General information only. This guide explains, in general terms, how Canadian cottage and seasonal-home policies treat an empty property over the off-season. It is not insurance advice, it does not recommend any insurer or product, and it is not written by a broker or agent. Every policy writes its own conditions — confirm anything that matters with your own insurer or broker, and treat your policy documents as the final word.

Your policy is in force all winter. Is your coverage?

That is the question a cottage policy answers in two different places. The declarations page says the policy runs for twelve months. The vacancy clause — a set of conditions buried in the wordings, written for exactly the months nobody is there — decides whether a winter loss is paid under the coverage the owner thinks they bought. Standard homeowners policies are built for primary, year-round residences, and the Insurance Bureau of Canada notes that seasonal properties can present higher risks than a primary home. The clause is where that higher risk gets priced into conditions instead of premiums.

The bottom line, before any detail: for a seasonal property, meeting a handful of written conditions during the empty months is not housekeeping. It is the coverage.

First, classify the property: secondary or seasonal

Every later rule hangs off one classification, and insurers draw the line by how the property is actually used:

There is a second classification inside the first. Cottage policies themselves come in seasonal and year-round versions: a seasonal policy is designed for part-year use with its vacancy conditions built in, while a year-round policy may carry less restrictive vacancy conditions and generally costs more. An owner who insures a three-season cottage on the wrong side of either line has not bought slightly worse coverage — they have bought a contract written for a different property.

The vacancy clause, condition by condition

Most Ontario cottage policies, per one specialist brokerage's clause-by-clause breakdown, contain a seasonal vacancy clause that engages after an extended unoccupancy — typically defined as more than 30 to 60 consecutive days. Wording varies by insurer, but the conditions cluster into four:

• Winterization of plumbing. Water systems drained and the water supply shut off before the winter vacancy begins. Some policies specify that a qualified professional must do the winterization, or that the owner must be able to demonstrate it was done properly.
• Utility shutoffs. Beyond water, some policies require gas turned off at the meter, or electrical service disconnected or minimally maintained — kept on, for example, where heat tape needs power.
• Inspections. Someone inspects the property at defined intervals during the vacancy — often every 30 days under these clauses — and the inspections are documented. For a remote cottage, that interval is a logistics problem to solve in October, not a surprise to discover in February.
• Notification. Some policies require the owner to notify the insurer when the property enters seasonal vacancy. Less common than it used to be, the same breakdown notes — and worth one question to a broker, because a missed notification is a cheap condition to have failed.

Read the four as a set. They describe a property that has been deliberately put to sleep: no water under pressure, no unnecessary services live, a human being walking through on a schedule, and an insurer who has been told.

Why the check-in numbers disagree: two regimes, not one rule

Search for how often a cottage must be checked in winter and the answers collide: every 30 days in one guide, every 3 to 7 days in another, 7, 14, or 30 days in a third. The collision resolves once the two regimes are separated:

• The drained property. A seasonal cottage that has been winterized — water off, lines drained, heat off — sits under the seasonal vacancy clause. Its published inspection interval is the long one: often every 30 days. There is no pressurized water to flood the building and no furnace to fail, so the clause watches mainly for intrusion and visible damage.
• The heated property kept ready. A winterized-for-use cabin or secondary home that stays heated and plumbed all winter sits under unoccupancy conditions instead: heat maintained above freezing, and check-ins often every 3 to 7 days during winter, because a furnace failure becomes a burst-pipe loss on a short clock. One cottage guide puts the general shape plainly: summer-only properties may allow longer unattended periods if the plumbing is shut down entirely, while winterized cabins with active heating face stricter inspection requirements.

The decision framework follows directly. Decide which property you actually have in January — drained and asleep, or heated and ready — then find the interval your own wordings attach to that state. Quoting the 30-day figure for a heated cottage, or paying for weekly checks on a drained one, are the same error in opposite directions: a number borrowed from the wrong regime.

Which losses the clause actually touches

A failed condition does not void the whole policy, and treating it as all-or-nothing misreads the clause in both directions. Per the clause breakdown, the conditions typically govern specific categories of loss — most commonly water damage from burst pipes, and theft or vandalism. If pipes burst because the property was not properly winterized and the policy carries a winterization condition, the insurer may deny that claim or apply a significant deductible. Some policies likewise limit theft coverage when a property has been vacant beyond the defined period without the required inspections.

Other losses stand apart from the clause. A fire loss, for example, is typically covered even during seasonal vacancy, as long as the owner has not done something that directly caused or contributed to it — leaving a propane heater running unattended is the breakdown's example. Layer the seasonal form's own shape on top: a named-perils seasonal policy generally excludes theft, vandalism, and certain water damage in the first place, in season and out. The clause narrows what the form grants; it does not narrow what the form never granted.

The close-up procedure, step by step

This topic does suit a procedure, because the sources describe the same closing sequence:

1. Confirm the classification and the clause first. Before touching a valve, establish whether the policy is seasonal or year-round, what its vacancy period is, and which conditions and inspection interval it names. The procedure serves the clause, not the other way round.
2. Shut off the water supply at the main valve, then drain all water lines and the hot water tank, so no pressurized water remains in the building.
3. Deal with the other services as the clause directs: gas off at the meter where required, non-essential electricity disconnected, and anything the policy wants minimally maintained — heat tape is the usual example — left powered deliberately, not by oversight.
4. Secure the property: lock and check every entry point, and remove or store the valuables the seasonal form is least likely to cover anyway.
5. Arrange the inspections before you leave, with a neighbour, caretaker, or property management service, at the interval your clause names — and agree how each visit gets documented.
6. Keep the evidence file: photos of the drained system and shutoffs, a plumber's receipt if a professional did the work, and a dated checklist. If a claim is ever questioned, that file is the answer.

What success looks like: on the day you lock up, you could hand an adjuster a dated record showing the water off and drained, the services set as the clause requires, the entry points secured, and a named person scheduled to walk through at the clause's interval — with your insurer notified, if your policy asks for it.

When the classification stops being true

Classifications describe use, and use drifts. The clause breakdown names the trigger directly: if your use patterns have changed — winter visits for snowmobiling, a gradual slide into year-round use — the policy classification may need to be updated to match. The same drift runs in reverse: a secondary home that stops being visited through the winter has become, functionally, a seasonal property insured as something else. And where a residence crosses into being considered vacant, one insurer's guidance is blunt: different rules apply, and the insurer must be notified promptly. The cheapest moment to fix a classification is a calm phone call in the off-season. The most expensive is inside a claim for a January loss, with the file showing a property the contract never described.

The one document to read before the first frost

Not the declarations page — the vacancy clause in the wordings, with a pen. Mark the vacancy period, the winterization wording, the inspection interval, and any notification requirement, and check each against how the property will actually spend this winter. Four markings, one hour, in October. That reading is the whole job; everything else here is what the markings tell you to do.

General information only — not insurance advice. This site is not a broker, agent, or insurer. Vacancy conditions, classifications, and covered perils vary by insurer and policy, and every claim turns on its facts and the policy wording. Talk to a licensed insurance professional about your situation, and treat your own policy document as the final word.
