Water Weed Control Services

Water Weed Control

Our environmentally safe Aquatic Weed Control Service benefits our clients by removing invasive water weeds in your recreational waterfront property or marina, and our Pond Vegetation Control service removes phragmites and other invasive plants around your ponds and other water bodies.   If you have troublesome weeds that are keeping you from enjoying your waterfront, we can help.   We are licensed to remove weeds in water in all of Ontario.  Our fees are very reasonable and bulk pricing is possible.  In compliance with the Ministry of Environment, Parks and Conservation and Parks (MECP) we must apply for a permit from to service your property, so it is imperative that give us your contact information early in the year (Jan-April) as this process takes some time.  Don’t wait until the summer, as it will be too late for us to get your permit approved.  We encourage you to review the information provided on our website, and if you have any further questions feel free to fill in our email formemail us directly or call us.    

Aquatic Weed Control

Weeds In Water Bodies


We begin treating weeds in water bodies in June and July, but the permit process starts early in the first quarter of the year. We are licenced from the Ministry of Environment, Conservation and Parks (MECP) to remove water weeds such as Eurasion water milfoil and coontail. We are licensed to control these weeds in ponds, lakes, rivers, lakes and marinas.

Pond Vegetation Control

Phragmites And Other Invasives
Around Water Bodies

Phragmites E. Common Reed is a non-native, invasive Eurasian plant spreading quickly in North America. The huge towering reed can take over ponds and surround water bodies. Luckily, this type of pond vegetation can be treated throughout the year. We have permits from the Ministry of Natural Resources and Forestry (MNFR) to control Phragmites E. Common Reed in dry ponds, dugouts or roadsides.

Important Notes:

  • Areas allowed to be treated are at the discretion of the Ministry of the Environment, Conservation and Parks (MECP), not Peerless Aquacare.   
  • We must follow the rules laid out by the MECP to maintain our weed removal licences.
  • Similarly, the provincial Ministry of Fisheries and Oceans Canada (DFO) dictates the timing of the application of the herbicide.
  • Reward® Aquatic Herbicide is applied out of the boat.  The chemical is premixed with a sample of lake water then injected into the lake via our proprietary pump system.  We make several passes over the set area so the allowed amount of product gets into the lake.
  • The full surface area to be treated is measured by laser.
  • The product is heavier than water so it sinks to the bottom where plants absorb it.
  • It can take up to 12 days for the plant numbers to decrease.   A number of factors can affect this, such as water temperature, sunlight, wave action, etc.
  • The substance then degrades at the bottom of the lake.
  • The MECP does not allow any re-sprays.  Treatment is allowed only once per year and cannot be administered twice in the same year.
  • Peerless Aquacare services are non-refundable.   Our charges include work done to secure permits as well as the spray job itself.
  • After treatment, in some cases, the MECP also requires submission of a report.
