This program aims to create favourable conditions for investment projects on land whose economic, residential and institutional development potential is hampered by soil contamination. The contaminated lots must be located in Montréal.

For all projects

• Comply with all applicable Québec laws and regulations, including the Environment Quality Act, the Act Respecting the Preservation of Agricultural Land and Agricultural Activities, the Protection Policy for Lakeshores, Riverbanks, Littoral Zones and Floodplains and Québec’s Action Guide concerning soil protection and contaminated land rehabilitation.
• Involve the complete rehabilitation of the contaminated lot.
• Involve the use of a tracing system that is approved by the province’s Ministère de l’Environnement et de la Lutte contre les changements climatiques (MELCC).
• Promote the use of in situ treatment.
• Promote the treatment of excavated soil for recovery purposes if in situ treatment is not possible.

Private projects

• Build a structure on land used for parking or when the building erected on the land was demolished before April 1, 2019.
• Any structure with a residential component and for which a construction permit application was submitted before April 1, 2021, must:
  • Be eligible for a subsidy under the By-law concerning subsidies for the development non-profit cooperative housing (02-102), or​​​​
  • Be covered under the city’s Strategy for the inclusion of affordable housing in new residential projects, or

Municipal projects

The application will be deemed ineligible if:

• It involves a contaminated lot where landfill, storage, collection, sorting, conditioning, transfer and treatment operations were carried out on or after April 24, 1997, including mine tailings sites, pulp and paper water disposal sites, dry material disposal sites, landfills, storage centres, and soil, water waste and hazardous materials treatment centres.
• Work on the site began prior to the date on which the subsidy application was declared eligible.

Financial assistance is the same for all types of projects. It is provided in the form of subsidies equal to 15 to 75 per cent of eligible project expenses, depending on the nature of the project and the type of decontamination technology used.

For example:

• Off-site transport and disposal: 15 to 30 per cent
• On-site treatment and transport or treatment at an authorized site: 70 per cent
• in situ treatment: 90 per cent

In all cases, the sum of the municipal subsidy and the federal and provincial assistance must not exceed 75 per cent of eligible expenses.

The maximum subsidy for former waste disposal sites is $500,000.

This program has been integrated into one of the 2016-2020 Sustainable Montréal Plan’s action items: Implementing a soil decontamination program. Land decontamination reduces soil pollution and purifies runoff water in addition to reducing heat islands, in some cases.

You have until December 31, 2023 to submit an application.

Rehabilitation work must be completed within a maximum of 60 months of the eligibility start date. An additional 24 months may be granted for in situ decontamination, with valid supporting documents.
