What you’ll find on REMtl?

REMTL.ca is a source of information about the progress of soil remediation on the island of Montreal. Besides mapping of affected land, you will find information on the main pollutants and their potential effects on health.

ReMTL.ca takes no responsibility for such information. If you have comments or questions, contact us here.

Why a site like REMtl.ca?

Like many Canadian cities, Montreal is grappling with significant soil contamination problem, the result of nearly two decades of human and industrial activities. In recent years, very strict laws were passed to force developers to decontaminate the soil prior to complete their project. Using information available in the public space, the website portrays the progress of soil remediation on the island of Montreal, a field at a time.

Pollution that affects human health can be grouped into three categories: air, water and soil. In Montreal, a lot of effort and research has focused on air pollution and noise. The water quality in Montreal is generally considered safe. Little attention was paid to soil decontamination although it must be a long-term goal for sustainable development of a city.

In a tight budgetary situation, is that the soil decontamination is a priority?

Decontamination is an expensive process. Depending on soil and extent of pollution, soil contamination is a relatively minor problem compared to the pollution of air and water. The laws and regulations require developers to reduce health risks by decontaminating the soil to a minimum level of safety. Some contaminants produce harmful fumes while others are dangerous when ingested. Finally, agriculture on contaminated land is dangerous.

Does the citizen (ne) s or groups can participate in REMtl?

We do not plan for now to call on external participation but we are interested in any suggestions.

Who can use REMtl?

We have identified several groups of people who might be interested in this information, and we are also interested in studying any other use:

– Proponents of urban agriculture

– Researchers and academia

– The groups interested in environmental protection

– Ls promoters

– Home buyers

What are the main contaminants in the soil?

  • Heavy metals (lead, cadmium, mercury among others)

  • Persistent organic pollutants (POPs), incuant polycyclic aromatic hydrocarbons (PAHs)
  • Polychlorinated biphenyls (PCO)

What does that mean “A Beach”?

The city of Montreal wrote a summary that explains the levels of decontamination citizens . The 

Ministry of Sustainable Development, Environment and Parks has written a more scientific explanation page .

Do REMtl.ca tabulate all contaminated land in Montreal?

No, REMtl.ca geolocated only the sites that are listed in the website of the Government of Quebec and a sample sites that originate from the website City of Montreal .

This first, the Directory of contaminated land , is created and maintained by the Ministry of Sustainable Development, Environment and Parks, contains general information on land contaminated with industrial and commercial activities, or accidents. It is not a comprehensive inventory; other sources, such as municipalities, may also have other information in this field. The website of the City of Montreal is one example.

The regional directorates of the Ministry are responsible for collecting the information. According to their website, all requests for information on a specific folder in the Montreal region must be addressed directly to the management concerned. For the City of Montreal, here is their page Soil quality and citizens .

What brownfields are not identified?

The contaminated soil management is governed by the Environment Quality Act (see Sections 31.42 to 31.69) which is applied by the Ministry of Sustainable Development, Environment and Parks. In general, only land where the owner files a change of use application is subject to regulation arising from this Act (section 31.53). Notwithstanding, the ministry has the right to act as the contamination of land is dangerous, that is to say: ‘likely to affect the life, health, safety, welfare or the comfort of human beings, other living species or the environment in general ‘(Article 31.43). In other words, there are other contaminated sites in Montreal, in addition to those that are cataloged in the Directory of contaminated land.
