclow asked police how members of the community should interact with the families of the young girl and the suspect.
“A whole lot of healing needs to take place,” Needham said, adding that the best thing for families to do is reach out and have open communication.
After the town hall ended, Musclow said “it’s been a bit difficult to figure out” how to support both families.
“I’ve grown up with them and we really want to make sure that we feel like everyone can feel the pain and move forward together as a community,” she said.

Musclow said that although residents didn’t get much information about the police investigation at the town hall, she was glad to see the community come together. She also pointed to various fundraising efforts for the girl, who remains in hospital, and her family.
“I just feel that the police did a really good job at giving us some solace that they did the right thing for us and they did everything as timely as they could and they were really looking into everyone’s interest,” Musclow said.
OPP spokesperson Bill Dickson told reporters on Saturday that police were compelled to warn the public about a possible animal attack in the early stages of the investigation, even if they weren’t sure that was the case.
“We couldn’t undersell it because if we didn’t say something and warn people and it was an animal and another child was attacked, that would be horrible,” he said.
Dickson said one of the local churches is bringing in counsellors to work with the community and counselling services from the OPP will also be available.

A new poll by Leger has found that Quebec residents are the happiest in Canada.
The web survey of nearly 40,000 Canadians found that Quebecers rated their happiness at an average of 72.4 out of 100, which is well above the national average.
New Brunswick followed Quebec with an average of 70.2, while Manitoba and Prince Edward Island finished at the bottom of the list.
Mississauga, Ont. had the highest happiness rating of the 10 largest cities, while Toronto was lowest.
Montreal finished second in the category.
The survey found that 49 per cent of respondents said their happiness level was unchanged over the past year, while 23 per said they were happier and 28 per cent said they were less happy.
“These results reveal a population that is both resilient and tested, affected by everyday uncertainty and challenges,” Leger’s executive summary read. “Happiness, while holding its ground overall, shows signs of fragility.”

The survey found that people in the 18-to-24 and 24-to-34-year-old categories were more likely to report improved feelings of well-being, even if their overall happiness score remained below the national average.
In contrast, people in the 35-to-44 and 45-to-54 age brackets were more likely to report their happiness had deteriorated.
“There is a sense of well-being emerging among younger age groups,” the summary read. “However, this also highlights the importance of supporting adults in mid-life, who are more vulnerable to the pressures of working life.”
Quebec, New Brunswick and Newfoundland and Labrador were the three provinces with happiness levels above the national average of 68.7. They were followed, in descending order, by Saskatchewan, Nova Scotia, Alberta, British Columbia, Ontario, Manitoba and P.E.I. The territories were not included in the survey.
In the survey of the 10 largest cities, Mississauga and Montreal finished ahead of Hamilton, Calgary, Brampton, Ottawa, Edmonton, Vancouver, Winnipeg and Toronto, in that order.
Women reported slightly higher happiness levels than men, at 69.4 versus 68.0.
Leger says the overall results confirm “a level of happiness that is relatively high but stagnant or even slightly down compared to the pre-pandemic period.”
To get the results, Leger surveyed 39,841 Canadians aged 18 and up between March 31 and April 13.
Online surveys cannot be assigned a margin of error because they do not randomly sample the population.

Ontario Provincial Police are set to host a town hall in Quadeville, Ont., this evening to answer questions from residents about an attack on an eight-year-old child that was initially linked to an animal.
Police have arrested a 17-year-old boy in the case and he faces charges of attempted murder and sexual assault with a weapon.
Members of the small community 170 kilometres west of Ottawa say they were in shock after hearing about the arrest and hope to get clarity at today’s event in the town’s community centre.
Local resident Christine Hudder says she wants to know how police came up with the animal attack theory and why families were told for days to keep their children indoors.
