Key points at a glance Key points at a glance. Original editorial diagram. Some boat policies won't pay for freezing damage during lay-up unless you can show a receipt for professional winterization.
Quick answer: Before winter, pull out your policy and ask your broker six things: your lay-up dates, how freezing damage is treated, what winterization records are required, whether your storage plan matches, whether the boat is described correctly, and what to do if you find damage. Get the answers in writing. Our winterization work order lists what was done.
Key points at a glance. Original editorial diagram.
Some boat policies won't pay for freezing damage during lay-up unless you can show a receipt for professional winterization. That one line is a good reason to take your policy out of the drawer before the boat goes away for the winter.
This is the winter companion to our Ontario boat insurance guide, which covers how to buy and compare coverage. Here we're past that. You have a policy, the season is ending, and you want to be sure the winter plan fits it.
We're a marina, not a broker, so we can't tell you what your policy covers. What we can do is hand you the questions and tell you what we see on the service side. Start with your declarations, policy wording and endorsements. Then describe your winter plan to your broker and ask for answers tied to those documents, not to a friend's policy or last year's renewal.
1. What Dates and Restrictions Apply?
Ask whether your policy has a lay-up period or other seasonal restrictions. Write down the actual start and end dates and what the policy allows during that window.
Here's a real example of how specific these get. In May 2024, Aviva explained that under its watercraft policy, boats had to be out of the water and winterized from November 30 to April 1, with an exception for the ice-free Pacific coast and permission, endorsed on the policy, needed for anything else. That's one insurer's terms from one year, but it shows the kind of dates to look for. It also lands almost on top of our own closed season, December 1 to April 1.
On Rice Lake, this matters most in the shoulder weeks. A last walleye trip in late fall, or an early launch in April, can sit right at the edge of a lay-up date. Ask before you go, not after. If you need permission or an endorsement, get it through your broker before you change the plan.
2. How Does the Policy Treat Freezing Damage?
"Boat insurance" doesn't mean "all winter damage is covered." Ask your broker to point to the freezing and ice exclusions, any exceptions, and the conditions attached to them.
Pacific Marine Underwriting's public February 2022 Yacht wording for Ontario, Manitoba and Saskatchewan is a good illustration. It excludes ice and freezing damage while the boat is afloat. It also excludes freezing while the boat is laid up, unless you provide a receipt proving the winterization was paid for and performed by a licensed marine mechanic, a boat repair facility or a reputable marina. Its opening agreement names the declarations and endorsements as part of the contract, too.
Your wording may say something different. The question that gets you a useful answer is: "Which clause applies to my winter arrangement, and what do I have to do to comply?"
3. What Work and Records Are Required?
Ask who's allowed to do the winterization under your terms, and what evidence the insurer expects. If the answer includes professional work or a receipt, find out what the record needs to show.
Then compare that against the service you're actually asking for. An engine invoice shouldn't leave you wondering whether the livewell, the freshwater system or anything else that holds water was included. Ask your service provider to describe the agreed work, and keep the completed record.
Keep photos, invoices and the boat's identifying details together in one file. Paperwork won't guarantee a claim gets paid, but an empty file makes every conversation with an adjuster harder.
4. Does the Storage Arrangement Match?
Tell your broker where and how the boat will be stored: ashore or afloat, at home or at a facility, on a trailer or another support, and under which cover.
Approving one arrangement doesn't approve all of them. Ask what changes need notice, and whether your broker needs the storage location on record. If you might move the boat mid-winter, from the driveway to a marina or the other way around, say so now.
Be specific enough that your broker is answering the question you actually meant.
5. Are the Boat and Equipment Correctly Described?
Read the declarations against the boat you own today. A repower, a different trailer or added electronics is a reason to ask whether the records and insured values need updating.
Check the hull and engine identifiers, not just a familiar model name. Ask how separate equipment is treated and which limits or deductibles apply. Chubb's Canadian overview walks through the common distinctions, such as agreed value against actual cash value, and it's clear that coverage is subject to the policy as actually issued. (Understanding boat insurance, Chubb Canada.)
The goal isn't to push a number up by guessing. It's to make sure you and the insurer are describing the same boat. If you've repowered, the pleasure craft licence update is a good time to check the rest of the paperwork matches too.
6. What Should I Do If I Discover Damage?
Save your broker's contact details now and ask about reporting, documentation and preventing further damage. Find out what has to happen before repairs begin.
Keep the written answer with your policy file. If you find a problem, call your broker promptly instead of trying to decide from a blog post whether it qualifies.
Finish the conversation with a simple request: "Please confirm the relevant clauses and any changes we agreed to." A good winter file holds the current contract, clear answers and records of the work actually done.
What We See at HBW
When an insurer asks for proof a boat was winterized, the record that answers it is the invoice. Our winterization work order and invoice is that record. If your policy asks for evidence, ask us to list the systems we did on it: the engine, plus any livewell, freshwater, washdown or other systems you had us handle. We winterize and store all brands, so the same applies whether your motor is a Mercury or not.
A few HBW details your broker may ask about:
- Storage is outdoors, shrink-wrapped.
- Winterization is a separate service from storage, so make sure both are on your request.
- Batteries stay in the boat, disconnected. We check and charge them as required in the fall and again in spring.
- Storage customers get a free spring check.
If you want any of that written on your work order, say so in the notes when you complete your request at hbwservice.ca.
Timing: mid-November is last call, and we close December 1 and reopen April 1, so have the insurance conversation before the boat comes in, not the week after. For what the work involves and costs, see our winterization cost guide. For where outdoor wrap fits against indoor storage, read the storage comparison.
