Backs onto conservation, connects to the walking trail, and gives you over 3,700 square feet of finished living space. Welcome to 17 Mason Drive in Alliston, a 4 bedroom, 5 bathroom home in the Treetops master-planned community, set on a premium lot with no sidewalk in front. The curb appeal is clean and classic, with a brick exterior, stone accents, covered entry, and double car garage. Inside, the home opens with a bright foyer, high ceilings, large windows, polished tile, rich hardwood, and a carpet-free layout. The main floor has the spaces people ask for most: a dedicated office, formal dining room, living room with fireplace, and a well-planned kitchen with quartz countertops, stainless steel appliances, upgraded cabinetry, servery, centre island, and breakfast bar. Upstairs, all four bedrooms connect to an ensuite or semi-ensuite bathroom, giving each room better privacy and function. The primary suite adds generous space, dual walk-in closets, and a private ensuite, while second-floor laundry keeps daily routines simple. The finished look-out basement feels like part of the home, not an afterthought. South-facing natural light fills the space, making it ideal for movie nights, workouts, guests, play space, or a second living area. A large storage area gives you useful space now, with potential to finish more later. Out back, the setting makes the home feel different. You get stone patio space, garden beds, room to sit and unwind, and conservation and trail access directly behind you. Treetops offers approximately 7 km of walking trails, parks, and playgrounds, with Nottawasaga Resort nearby for golf and vacation-style amenities. Highway 400 is about 10 minutes away, with easy access to Barrie and Vaughan. (id:65958)

10-item due-diligence checklist. We can pre-flight most of these for you on a CMA call.
Comparable sales
Ask for 3–5 recent solds within ~1 km and the same beds/baths so the list price has context.
Property condition
Roof age, furnace age, hot-water tank age, electrical panel size, windows. Cosmetic vs structural.
Zoning
Confirm zoning matches your intent (single-family vs duplex vs secondary suite vs commercial).
Suite legality / potential
If suited or being marketed as suited: confirm permits, separate entrance, ceiling height, egress windows.
Monthly carrying cost
Mortgage + property tax + insurance + condo fee (if any) + utilities. Compare to your max budget.
Property taxes
Confirm the annual tax amount on the current assessment — and whether a reassessment is pending.
Insurance estimate
Get a same-day quote. Older homes, knob-and-tube wiring, polybutylene plumbing, flood plains all change the number.
Commute
Drive it (or transit it) at the actual time of day you'd commute. Map ETA lies during peak hours.
Deposit and financing conditions
Deposit size, financing condition window, condition removal date, possession date — all negotiable.
Inspection considerations
Budget for a home inspector ($500–700) and any specialty inspections (sewer scope, mould, asbestos for pre-1990 builds).
Rough ballpark only. Pick a down-payment option, then tap any underlined number below to plug in your real numbers — tax, condo fee, insurance, utilities. Total updates live. Confirm with a mortgage broker before writing an offer.
Cost lines (tax, condo, insurance, utilities) are editable inline above. These two control the mortgage payment math.
Approximation only. CMHC default insurance is included when down payment is under 20%. Property tax and condo fees come from MLS when listed and may not reflect the current billing year. Suite rental income depends on permits, market rent, and vacancy — confirm with a property manager. Always validate your scenario with a mortgage broker and your insurance provider before writing an offer.
