New Construction Homes in Caledon: A 2026 Growth Guide

Caledon is where most of Peel Region's remaining greenfield growth is headed, and 2026 is the year the planning paperwork caught up with the ambition. If you are looking at new construction homes in Caledon, here is the short version: the Town has a provincially approved growth plan taking it from roughly 80,000 residents to 300,000 by 2051, the first new secondary plans are enacted into by-law, and Highway 413 is under construction across the south end of Town.

I'm Navneet Bhasin, a real estate agent with eXp Realty, Brokerage. Here is what has actually been approved, where the new communities are going, and the local checks that catch buyers off guard in a town still half rural.

Quick answer: New construction in Caledon is guided by the Future Caledon Official Plan, which the Province approved with modifications on 22 October 2025 and which plans for 300,000 residents and 125,000 jobs by 2051. The main growth areas are Bolton, Mayfield West, Tullamore and newly adopted secondary plans in south Caledon, and the Town has pledged to support 13,000 new housing units by 2031.

Key Takeaways

• The Future Caledon Official Plan was approved by the Province on 22 October 2025, replacing most of a plan dating to 1978.
• The Town pledged to support 13,000 new housing units by 2031, with 3,600 tied to Bolton's approved urban area and transit station area.
• Mount Hope West was enacted by By-law 2026-012 on 24 February 2026 and plans roughly 900 residential units.
• Highway 413 is a 52-kilometre, six-lane route from Highway 400 to the Highway 401/407 ETR interchange, and construction has started.
• Caledon's total 2026 residential property tax rate is 0.982207%, the lowest of Peel's three municipalities.

What Is Driving New Construction in Caledon?

One document, mostly. On 22 October 2025 the Minister of Municipal Affairs and Housing approved the Future Caledon Official Plan with modifications, replacing most of a plan dating back to 1978. The Town's announcement framed the scale plainly: Caledon has close to 80,000 residents and about 4,000 businesses today, and the plan sets a path toward a city of 300,000 residents and 125,000 jobs by 2051. That is a near-quadrupling of population in 25 years, and it is why builders have been assembling land in south Caledon for a decade.

The rollout is phased. Phase 1, the foundational land use policies, is in effect. Phase 2 was expected to begin in 2026, covering transit station planning, mineral aggregate policies, truck parking and an update to the Bolton Secondary Plan.

Underneath it sits the Region of Peel Official Plan, implemented by the Town since 1 July 2024, which shows a 2051 New Urban Area in south Caledon. That designation is the best predictor of where subdivision signs go up next.

Where Are New Construction Homes in Caledon Being Built?

Four names recur in the Town's own documents: Bolton, Mayfield West, Tullamore and Mount Hope West. Caledon's Growth Management and Phasing Plan, completed in November 2024, listed the first three as priorities, alongside a south-to-north servicing strategy that treats a future Caledon GO station as a key growth driver.

Here is what the Town has published for each area, and what it has not:

Where the Town publishes no unit count, I have left it blank rather than estimate one.

Mount Hope West shows what the new plans look like in practice. By-law 2026-012, enacted 24 February 2026, covers lands west of Mount Hope Road and north of Columbia Way, with Greenbelt lands to the west and north. It plans roughly 900 residential units and a population of 2,800 by 2051, about 130 commercial jobs, and a density target of 98 people and jobs per hectare. Housing is a full range of ground-related forms, including single detached and semi-detached dwellings, with transit access targeted within 400 metres of most homes.

How Highway 413 Changes the Map for Caledon Buyers

Transportation is the quiet variable in every Caledon buying decision, and it is moving. Ontario's 2026 Budget confirms construction has started on Highway 413, described as "a new 52-kilometre, 400-series highway" running from Highway 400 in the east to the Highway 401/407 ETR interchange in the west, with six lanes and protected space for a future transitway.

The Province has awarded the first two construction contracts, finished preliminary design, and has property acquisition and early works underway, including the Highway 10 and Bovaird Drive underpasses. It says the highway will cut travel times by up to 30 minutes per trip. No completion date has been published, so treat any date a listing quotes as marketing. A December 2025 Request for Proposals also covers a nine-kilometre extension of Highway 410 connecting to the future corridor.

My advice is unchanged by any of it: buy the house, the lot and the community as they exist on closing day, and treat the highway as upside, not the reason for the purchase.

What Do Caledon Home Prices Look Like in Fall 2026?

Caledon is a thin, lumpy market, and that matters more here than anywhere else in Peel. According to the Toronto Regional Real Estate Board's Market Watch report for September 2026, released 6 October 2026, Caledon recorded 64 sales across all home types at an average price of $1,070,154, against 217 new listings. Detached homes were 50 of those 64 sales, averaging $1,147,898. Peel Region as a whole posted 936 sales at an average of $906,719 that month. Caledon prices above the regional average because its housing stock skews detached and large-lot, not because the market is hotter.

Two cautions. Those are resale MLS averages, not builder price lists. And with 64 sales spread across Bolton, Caledon East, Mayfield West and rural acreage, a single month can swing on a few transactions. For a specific pocket, ask me for comparable sales on that street.

On carrying costs, Caledon's total 2026 residential property tax rate is 0.982207% per the Region of Peel's property tax policy handbook, against 1.087901% in Mississauga and 1.253381% in Brampton. On borrowing costs, the Bank of Canada target for the overnight rate has sat at 2.25% since 29 October 2025, was held on 2 September 2026, and is next announced on 28 October 2026.

What to Check Before You Buy New Construction in Caledon

This is where Caledon differs from a new build in Brampton.

Find out how the house gets its water. Peel Region owns and operates municipal wells serving Alton, Palgrave, Caledon East, Caledon Village, Cheltenham Village and Inglewood. Outside those systems, rural homeowners may be on a private well, and the Region is explicit that "property owners are responsible for the construction, maintenance, and abandonment of private wells."

Ask the same question about sewage. Where there are no sanitary sewers, disposal is the owner's responsibility. The Town requires a building permit for a new on-site system, issues a certificate of approval before construction, and inspects before any part of the system is covered. The Town's septic systems guidance recommends inspecting the tank every two years and pumping it every four. Budget for that before you fall for the lot size.

Read the phasing language. The newer secondary plans tie development to completion of external road, sewer and water works where the Town requires it, and call for a Transportation Impact Study, Climate Adaptation Plan, Fiscal Impact Study and Stage 2 archaeological assessment before subdivision registration. Those steps move closing dates.

Have a lawyer read the agreement. Pre-construction agreements run long, and the clauses on adjustments, levies, interim occupancy and the builder's right to extend closing are not boilerplate. I cannot give legal or tax advice, so get a real estate lawyer on it and a tax professional on anything with a tax consequence.

Frequently Asked Questions About New Construction Homes in Caledon

How many new homes is Caledon planning to build?

The Town pledged to support 13,000 new housing units by 2031. That total includes 6,700 units in active applications under review, 3,600 tied to the Bolton 2031 Approved Urban Area and transit station area, 1,900 additional residential units, and 800 approved without permit applications.

Is Caledon a good place to buy a new construction home?

It depends what you want from the house. Caledon offers larger lots, newly planned communities and the lowest residential tax rate in Peel at 0.982207% for 2026. The trade-offs are longer commutes today, thinner resale data, and servicing questions that do not arise in Brampton or Mississauga.

What is the average home price in Caledon right now?

Caledon's average resale price across all home types was $1,070,154 in September 2026 on 64 sales, according to the Toronto Regional Real Estate Board. Detached homes averaged $1,147,898. These are resale figures rather than builder prices, and the low sales count makes monthly averages volatile.

When will Highway 413 open?

No completion date has been published. Ontario's 2026 Budget confirms construction has started, with the first two contracts awarded and early works underway on the 52-kilometre route, and says the Province is planning to deliver it in multiple sections. Be sceptical of any specific opening year you see quoted.

Does Caledon have a GO train station?

Not yet. The Town's growth planning treats a future Caledon GO station as a key driver of its servicing strategy, and its housing pledge notes the Bolton transit station area depends on the Caledon-Vaughan GO rail service, King Street reconstruction and regional servicing projects. No in-service date is published.

Thinking About a New Build in Caledon?

Caledon over the next decade is a different proposition than Caledon over the last one. The Official Plan is approved, the first new secondary plans are law, and highway work is in the ground. It is also a low-volume market where the town-wide average tells you little about your street, and where servicing can change the cost of ownership.
