Start with the physical reality of the home. Hamilton has a lot of raised-porch bungalows and split-levels, especially through the mountain neighbourhoods and older east-end streets, and those few steps are exactly where a vertical platform lift earns its keep. Measure the travel height and be honest about who will use it and what they'll bring aboard, a wheelchair plus a caregiver adds up. Match the weight capacity to that, not to the smallest number that technically fits.
The bigger decision here is indoor versus outdoor. If the lift serves a front or side entrance, get a weather-rated outdoor unit. Hamilton gets freeze-thaw cycles, escarpment wind, and salt spray near the harbour, and an indoor-grade unit exposed to that will corrode and act up. It costs a little more up front, but a lift that fails in February is worse than one you paid slightly more for. On the flip side, if the lift is fully indoors, don't overpay for outdoor hardening you'll never need.
When you compare installers, prioritize ones with real accessibility experience over a general handyman or a lower quote. This is a permanent, load-bearing install with electrical and safety gates involved, and the cost of vertical platform lifts in Hamilton is small next to a bad installation. Confirm the company is licensed and insured, ask about the warranty on both the motor and the structure, and pin down service response time, because a lift you can't get serviced quickly isn't much use. Ask specifically about safety gates, the controls your parent can actually operate, and battery backup for our fairly frequent winter power blips.
Our honest recommendation: pay for a proper professional installation from an accessibility specialist rather than the cheapest bid. The trade-off is a higher price and sometimes a short wait for the right crew, but you get code-compliant work, a real warranty, and someone who'll come back when something needs adjusting.
