Why Winter Maintenance Is Non-Negotiable for Ontario Landlords
Ontario winters are not gentle. From Belleville to Cobourg, landlords managing residential rental properties face months of freezing temperatures, heavy snowfall, ice storms, and the kind of cold that finds every gap in an aging building envelope. For landlords, winter is not just an inconvenience. It is a legal responsibility, a liability exposure, and a direct test of your relationship with your tenants.
Under the Residential Tenancies Act (RTA), Ontario landlords are required to maintain rental units in a good state of repair and fit for habitation. That obligation does not pause when the temperature drops. In fact, winter is when that duty is tested most aggressively. Falling short can mean Landlord and Tenant Board applications, rent abatements, or worse. The good news is that a proactive winter maintenance plan protects your property, your tenants, and your bottom line all at once.
This guide is designed for landlords managing long-term residential rentals in Central Ontario. Whether you self-manage or work with a property management company, these are the steps that matter most once the cold sets in.
Your Legal Heating Obligations
Let us start with the most legally sensitive issue: heat. Ontario law requires that rental units be heated to a minimum of 20 degrees Celsius from September 1 through June 15. Many municipalities, including Belleville and Quinte West, have their own bylaws that may set even stricter standards or extend the heating season. Landlords who supply heat as part of the tenancy are responsible for ensuring the system functions reliably throughout winter.
Before the cold arrives, every furnace, boiler, or heat pump should be inspected and serviced by a licensed HVAC technician. Filters should be replaced, venting should be cleared, and thermostats should be tested. If you manage multiple units, do not wait for a tenant complaint to find out your heating system is struggling. A mid-January furnace failure at 11 PM is expensive, stressful, and a potential RTA violation all at the same time.
It is also worth confirming that your tenants know how to operate the heating system, especially if they are new to the unit. A brief written note or welcome message at the start of the season can prevent misunderstandings about who is responsible for what.
Winterizing the Building Envelope
Heat retention starts with the building itself. Before temperatures drop consistently below zero, landlords should walk their properties with a critical eye for air leaks, damaged weatherstripping, and failing caulking around windows and doors. These are inexpensive fixes that make a meaningful difference in both comfort and energy costs.
Attic insulation is worth checking if you have not done so recently. In older Central Ontario housing stock, inadequate attic insulation is one of the most common contributors to ice dams, which form when heat escapes through the roof and causes snow to melt and refreeze at the eaves. Ice dams can cause serious water damage to ceilings, walls, and insulation. Addressing insulation before winter is far cheaper than repairing the aftermath.
Exterior pipes and hose bibs should be shut off and drained before the first hard freeze. Remind tenants to disconnect garden hoses, and if your property has any exposed plumbing in unheated spaces like garages or crawl spaces, those areas need extra attention. A burst pipe in a rental unit is one of the most disruptive and costly winter emergencies a landlord can face.
Snow Removal and Ice Control: Who Is Responsible?
The lease agreement and local bylaws determine who handles snow removal, but landlords need to be clear on this point before winter arrives. In many Ontario municipalities, property owners are legally responsible for clearing sidewalks adjacent to their property within a set timeframe after snowfall. Failing to do so can result in fines, and more importantly, liability if someone is injured on an icy walkway.
If you are including snow removal as part of the tenancy, make sure you have a reliable contractor lined up before the first snowfall of the season. Waiting until after the first storm to find a plow service means competing with every other landlord and homeowner who did the same thing. Contracts with snow removal companies should be signed in the fall, with clear expectations about response times, salting, and sanding.
If snow removal is the tenant's responsibility, this must be explicitly stated in the lease. Even then, landlords should monitor the property to ensure it is being maintained safely. A tenant who consistently fails to clear ice from walkways creates a liability issue that ultimately lands on the property owner.
For multi-unit buildings, the landlord is almost always responsible for common areas. Parking lots, shared walkways, and building entrances need to be cleared promptly and treated with sand or ice melt to reduce slip-and-fall risk.
Plumbing, Pipes, and Preventing Freeze-Ups
Frozen pipes are one of the most preventable winter emergencies, yet they remain common in older Ontario rental stock. Properties with plumbing on exterior walls, in unheated basements, or in poorly insulated crawl spaces are most at risk. Pipe insulation is inexpensive and straightforward to install, and it is a worthwhile investment for any landlord managing older properties.
Tenants should be informed about how to prevent freeze-ups in extreme cold. Keeping cabinet doors under sinks open on very cold nights, allowing a slow drip from faucets on exposed pipes, and keeping the heat at a minimum temperature even when they are away are all practical steps. Consider including a simple winter tips sheet in your fall communication to tenants.
If a unit will be vacant during winter, take extra precautions. The heat should remain on at a minimum of 15 degrees Celsius, all water supply lines should ideally be shut off and drained, and the property should be checked regularly. A vacant unit in January with a failed furnace can result in catastrophic pipe damage within hours.
Roof, Gutters, and Drainage
Gutters clogged with leaves and debris from fall will trap water and ice through winter, leading to ice dams, overflow, and potential water infiltration into the building. Cleaning gutters in late October or early November, before the freeze sets in, is one of the most cost-effective preventive maintenance tasks a landlord can complete.
Roofs should also be inspected annually, ideally before winter. Missing or damaged shingles, compromised flashing around chimneys and vents, and worn sealants around skylights are all vulnerabilities that become serious problems under snow load and freeze-thaw cycles. Catching a minor roof issue in October costs a fraction of what it costs after a February ice storm has had its way with it.
Communicating With Tenants Through the Winter Season
Good communication is one of the most underrated tools in winter property management. Tenants who feel informed and supported are more likely to report maintenance issues early, before small problems become large ones. A simple message at the start of the season reminding tenants of how to report heating issues, who to contact for emergencies, and what their responsibilities are goes a long way.
Encourage tenants to report drafts, unusual sounds from the furnace, or signs of water infiltration immediately. Many tenants hesitate to report issues because they worry about being a nuisance or do not realize the issue is serious. Making it clear that early reporting is always welcome protects everyone.
At Blue Anchor Property Management, we use Rentvine as our property management platform, which gives tenants an easy way to submit maintenance requests through the tenant portal at any time. When a heating issue or water concern comes in, our team coordinates the appropriate contractor quickly. Tenants also have access to their lease documents and payment history through the portal, keeping communication organized and transparent throughout the year.
Seasonal Inspections: Your Best Defense
A pre-winter property inspection, conducted in September or October, is one of the most valuable habits a landlord can develop. Walking the property with a checklist that covers heating systems, weatherproofing, plumbing vulnerabilities, roof condition, gutters, exterior lighting, and emergency access gives you a clear picture of what needs attention before conditions become dangerous.
Document everything with photos and written notes. This serves two purposes: it helps you prioritize repairs, and it creates a record of the property's condition that can be useful if a dispute arises later in the season.
