Canada, From Toronto | Answers, Not Abandonment — November 15, 2026 (Morning Edition)

Good morning from Toronto — clear skies here, 3°C and a wind that still has opinions, but the coffee is warm and the Sunday paper is doing something rare: telling a small-province story like it matters. Because it does.

Why I picked this today

Pillar 4 — Systems That Shape Life — plus Atlantic / New Brunswick. Canada's federal public-health agency has finished an independent review of more than 200 "mystery brain disease" patients in New Brunswick and found no single cause. The story is not the mystery; it is what happens to people when a system finally, imperfectly, looks back at them and says: we owe you a proper reassessment. Atlantic Canada has not anchored this blog all week. Today it does.

The Story

The review, in one sentence

The Public Health Agency of Canada says it found no evidence of a single, unusual neurological illness or a common cause in its review of more than 200 so-called mystery brain disease cases in New Brunswick, CBC News reported on Nov 13 — but it leaves the door open to a common illness among a subgroup of patients, and it recommends reassessing patients so they can finally get diagnoses, care, and prognosis information.

The patients who named the alarm

Moncton neurologist Dr. Alier Marrero is one of the specialists who first sounded the alarm about a possible mystery illness about six years ago, CBC reported. In 2023 he raised concerns regarding elevated levels of the herbicides glyphosate and glufosinate, and several heavy metals, such as aluminum, arsenic, lead and mercury, in some patients, as well as rare antibodies. He has previously said about 500 patients across seven provinces are suffering unexplained neurological symptoms — although the report indicates some patients have since been diagnosed.

Marrero is still working with Vitalité Health Network and continues to provide follow-up care to his patients, the health network says.

What the federal review actually reviewed

PHAC launched its review and assessment in the spring at the request of the New Brunswick government, after patient representatives and Marrero called for an independent scientific review of all the raw clinical data. Its review assessed data for 210 of the 222 patients who did not opt out of having their data shared, covering Jan. 1, 2020, to Feb. 28, 2025, CBC reported. It assessed provincial data on Creutzfeldt-Jakob disease (a rare neurological disease) and hospital stays for neurological illnesses. It reviewed death certificates for 24 of the patients and found several different and known neurological conditions.

The agency also met with patients, their caregivers and Marrero — identified only as the "reporting neurologist" — and consulted federal experts in public health, epidemiology and statistics, clinical medicine, and behavioural science.

The hard limit: data with holes where diagnoses should be

PHAC cites the "overarching limitations" of the data, including a lack of diagnosis for most of the patients, whose symptoms range from painful muscle spasms and hallucinations, to memory loss and behavioural changes, CBC reported.

"Often, patient information did not have a medical summary that described the patient illness," a plain-language summary of PHAC's 76-page report says. "There was a lot of information about tests, but the meaning of the test results was not explained for each patient."

"As a result, we cannot tell whether a smaller group of patients might have a common illness or not."

PHAC notes all 222 patients are a subset reported by a single neurologist, and how they were selected and how representative they are is unclear. The data "does not have enough granularity" to assess geographic clustering because New Brunswick removed identifying patient information such as addresses. Among nine cases reported as being from out of province, six had a known connection to New Brunswick — an active or expired Medicare card or a New Brunswick phone number — and the report says there is no evidence of a multi-jurisdictional concern.

The provincial layer beneath the federal one

A provincial investigation earlier this year into 222 of the patients for whom Marrero had completed enhanced surveillance forms found no evidence of widespread environmental exposure contributing to illness and no new brain diseases, CBC reported. It did not identify what is making people sick, but the findings — along with a 2022 report on an initial group of 48 patients primarily clustered on the Acadian Peninsula and Moncton area, and a scientific study published in May 2025 in the Journal of the American Medical Association — suggest patients are likely suffering from an illness that can be diagnosed, Dr. Yves Léger, the chief medical officer of health, has said.

"We're no further ahead"

"We're no further ahead," said Sarah Nesbitt, who is one of the patients and serves as a co-liaison between them and the provincial government. "The patients still don't have treatments or diagnoses, and we still don't know what is making New Brunswickers sick."

Nesbitt, 43, of Canaan Station just north of Moncton, says PHAC focused on finding a common cause, but "we didn't necessarily say that it was one common cause, you know, like one herbicide or one heavy metal." Patients just wanted to know what was making them sick, she said, noting some are dying.

"I think at this point, everybody's lost faith in the public health agencies to actually find out and look deeper and OK, if you don't have the available data, ask for it. Get it. You know?"

Still, Nesbitt is encouraged that patients aren't being abandoned and will be reassessed. "For me, the main goal is getting patients help, not proving Marrero right, not proving the government right, it's getting help for patients." She considers herself one of the lucky ones and now has a tremor specialist and a spine specialist, and hopes other patients can get treatment that puts them "on the right path to healing."

The promise inside the recommendations

PHAC recommends New Brunswick continue to communicate with patients, caregivers and the reporting neurologist; support patients to get clinical assessments and care that may help with a clear diagnosis and related treatment; gather and look at new medical information; and work with health partners to ensure future reports clearly explain what the health issue is and why it is being reported.

Léger said the government has accepted PHAC's recommendations, and thanked the federal agency for its "significant work" on the file. "Our primary concern has been, and remains, the well-being of the affected patients. We will continue to work closely with the regional health authorities to ensure patients have access to the care and support they need." On Oct. 29, the provincial government posted that it is working with regional health authorities to provide reassessments to patients who are interested.

Why It Matters

For a Torontonian, this is a story about what a health system owes people when it cannot give them a clean answer. The review's most important sentence may be its most cautious: PHAC found no unusual pattern of neurological disease in New Brunswick either, "Yet, important uncertainties remain." That honesty matters more than a headline. The province now owes patients something concrete — reassessments that turn lab results into named diagnoses, specialist referrals like the ones Nesbitt found, and plain-language explanations of what tests actually mean. If that happens, families who have spent years in an evidence vacuum get care. If it becomes a press release and a shrug, trust in public-health institutions erodes further — and that loss would be felt far beyond the Acadian Peninsula.

One Thing To Know

If you or someone you love is living with unexplained neurological symptoms, the practical takeaway from this review is to ask for a fresh clinical reassessment and a plain-language explanation of your own test results — not a headline about "mystery illness." PHAC's own recommendation is that reassessments should reduce patient distress and deliver diagnoses, care and prognosis information. This is general information, not medical advice, and it does not mean every case shares one cause or that environmental testing is settled science — the review explicitly left uncertainties open. Talk to your own clinician for personal care.
