Newmarket real estate guide 2026: market, neighbourhoods and what’s being built

At a glance: Newmarket’s growth is planned around Yonge and Davis, where the Upper Canada Mall master plan and the Urban Centres plan target 33,000 residents and 32,000 jobs over the long term. In August, homes here sold at 99% of list price, the tightest ratio in York Region.

Checked on 3 October 2026 against TRREB, municipal, regional, provincial and Metrolinx sources. Anything I could not confirm on an official page is left out or labelled.

Where to live in Newmarket

• Yonge–Davis / Upper Canada Mall: Urban growth centre with emerging mid- and high-rise. Suits first condo buyers and Southlake staff.
• Historic Main St: Character homes and small commercial.
• Stonehaven / Glenway: Established detached homes for families.

Neighbourhood notes are my professional view, not official data.

What’s approved and being built in Newmarket

Only projects with an official source are listed, with the exact stage each has reached. “Approved” means a planning decision; it is not a construction start. Where a building permit has been issued, that is the strongest sign a project is actually starting.

Project	What	Stage (official)	Transit
Upper Canada Mall master plan	Mall redevelopment phased over 30–40 years	Recommended for adoption Nov 2021; regional approval and phase-1 zoning not confirmed	Yonge and Davis Viva, Newmarket bus terminal
Urban Centres plan (Yonge St & Davis Dr)	About 290 ha; target 33,000 residents and 32,000 jobs	Adopted; technical amendment pending regional approval	Viva rapidways

Newmarket has no large project with a confirmed 2026–2028 start. Treat tower supply here as a slow, long-range change.

For a GTA-wide view of what is permitted and under construction, see the GTA developments tracker and mall and plaza redevelopments.

Transit: running today vs. coming later

• Viva rapidways: the 33.7 km network was finished in Dec 2020 (Hwy 7, Yonge, Davis Dr, Bathurst & Centre). Metrolinx
• Barrie GO line serves the town. No official 2026–2028 service increase was found for this station, and proposed new stations at Kirby and Mulock have no current official status.

Taxes and closing costs in Newmarket

2026 residential property tax rate: 0.919045% of assessed value (local 0.373633% + York Region 0.392412% + education 0.153000%). Official 2026 rates. Taxes are charged on MPAC’s assessed value, which is usually well below today’s market price, so ask for the property’s actual tax bill.

• Ontario land transfer tax applies (no municipal land transfer tax outside Toronto). First-time buyers can claim up to $4,000 back if they qualify. Ontario

Buying new? Read the Ontario pre-construction buyer guide for the 2026 HST rebates (up to $50,000 federal for first-time buyers, and Ontario relief on the provincial part).

For business owners and commercial tenants

Commercial corridors: Davis Dr, Yonge St and Main St.

• Incentives in the Urban Centres: development charge deferral (36–48 months), reduced parking and the Historic Downtown community improvement plan. Current intake not confirmed; ask the Town.

Schools in Newmarket: how to check rankings and boundaries

School zone is one of the first things Newmarket buyers search for, and one of the easiest things to get wrong. A listing that says “in the X school zone” is not a guarantee. Here is how I check it for clients before they offer.

Who runs the schools: English public schools in Newmarket are run by the York Region District School Board (YRDSB), English Catholic schools by the York Catholic District School Board (YCDSB). French-language schools are run by Conseil scolaire Viamonde (public) and Conseil scolaire catholique MonAvenir (Catholic).

1. Use the board’s own school locator with the exact address, not the listing description. Boundaries follow streets, and two sides of the same street can go to different schools.
2. Check results from two sources: EQAO publishes each school’s provincial test results, and the Fraser Institute ranks Ontario elementary and secondary schools at compareschoolrankings.org. Rankings measure test scores, not the whole school, so visit too.
3. Ask about “holding schools”. When a local school is full, new students in growing areas can be directed to a school farther away until space opens. This matters most in new subdivisions.
4. Programs have their own boundaries. French Immersion, IB, gifted and arts programs often draw from a different area than the home school, and some need an application.
5. Get it in writing before you waive conditions. Boundaries can change. Call the board’s planning or admissions office with the address, and keep the answer.

Want homes in a specific Newmarket school zone? Tell me the school and your budget. I check each home’s address against the board locator before I send it to you.

Selling or buying in Newmarket: how I would approach it

Selling: price against the homes a buyer will actually compare with yours (same type, condition and recent enough), not the area average above. Then work out what you would keep after the mortgage payout and costs.Buying: decide what matters more, existing transit or a project that is only approved, and check the stage of anything near the address before you firm up.
