Start with the two numbers that decide everything: travel height and weight capacity. A raised porch in Old Ottawa South needs a very different lift than a full storey inside a split-level in Alta Vista. Measure the vertical rise honestly, and factor in the rider plus their wheelchair or scooter, not just body weight. If the lift will live outside, and many Ottawa entrances do, insist on a weather-rated outdoor unit. Our winters bring freeze-thaw cycles, road salt, and heavy snow load, and an indoor-grade platform left exposed will corrode and stall far sooner than it should.
Prioritize installers with real accessibility experience, not general contractors who occasionally touch lifts. Ask whether they hold the proper licensing and liability insurance, and confirm who handles service calls once the lift is in. A lift that quits in February is only as good as the company's response time, so a local Ottawa presence matters more than a lower quote from someone hours away. Check the warranty on both the motor and the structure, and ask about backup power. When the grid drops during an ice storm, battery backup is what gets your parent safely down to the door.
Our honest recommendation: for outdoor entries here, pay for the weather-rated unit with a covered or partially enclosed platform, even though it costs more than a bare indoor-style model. The trade-off is a higher upfront price. But in Ottawa's climate, the cheaper indoor lift becomes a maintenance headache and a safety risk, and you'll spend the savings on repairs within a few winters. Spend once, install it properly, and have it serviced before the cold sets in. If your parent's needs are still changing, talk with the installer about a shaft-ready or enclosed option so you aren't tearing things out in a year.
