Canadians deserve
to know.
I'm going to tell you.

"Does asbestos cause cancer in the United States — but not in Canada?"

Asbestos fibres have been found in Winnipeg tap water. Canada has no legal limit. Health Canada proposes to keep it that way. One Human Rights lawyer decided that wasn't good enough for Winnipeg — or for any Canadian family.

Asbestos Free Water was founded by Rana Bokhari, a Human Rights lawyer based in Winnipeg, Manitoba. In 2022, Rana wrote to the Federal Minister of Infrastructure — copied to the Prime Minister of Canada — drawing attention to 721 kilometres of asbestos cement pipes beneath Winnipeg's streets and demanding action.

When W5 independently tested Winnipeg's tap water and found approximately 60,000 asbestos fibres per litre, Rana founded Asbestos Free Water. She mapped every asbestos cement pipe beneath the city. She built a free public resource. She responded to Health Canada's consultation on behalf of Winnipeg and all Canadians. She submitted simultaneously to the United Nations Special Rapporteur on Safe Drinking Water.

This is not a fringe issue. Asbestos is a Group 1 carcinogen — the highest classification of the International Agency for Research on Cancer. It is banned in Canada. Yet the pipes carrying it into Canadian homes are still there, still crumbling, and the water they contaminate remains unregulated.

Canadians deserve to know. We are going to tell them — until somebody does something about it.

The record.
Everything we have done.

Every letter. Every submission. Every institution that now has this on their record.

What was ignored.

W5 · CTV Investigation · 2024

Something in the Water

Canada's longest-running investigative newsmagazine commissioned independent testing of tap water across six Winnipeg neighbourhoods. Results: approximately 60,000 asbestos fibres per litre in residential samples. Near a Regina pipe break: 370,000 fibres per litre.

1977
A Health & Welfare Canada study confirmed 6.5 million asbestos fibres per litre in Winnipeg's water and confirmed active erosion of asbestos cement pipes. That was nearly 50 years ago. Canada still has no enforceable limit.
Health Canada · March 2026

Draft Guidance on Asbestos in Drinking Water

Health Canada's 64-page guidance document proposes no Maximum Acceptable Concentration for asbestos in drinking water. Winnipeg — where W5 found 60,000 fibres per litre — is mentioned only in passing. Asbestos Free Water responded to the consultation in support of Winnipeg and all Canadians.

National Research Council Canada · 2010

Bacteriological Challenges to Asbestos Cement Pipelines

Federal government scientists confirmed that severely deteriorated asbestos cement pipes release fibres into drinking water and could pose a hazard of malignant tumours of the gastrointestinal tract. The NRC noted significant increases in pipe breaks and failures.

Letter to the Federal Minister of Infrastructure

In July 2022, Rana Bokhari wrote directly to the Federal Minister of Infrastructure, citing the 1977 federal study, 721 kilometres of asbestos cement pipes beneath Winnipeg, and the absence of any regulatory response. The letter was copied to the Prime Minister of Canada.

US EPA · 1991

The Standard Canada Has Yet to Match

The United States EPA set an enforceable limit of 7 Million Fibres per Litre for asbestos in drinking water in 1991 — over 35 years ago. The EPA states that beyond this limit, steps must be taken to prevent serious risks to public health. Canada has not acted.
