How to Close Your Ontario Cottage for the Winter

Wondering how to winterize a cottage or looking for a cottage closing checklist? Before you lock up for the season, work through these essentials. The exact steps depend on whether your cottage is heated year-round, your water system and your insurer’s requirements.

Cottage closing checklist

  • Water and plumbing: Shut off and drain seasonal water lines, pumps, tanks and fixtures as appropriate; follow the manufacturer’s winterizing instructions.
  • Heating and electricity: Set heat and power safely for your winter occupancy plan and insurance conditions.
  • Roof, gutters and exterior: Clear debris, inspect drainage and secure anything vulnerable to wind or snow.
  • Doors and windows: Lock up, check seals and make sure openings are weather-tight.
  • Pests and food: Remove perishables, store supplies securely and address likely entry points.
  • Dock, boats and outdoor items: Prepare or store equipment according to local conditions.
  • Final walk-through: Check alarms, security, access arrangements and emergency contact information before leaving.

For a fuller explanation, read our guide to closing a cottage. For a broader ownership reference, The Ontario Cottage Owner’s Handbook includes printable spring opening and fall closing checklists, plus guidance on water, septic systems, maintenance and insurance.

 

Cottage ownership in Ontario comes with its own rules

A cottage is not a house in the city with a lake view. It has its own water system, its own sewage system, often a private road, a shoreline regulated by several governments at once, and a calendar of opening and closing that decides whether pipes burst over the winter. Most of the expensive surprises cottage owners face, from a failed septic bed to a boathouse sitting on land they don’t own, are predictable, and most can be avoided with the right questions asked at the right time.

The Ontario Cottage Owner’s Handbook gathers those questions and answers in one place. It explains how things actually work in Ontario’s cottage country: who inspects a septic system, how to test well water for free, what a WETT inspection is and why your insurer wants one, how the shore road allowance can leave you without legal ownership of your own shoreline, which permits a dock or boathouse may need, and how capital gains tax can force the sale of a family cottage if nobody plans for it.

It is written in plain language for real cottage owners and buyers, not lawyers or bureaucrats, with checklists you can print and use.

Ten things to check before buying a cottage in Ontario

A preview of the kind of practical advice in the handbook. Every one of these has cost a cottage buyer real money.

  1. Do you own the shoreline? Many Ontario waterfront lots don’t run to the water. A 66-foot shore road allowance may belong to the township, sometimes with the cottage or boathouse sitting on it. Get a current survey.
  2. Is there legal road access? Private and unassumed roads are common. Find out who owns the land the road crosses, who maintains it and whether it’s plowed in winter.
  3. What condition is the septic system in? Ask the township for permits and inspection records, and have the tank pumped and inspected during your condition period.
  4. Is the water safe, and is there enough of it? Ontario offers free bacteria testing for private wells. Test more than once, and pay a lab for chemistry.
  5. Will an insurer cover it? Wood stoves usually need a WETT inspection. Old wiring, oil tanks and remote locations can limit coverage. Get a quote before you waive conditions.
  6. Are the dock and boathouse permitted? Shoreline structures can involve the township, the conservation authority, the province and, on the Trent-Severn or Rideau, Parks Canada.
  7. What can you build? Zoning, waterfront setbacks and septic capacity decide whether you can add a bunkie, winterize or expand.
  8. Can you rent it out? Many cottage townships now license or restrict short-term rentals, and unlicensed rentals can lose their tax deductions.
  9. Can you finance it? Seasonal and water-access cottages often need larger down payments. Get pre-approved for this type of property.
  10. What will it really cost each year? Budget for property tax, insurance, utilities, maintenance and a reserve for the big repairs.

Made for Ontario, not a generic guide to vacation homes

Ontario rules. Ontario Building Code septic requirements, conservation authority permits, land transfer tax, the Consumer Protection Act and Construction Act, Ontario’s Fire Code alarm rules and more.

Canadian taxes. Capital gains on a cottage, the principal residence exemption for families with a home and a cottage, deemed disposition at death, short-term rental income and HST.

Cottage country reality. Private roads, island and water-access cottages, freeze-up and break-up, lake associations, few contractors and short seasons.

Covering Ontario’s cottage regions, including Muskoka, Haliburton Highlands, Kawartha Lakes, Georgian Bay, Parry Sound, Lake Simcoe and Orillia, the Bruce Peninsula and Grey County, Prince Edward County, Frontenac and Land O’Lakes, the Rideau Lakes, the Ottawa Valley, the Almaguin Highlands, Lake Nipissing and Temagami, and Lake of the Woods.

Keeping the cottage in the family without tearing the family apart

For many Ontario families, the cottage is the most emotional thing they own, and too often the thing they end up fighting over. The handbook walks families through the conversation to have first, the options for passing on a cottage, how to plan for the capital gains tax, and what a written cottage co-ownership agreement should cover, from sharing summer weeks to buying out a sibling.
