Pricing for a home stair lift in Ontario depends almost entirely on one factor most people don’t think about until they’re already shopping: the shape of their own staircase. A straight run of steps and a staircase with a landing or a curve are two completely different projects, priced very differently, and understanding that difference upfront saves a lot of confusion when the quotes start coming in.
This guide breaks down straight versus curved stair lifts, what each realistically costs in 2026, the tax credits that can offset the price, and how to choose an installer who will get the fit right the first time.
Straight vs. Curved: The Decision That Sets the Price
Straight Stair Lifts
A straight stair lift runs along a staircase with no bends, turns, or landings. Because the rail comes in standard lengths that fit most residential staircases, straight lifts are manufactured to stock specifications and can typically be measured, ordered, and installed within days.
Curved Stair Lifts
A curved stair lift is required whenever a staircase has a landing, a turn, or a change in width partway up. Every curved rail is custom-built to trace the exact geometry of that specific staircase, which means more engineering time, a longer lead time between order and installation, and a meaningfully higher price.
Stair Lift Installation Cost Ontario Homeowners Should Expect in 2026
| Staircase Type | Typical Installed Cost |
|---|---|
| Straight stair lift | $3,000 – $6,000 |
| Curved stair lift | $10,000 – $18,000+ |
| Refurbished/used straight unit | $2,000 – $3,500 |
The biggest driver within either category is staircase length — a longer run of stairs needs more rail — followed by seat and safety options like a power swivel seat, folding rail, or a higher weight capacity. Outdoor stair lifts, where weatherproofing adds to both the unit and the installation, typically run higher than an equivalent indoor model.
What Affects the Final Quote
- Staircase length: More steps mean more rail, which increases both material and labour cost
- Weight capacity: Higher-capacity lifts use larger motors and heavier-duty components
- Seat and safety options: Power footrests, swivel seats, and padded upholstery add to the base price
- New vs. refurbished: A refurbished straight unit can meaningfully lower cost for a budget-conscious project
- Ongoing maintenance: Battery replacement every 3–5 years and occasional service calls are worth budgeting for after installation
Tax Credits That Can Offset the Cost
The federal Home Accessibility Tax Credit (HATC) allows a qualifying individual — someone 65 or older, or eligible for the Disability Tax Credit — to claim 15% of up to $20,000 in eligible accessibility renovation expenses, for a maximum credit of $3,000 per year. A stair lift generally qualifies as long as it’s a permanent installation integral to the home. (See our full guide to the Ontario Home Accessibility Tax Credit — internal link) For larger accessibility projects, the Home and Vehicle Modification Program can also apply, though eligibility there is based on documented mobility restrictions rather than age alone.
Choosing an Installer for Your Stair Lift
Not every mobility equipment dealer offers the same brands, warranty terms, or installation timelines, and curved rail projects in particular depend heavily on the manufacturer’s local support. When comparing quotes, ask directly about the brand’s warranty coverage, whether the installer stocks parts locally, and how quickly a technician can respond if something needs adjusting after installation.
In-Trend Home Solutions installs and maintains stair lifts, vertical platform lifts, ceiling track lifts, and home elevators across London, Cambridge, and Etobicoke, working directly with occupational therapists and case managers to match the right lift to the staircase and the person using it.

The Bottom Line on Stair Lift Installation Cost Ontario Families Face
A straight staircase is the more affordable, faster path to installing a stair lift, while a curved or landing staircase requires a custom rail and a meaningfully larger budget. Either way, checking eligibility for the HATC before committing to a quote is worth the ten minutes it takes, since it can put a real dent in the final cost.
