Plants – tireless, silent workers 

The Montréal Botanical Garden is proud to present the Pathway to Phytotechnologies, an exciting and ambitious project. Thanks to many years of research and collaboration between scientists at the Botanical Garden and at the Institut de recherche en biologie végétale (IRBV), thousands of live plants will begin working silently to demonstrate their abilities in terms of rehabilitation, decontamination, soundproofing, filtration, stabilization, runoff control and air and water purification.

A $14.5 million fundraising campaign

The city of Montréal will invest one dollar in the Pathway for every dollar raised by the Foundation, to cover the estimated $14.5 million cost. To date the Foundation has raised over $1.1 million, thanks to contributions by RBC and the Québec Mining Association, making it possible to develop the Filtering Marshes station, and donations by the Claudine and Stephen Bronfman Family Foundation and the J. Armand Bombardier Foundation, which will go to promoting the educational aspects of the project. 

  • 2018 - Filtering marshes - $775 k

    Plants at this station will purify the water circulating in the different aquatic plant basins. 

  • 2019 - Living plant wall - $1,26 M

    This vertical ecosystem will clean the air, increase humidity levels, serve as a sound barrier and provide shelter for birds and insects.

  • 2019 - Decontamination  - $3,9 M

    The soil above a former landfill will be used to create a demonstration zone looking at the use of phytoremediation for decontamination.

  • 2020 - Controlling invasive plants (created in combination with the Decontamination station)

    The pond at the Frédéric Back Tree Pavilion is badly affected by invasive plants and will be used to illustrate various rehabilitation techniques.

  • 2021 -  Filtering marshes and green roof - $1,43 M

    At the Youth Gardens, a new building with washrooms and a green roof will be added, and its greywater will be treated by means of filtering marshes.

  • 2021 - Stabilizing pond banks - $3,3 M

    Plants will be used to stabilize the banks and limit the spread of invasive plants in and around the ponds.  

  • 2023 - Cold islands - $3,8 M

    A number of water retention zones will be created in the parking lot, and equipped with a green filtration system for better rainwater management and to reduce the heat-island effect.
