Here are useful resources on environmental issues if you live in the borough of Saint-Laurent.

You have probably heard about the emerald ash borer, the insect pest from Asia that is infesting ash trees across North America. The disappearance of thousands of ash trees not only impacts the landscape but also poses a risk to public health in cities exposed to heat islands.

The emerald ash borer is now unfortunately found throughout Montréal, and the City has undertaken a series of measures to contain the infestation, notably by treating trees with bio-pesticides. Saint-Laurent is a pioneer in the field as it has treated all ash trees in the public domain in the borough.

Residents are responsible for the care of ash trees on private property. It is important to take quick and efficient action. Contact us for information on caring for your ash tree.

Organic matter accounts for 35 to 40% of the waste in our garbage bins. This includes kitchen scraps, green waste and other common biodegradable household waste. Composting makes it possible to recover this waste.

In 2016, Saint-Laurent implemented the collection of organic waste for residential buildings of 8 units or less. Residences each received a brown bin and a small countertop bin. These containers are used to collect all organic matter, green waste and food residues so that they are treated properly.

The following types of organic waste are accepted:

  • Food residues
  • Soiled paper and cardboard
  • Green waste
  • Other types of waste (toothpicks, animal food and fur, feathers, hair, tissues, etc.)

For more information, see organic waste collection in Saint-Laurent.

Household composting is another way to recover organic matter. Thanks to a borough subsidy, backyard composters are available for $20. We also provide assistance to help you get started.

Every year, the borough of Saint-Laurent, in partnership with the Éco-quartier Saint-Laurent, gives out free compost. Collected organic matter is transformed into natural fertilizer for flower and vegetable gardens as well as cultivated and cultivable areas.

Bring your own container and a proof of residency to the Municipal Workshops located at 13001 Cavendish Blvd in Saint-Laurent to get your free compost. To find out when this event is held, visit the borough’s Facebook page, Twitter account or website.

There is now an ecocentre located at 3535 Sartelon St. in Saint-Laurent where various types of waste can be dropped off for proper recycling.

One of the roles of the Éco-quartier Saint-Laurent’s green patrol is to educate citizens about the ragweed plant whose pollen is known to cause hay fever. In order to eradicate this annual plant and lessen allergic reactions, it is recommended to uproot it as soon as it manifests itself on your property.

How to identify ragweed

Collecting rainwater is a simple technique that allows you to:

  • Reduce the negative effects of rainwater runoff and sewage overflow during storms (which can result in sewer backups and surplus discharge in natural habitats)
  • Save water (collected water can be used for gardening)
  • Protect your house foundations from water leakage from roof

To encourage citizens to collect rainwater, the borough of Saint-Laurent sells rain barrels at the reduced cost of $20. Contact the Éco-quartier Saint-Laurent for more information.

Note: In 2013, the City of Montréal adopted a bylaw on water use stating that watering is only permitted at certain periods. Watering paved surfaces such as asphalt (still unfortunately too common) is strictly forbidden.

Recycling consists in recovering certain types of residual materials in order to transform them industrially and give them a second life. All unsorted residual materials are collected in green bins.

Accepted materials:

  • Paper and cardboard (newspaper, boxes, magazines)
  • Plastic other than number 6 (bags, containers, bottles)
  • Metal (cans, aluminum)
  • Glass (bottles, containers)

The following items are not accepted:

  • Number 6 plastics

Hazardous household waste (HHW) includes various common household products such as paints, used oils, solvents, batteries, pesticides, and cleaning products.

HHW, just like electronic devices (televisions, cell phones, computers, printers, etc.), must be recycled and treated separately and ecologically. To do so, simply drop off HHW and electronics at your local ecocentre, which recovers them free of charge.

Keep in mind:

  • Since the implementation of environmental handling fees (EHF) in 2013, electronics retailers are obligated to recover electronic devices (similar to the types sold) at the end of their service life. See the list of authorized drop-off points.
  • In Saint-Laurent, there are drop-off points for CDs and DVDs (including cases), cell phones and batteries in all public buildings.
  • You can deposit the following items in our offices for recycling: batteries, CDs, DVDs (including cases), cell phones, ink cartridges and compact fluorescent lamps.
