• City’s Aerial Spray Program – week of May 21st

    City’s Aerial Spray Program Begins Next Week
    May 17, 2018

    With the warmer weather conditions, the City of Mississauga has tentatively scheduled its aerial spray program to begin next week to manage cankerworm and gypsy moth caterpillar populations. Private and public lands in specific areas of Wards 1, 2, 6, 7, 8 and 11 will be sprayed.

    The City has drafted a detailed FAQ to address specific questions regarding the spray. The City will continue to share information about the spray at mississauga.ca/2018spray and via social media. Residents are also encouraged to sign up for aerial spray news alerts.

    “The spray is contingent on leaves being at least 30 per cent expanded and caterpillar hatch out as close to 100 per cent as possible,” said Jamie Ferguson, Aerial Spray Project Lead for the City of Mississauga. “When those conditions are met, we then need to monitor weather for the right temperature, humidity, low wind and no precipitation in the immediate forecast.”

    As a result, specific spray dates are chosen 48 hours in advance and they can be cancelled up to 12 hours in advance if weather conditions change. The City will issue notice to the public 48 hours before each treatment on the aerial spray website and provide up-to-date information through 3-1-1 and through the City’s Twitter channels (@CityMississauga and @MississaugaPF) and on Facebook (facebook.com/citymississauga).

    Spray Method
    The City has contracted Zimmer Air Services to implement the spray. Two applications will occur over a three-day period between the hours of 5 to 7:30 a.m. Two helicopters with a spray system will fly about 15 to 30 metres above the treetops. Spraying is weather dependent and will only be done under the right conditions.

    Closures and Traffic Disruptions
    The City will be implementing a traffic plan that requires temporary roads, parks and trails closures, including Rattray Marsh. The closures are necessary to meet approval requirements from Transport Canada. Road closures are expected to last less than 30 minutes, between 5 to 7:30 a.m. All emergency services will have full access to all properties within the spray zones.

    Preparing for the Aerial Spray
    he City is committed to ensuring all possible steps are taken to keep Mississauga healthy and habitable for all residents. The safety and health of residents and the protection of the environment are top priorities. The public may hear helicopter noises during the early morning. All necessary safety precautions are taken to ensure minimal risk to the public, staff and the applicators.

    Residents are unlikely to experience any health effects and no special precautions are necessary or required. Individuals who would like to avoid exposure during a spray program may wish to consider the following measures:

    • Remain indoors during the spray and up to 30 minutes thereafter
    • Close doors and windows when the spraying is taking place
    • Bring in laundry, toys and pets indoors before spraying begins
    • Practice good personal and food hygiene (e.g. hand washing after outdoor activities, especially after gardening; leave outdoor shoes at the door; washing all fruits and vegetables before eating or cooking)
    • Cover lawn furniture, automobiles, outdoor tables, pools, BBQs, play equipment and sandboxes and/or rinse them¬ with water after spraying is finished
    • Leave heating units/air conditioners on, with vents set to the closed position, or selecting the recirculate function
    • Contact Peel Public Health or your family physician if you are concerned that a personal medical condition may be aggravated by the spraying

    About the Spray
    The City of Mississauga will be using a Bacillus thuringiensis subspecies kurstaki (Btk), registered under the trade name of Foray® 48B. Btk is a naturally occurring bacterium found in soil and is not a chemical. It has been successfully used by the City of Mississauga in 2006 and 2007 to control gypsy moth populations.

    Once applied, Btk biodegrades quickly, in approximately one to four days, through exposure to sunlight and other microorganisms. There are no groundwater contamination concerns as Btk does not travel through the soil beyond 25 cm. Btk is specific only to caterpillars and does not have impacts to mammals, birds, fish, or other insects, including honey bees.

    Residents with questions or concerns related to the health impacts of aerial spraying with Btk can call the Region of Peel Public Health at 905-799-7700 or speak to their family physician.

    For up-to-date information about the aerial spray details such as road closures, spray dates, times and locations, call 3-1-1 or visit mississauga.ca/2018spray.

  • Open House for 2018 Aerial Spray Program to Combat Cankerworms and Gypsy Moths – April 10

    This spring, the City of Mississauga is conducting an aerial spray. The spray will lower fall cankerworm and gypsy moth caterpillar populations and prevent tree loss. To prepare for the spray, the City is hosting five information open house events for those who live or work in the designated spray areas.

    City staff will share details about the spray, explain how to control fall cankerworm and gypsy moth caterpillars on private property and provide an overview about the long-term health of Mississauga’s tree canopy.

  • Cankerworm – Tree Banding Update

    Forestry staff are recommending that now is an appropriate time to remove the sticky bands from the trees.  The City just finished removing the bands on city-owned trees in early January.  This is because most, if not all of the female cankerworm moths have finished emerging from the ground. This will give the trees some time to dry out (breathe) before another band is placed in April to catch the caterpillars.


    Below is  information on gypsy moth and cankerworm lifecycles and approximate timing of control measures to help out. 


    There will be open houses this Spring with additional updates and aerial spraying information. I will update you with these dates, when available.



  • Region of Peel Geotechnical Investigation on Lakeshore Road West: Lane closures/restrictions

    The Region is currently undertaking a Class Environmental Assessment for the decommissioning of the Front Street Sewage Pumping Station and re-routing the flows to the west by constructing a trunk (large diameter) sanitary sewer along Lakeshore Road West as shown in the attached sketch.


    This project has been selected to receive Infrastructure Canada funding under the Clean Water and Wastewater Fund. The Region has decided to advance the geotechnical work for detailed design of the proposed trunk sewer to reach the project milestones set by the funding program.


    A geotechnical investigation has been initiated which includes drilling boreholes and installing monitoring wells along the entire alignment as part of the detailed design for the trunk sanitary sewer. The sewer, when constructed, will be in a tunnel underneath the municipal right-of-way, with minimal impact on traffic.


    The geotechnical investigation for the Lakeshore Trunk Sewer will result in lane closures on Lakeshore Road West as per the details below:


    Name of the Road to be closed: Sections 100-200m in length on Lakeshore Road West between Front Street and Owenwood Drive.


    Duration (Date/Time) for the closure: January 15 to May 31, 2018 between 9 a.m. and 4 p.m.


    Apart from Lakeshore Road West, boreholes will also be drilled on the following side streets resulting in a lane closure lasting only for one day for each street between 7 a.m. and 7 p.m.:

    • John Street South
    • Peter Street South
    • Mississauga Road South
    • Benson Avenue
    • Pine Avenue North
    • Maple Avenue North
    • Maple Avenue South
    • Broadview Avenue
    • Shawnmarr Road
    • Crozier Court
    • Ibar Way
