Top 10 Things to Look for When Touring a Home in Ontario: A Buyer’s Walkthrough Checklist

Knowing what to look for when viewing a home in Ontario can mean the difference between a sound investment and a costly mistake. A home showing is not a casual visit - it is your best opportunity to assess a property’s true condition, identify potential red flags, and gather the information you need to make a confident offer. Whether you are purchasing your first property or your fifth, walking through a home with a structured checklist dramatically improves your ability to evaluate what you are buying.

Fardad Farhanian, Broker at RE/MAX REALTRON REALTY INC., Brokerage, has guided buyers through thousands of property showings across the Greater Toronto Area and beyond over 25+ years of practice. The checklist below reflects real-world priorities that experienced buyers and brokers assess on every walkthrough.

1. The Roof and Attic Condition

The roof is one of the most expensive components of any home to repair or replace. As of 2026, a full roof replacement in Ontario typically costs between $8,000 and $25,000 depending on materials and home size. During your walkthrough, look for missing, curling, or uneven shingles from outside. Inside, check the attic for daylight penetration, water staining, mold, or inadequate insulation. Ask the listing agent when the roof was last replaced and whether documentation is available.

2. Foundation and Basement Integrity

Foundation issues are among the most serious red flags when buying a house in Ontario. In the basement, look for horizontal cracks in concrete block walls, white efflorescence (mineral deposits left by water), musty odors, or evidence of active water intrusion. Check corners and the base of walls where the floor meets the foundation. Vertical hairline cracks are often normal settling, but horizontal or stair-step cracks warrant further investigation by a structural engineer. Never skip a professional home inspection when foundation concerns are present.

3. Water Damage, Staining, and Moisture

Water damage is one of the most common - and most concealed - problems in Ontario homes. Run your eyes along ceilings, around windows, and beneath sinks on every floor. Bubbling paint, brown rings, soft drywall, or warped flooring near bathrooms and kitchens are strong indicators of past or ongoing moisture issues. Check under the kitchen and bathroom sinks for soft cabinet floors or pipe corrosion. Look up at the ceiling in rooms below bathrooms. If fresh paint appears in isolated patches, that is worth questioning.

4. Electrical System and Panel

Outdated or undersized electrical systems are a significant safety concern and can affect your home insurance eligibility. During your showing, locate the electrical panel and note the brand and amperage. Knob-and-tube wiring or Federal Pacific / Zinsco panels are known concerns in older Ontario homes. Look for the number of circuits, whether the panel appears organized, and whether there are any signs of DIY modifications. Ask when the electrical was last updated. A licensed home inspector can provide a full assessment, but your initial observation matters.

5. Plumbing: Pipes, Water Pressure, and Drains

What to check before buying a house in Canada always includes the plumbing system, yet many buyers overlook it during a showing. Turn on multiple taps simultaneously to test water pressure. Flush toilets and observe whether they run continuously. Look under sinks for leaks, rust staining, or galvanized steel pipes (which corrode over time). Ask whether the home has copper, PEX, or older lead service lines. In homes built before 1970, lead pipes remain a possibility in some municipalities. Also ask the age of the water heater and whether it is owned or rented - rental water heaters in Ontario come with monthly fees that transfer to the buyer.

6. Heating, Ventilation, and Air Conditioning (HVAC)

A functional, efficient HVAC system is essential to comfortable and cost-effective homeownership in Ontario’s climate. Ask the age of the furnace, central air conditioner, and any heat pump components. Most furnaces have a lifespan of 15-25 years; central air conditioners typically last 10-15 years. Check whether the system is owned or rented - like water heaters, rented HVAC equipment transfers obligations to the buyer. Listen for unusual noises when the system operates, and ask to see recent utility bills to identify unusually high heating or cooling costs that may signal inefficiency.

7. Windows, Doors, and Insulation Quality

Heat loss through windows and poor insulation significantly impacts energy bills. During your walkthrough, check windows for condensation between panes (a sign that the seal has failed), difficulty opening or closing, or visible drafts around frames. Test exterior doors by looking for gaps along the frame and feeling for airflow. Ask whether windows have been replaced and, if so, whether they are double or triple-pane. In older homes, ask about insulation in the walls and attic - this is especially relevant for properties built before 1980 in Ontario.

8. Lot Grading, Drainage, and Exterior Condition

The exterior of a home tells a significant story. Walk the perimeter and observe whether the land grades away from the foundation (water should drain away, not toward the house). Check eavestroughs and downspouts for damage or disconnection - a common cause of basement water intrusion. Look at the condition of the driveway, walkways, fencing, and any retaining walls. Cracks in the driveway are cosmetic; cracks in retaining walls adjacent to the foundation deserve closer scrutiny. Also check the condition of wood siding, brick mortar joints, and window caulking.

9. Neighborhood, Street, and Surrounding Environment

A home viewing is not limited to the four walls of the property. Visit the neighborhood at different times of day if possible. Observe traffic patterns, proximity to commercial zones, noise sources (highways, rail lines, flight paths), and the general condition of neighboring properties. In Ontario, proximity to transit, schools, and green space meaningfully affects long-term market demand. Review the service areas and neighborhood guides at RealtyMan to understand market dynamics across the GTA and beyond. Fardad Farhanian serves buyers across Thornhill, Markham, Richmond Hill, Vaughan, Mississauga, and dozens of other Ontario communities.

10. Disclosure Documents and Permit History

One of the most important questions to ask at a house showing is whether all renovations were completed with proper permits. Unpermitted work - finished basements, additions, electrical upgrades - can create liability for a new buyer and complications during home inspections or mortgage appraisals. In Ontario, sellers are required to complete a Seller Property Information Statement (SPIS), though its use is voluntary. Ask your broker to review all available disclosure documents before you make an offer. Always consult a qualified real estate lawyer before finalizing any purchase transaction - legal guidance is not something to skip.

Use the mortgage calculator at RealtyMan to estimate your buying power before you begin touring homes, and browse available properties across Canada to see what is currently on the market.
