Ontario Cottage Closing Checklist for Fall

Closing the cottage is rarely one big job. It is a collection of small jobs that protect the property, keep animals out, prevent unpleasant surprises and make opening weekend easier next spring.

The best approach is to work from a written Ontario cottage closing checklist and assign each item to a person. Start with the systems that need planning, then move through food and gear, security and one final room-by-room walk-through.

1. Decide what will stay powered

Before touching breakers or appliances, decide whether the cottage will remain powered through winter. The correct sequence depends on the property, heating equipment, water system, insurance requirements and whether anyone will check the cottage during the off-season.

Hydro One’s seasonal cottage closing checklist provides separate steps for cottages that will keep power on and those that will turn it off. It recommends emptying the fridge, addressing the water system and switching off only the circuits or main breaker appropriate to the chosen plan.

Follow the instructions for your specific equipment. If you are uncertain about plumbing, heating, propane or electrical work, use a qualified professional rather than improvising.

2. Empty the fridge, freezer and cupboards

Start with a simple rule: if it can spoil, leak, freeze, attract an animal or be forgotten until spring, take it home.

• Move refrigerated and frozen food into a properly packed cooler for the drive.
• Remove pantry food, pet food, cooking oils and strongly scented items.
• Empty, clean and dry the fridge and freezer.
• Leave appliance doors safely propped open for airflow after they are switched off.
• Check drawers, backpacks, tackle boxes and vehicles for snacks or garbage.

FOCA’s cottage closing guidance also advises removing food and anything that may attract animals. Ontario’s Bear Wise guidance recommends taking precautions when closing a cottage or leaving it between stays.

3. Clean and dry coolers, drinkware and outdoor gear

A cooler that is packed for the trip home should be emptied as soon as you arrive. Wash it according to its care instructions, rinse it thoroughly and let every surface dry before storage. Trapped moisture and food residue are what create most off-season odour problems.

Our detailed guide explains how to clean a cooler and store it for the off-season. The short version is straightforward:

• Remove loose debris and all food residue.
• Clean the body, lid, gasket, drain and accessories as applicable.
• Allow the cooler to dry completely.
• Store it clean, empty and ventilated in a dry location.

Empty reusable drinkware too. Wash the vessel and removable lid parts, dry them fully and store them unsealed so moisture is not trapped inside. Bring home towels, blankets and soft cooler bags unless the cottage has a reliably dry, secure storage area.

If the drive home has outgrown your current setup, compare the available Chilly Moose coolers and insulated drinkware by size and intended use before the next trip.

4. Prepare the water system for freezing temperatures

Hydro One’s checklist calls for turning off the water pump and water heater and draining the water tank and pipes when closing a seasonal cottage. The exact work varies widely between properties, especially where there are pumps, filters, dishwashers, washing machines, exterior lines or septic systems.

Write the water-system procedure for your own cottage and keep it with the shutoff locations, equipment manuals and service contacts. If the system has not been professionally winterized before, this is the part of the closing weekend where expert help can prevent an expensive mistake.

5. Remove attractants and secure the property

A clean building is easier to protect. Take home garbage, recycling, alcohol, valuables and portable outdoor gear. Secure windows and doors, store sporting equipment and record what remains at the property.

FOCA notes that seasonal properties are especially vulnerable during the off-season following Thanksgiving. Its guidance recommends securing access points, recording valuable items, arranging a keyholder and building a neighbour network that can notice damage or suspicious activity.

Before leaving, confirm that smoke and carbon monoxide alarms are working as required for the way the cottage will be used and monitored. Check the property’s insurance requirements as well; a seasonal building may have inspection, heating or vacancy conditions that are specific to the policy.

6. Create a winter contact plan

Choose a local contact who can access the cottage after a storm, alarm, outage or call from a neighbour. Share:

• keys and alarm instructions;
• water and electrical shutoff locations;
• your preferred plumber, electrician and property service contacts;
• insurance contact details;
• where emergency supplies are stored; and
• the best way to reach you.

If the power stays on, consider the outage and usage alerts available through your electricity provider. A sudden change in use can be an early sign that something at the property deserves attention.

Final cottage closing walk-through

• Kitchen: food removed; fridge and freezer emptied, cleaned and left open as appropriate.
• Water: pump, heater, tanks, fixtures and connected appliances handled according to the cottage’s winterizing plan.
• Power: circuits and appliances set according to the confirmed power-on or power-off plan.
• Gear: coolers and drinkware empty; textiles and soft gear clean and dry.
• Wildlife: garbage, food, pet supplies and other attractants removed.
• Security: valuables removed; windows, doors, sheds, boats and outdoor equipment secured.
• Safety: alarms, insurance requirements and monitoring arrangements checked.
• Handoff: keyholder and neighbours have the information they need.

Take photos of each room, the shutoffs and the exterior before you leave. Save the checklist, photos and notes in one place. Next spring, the same record becomes your cottage-opening plan.
