The cost for decontaminating a non-motorized watercraft is $5.
Unless you are staying on the territory of Messines for the entire summer, you must pay the visitor rate directly at the decontamination station ($25 per decontamination session). If your place of stay is on the shore of the lake where you plan to navigate, your decontamination certificate remains valid as long as you do not remove your boat from the water. If during your stay you decide to visit other lakes, including those in Messines, you will need to use the decontamination station again and pay the $25 fee to obtain a new decontamination certificate.
No. To qualify for an access card at the resident annual rate, you must prove ownership of the watercraft. Otherwise, the person placing their watercraft on your property must obtain their own card at the non-resident annual rate.
You must provide proof that you live at that address (e.g., an electricity bill in your name, your driver’s licence showing the address, etc.) and register as a tenant rather than a property owner. You will then be eligible for an access card at an initial cost of $15. There is no annual renewal fee, unless a replacement is needed due to loss, damage or theft of the card.
There is no specific rate for the rental or loan of a dock space. If you are a resident of Messines, whether you are an owner or a tenant, the annual resident rate applies.
Residents of Messines (property owners, their spouses, children and stepchildren, or resident tenants) can purchase an access card for a one-time cost of $15. This card gives you unlimited decontaminations for the season. There’s no annual renewal fee. If the card is lost, damaged or stolen, a $15 replacement fee applies.
When registering their watercraft, owners must indicate the mooring location.
There is no specific rate for dock rentals or dock loans. The rate is based on your residency status, not on dock access.
Yes, a pass is available for non-residents. The annual non-resident rate is $150, which gives you unlimited access to the decontamination station for the season.
If you’re a non-resident but renting a campsite or cottage for the entire summer, you may be eligible for the seasonal rate of $80. To qualify as a seasonal resident, you must submit the appropriate form, completed and signed by the authorized person listed on it, confirming your seasonal rental of a residence, cottage or campsite.
A resident is anyone who lives permanently in Messines (either as an owner or tenant) or who owns a secondary residence in the municipality. Anyone who owns property (land) in Messines is also considered a resident. This definition also includes the resident’s spouse, children and stepchildren.
Boats stored on shoreline property adjacent to a body of water that have not been used on another body of water do not have to be decontaminated upon initial launch, and this remains the case as long as your boat does not leave the body of water bordering your property.
Once it leaves the lake, however, it must be decontaminated upon its return.
No. To ensure your watercraft is properly decontaminated, you must use a pressure washer with a force of 2,600 psi. Anything less may not remove all the organisms. Temperature is also key — the water must be kept at a constant 60°C.
You must decontaminate your watercraft before every launch. As soon as your boat leaves a lake, it must be decontaminated before being launched again—no matter which body of water, as long as it’s within the territory of the Municipality of Messines.
Yes, decontamination of watercraft is mandatory.
The Municipality of Messines has passed a regulation requiring watercraft to be decontaminated before launching on any bodies of water within its territory.
Decontamination and inspection of watercraft are effective measures to prevent the spread of invasive exotic species, and all boaters can do their part to keep our waterways healthy for future generations.
Your cooperation is essential for the protection and the preservation of our lakes.
First, the certificate confirms that you have decontaminated your watercraft. Additionally, the certificate includes a QR code that allows access to the lake by opening the barrier for both launching and exiting. Your decontamination certificate remains active as long as you stay on the lake.
