The investor case for Erin, Ontario
Erin is a town that couldn’t grow and now can. Here’s the full picture: the numbers that make it interesting, the risks that should keep you careful, and the strategies that fit.

A town that couldn’t grow, now can
Erin Village and Hillsburgh had no municipal sewers, so new housing needed large septic lots. That held Erin’s population almost flat: 11,439 in 2016, 11,981 in 2021. The new wastewater system, funded mainly by developers and now in final commissioning, removes that cap.
With servicing, Wellington County plans for Erin Village to grow from about 3,100 to 10,800 residents and Hillsburgh from 1,400 to 6,100 by 2051. Six communities are already approved or in approvals.
How the wastewater project unlocks growth
Commuter families with GTA incomes
Erin’s households are large (2.8 people on average) and affluent: average household income was about $177,700 in 2025, well above Wellington County and Ontario. Residents mostly commute out to Brampton and Peel, Halton Hills’ Premier Gateway employment lands, Guelph and Orangeville, all within about 25–45 minutes.
Building activity shows the shift: Erin issued 247 new residential permits in 2025, the most of any Wellington municipality, as Erin Glen filled with 840+ families.

The lowest new freehold prices in the area
Erin Glen’s September 2026 prices are about 20–25% below its own 2021 launch pricing (towns then started in the “high $700s”). They also sit below new-construction starting prices in every neighbouring town we track.
See the full comparisonNew-home starting prices, 2026. Erin: Solmar’s Erin Glen price list (Sept 23, 2026), shown with an HST credit applied that depends on buyer eligibility. Other towns: indicative starting prices from builder and new-home listing sources; they vary by project, lot and incentives. Not an appraisal or offer. Verify current pricing with each builder.
A buyer’s market, plus a deadline
Erin’s resale market has cooled hard, and that cuts both ways.
Erin resale has come down
| Year | Avg price, Erin Village + Hillsburgh |
|---|---|
| 2023 | $1,201,451 |
| 2024 | $1,106,610 |
| 2025 | $1,044,284 |
| H1 2026 | $846,205 |
TRREB community reports; averages are not mix-adjusted, and 2026 includes more Erin Glen towns and semis. Wahi reported about 16 months of inventory in September 2026, a strong buyer’s market.
Why that can be an opportunity
- Negotiating leverage: builders are offering incentives (Erin Glen currently includes appliances, a basement rough-in and waived closing levies).
- Up to $130,000 HST relief on new homes for agreements signed by March 31, 2027, including rental properties.
- Long closings: pre-construction lets you lock today’s price and pay deposits over time, closing 18–36 months out.
Thin rental supply, family-sized demand
Only about one in ten Erin households rented in 2021, so there’s little purpose-built rental stock. Fall 2026 listing snapshots show:
| Home | Typical asking rent |
|---|---|
| New freehold townhome (Erin Glen) | $2,800 – $3,000 |
| 3–4 bedroom detached, in town | $3,000 – $3,500 |
| 1–2 bedroom unit (Ontario estimate, existing tenancies) | $1,600 – $1,800 |
Listing snapshots (Royal LePage, Kijiji, Oct 2026) and Ontario’s 2026 average market rent bulletin for Erin. Indicative only; not an appraisal of rental value.
On serviced urban lots, Ontario permits up to three units per lot as of right, so a legal basement suite can add meaningful income. Ask builders about side entrances and rough-ins before signing.
Model rent and cash flow
What could appreciation look like?
Nobody knows. For context, here’s how Erin’s neighbours moved over the last decade (TRREB MLS® HPI composite benchmarks, August of each year):
| Market | 10 yrs | 5 yrs |
|---|---|---|
| Halton Hills (Georgetown/Acton) | +61.5% | −8.6% |
| Brampton | +57.5% | −6.6% |
| Orangeville | +53.4% | −13.6% |
Erin has no long-run benchmark series. Benchmarks are model-based “typical home” values.
Illustrative scenario from our 2026 presentation
Illustrative scenario only, not a forecast or guarantee. It applies hypothetical growth rates of 10–15% over three years and 15–25% over five years to a $599,900 Erin Glen townhome starting price. Erin resale prices have fallen since 2023, and neighbouring markets are still below their 2021–22 peaks. Values can go down as well as up. This is not financial advice; do your own analysis or use our calculator with your own assumptions.
The risks we’d want you to know
Servicing delays
The wastewater plant’s completion has slipped repeatedly since 2024, and new plans can’t register without confirmed capacity. Hillsburgh plans also need a new municipal well. Launches and closings can move.
Lots of new supply
Thousands of similar homes over the next decade means you’ll compete with builders and other investors at resale and for tenants. Lot, model and phase choice matter.
Prices can fall
Erin resale averages are down since 2023. If you need to sell or assign before the market recovers, you could lose money. Underwrite as a long-term hold.
Rates & appraisals
Your mortgage rate is set at closing, not signing, and the home must appraise for your lender. Budget for a higher rate than today.
It’s a commuter town
Erin has no major local employers and no fixed-route transit. Tenant demand depends on people willing to drive 25–45 minutes to work or a GO station.
Contract terms
Freehold homes have no cooling-off period, and assignment rights, closing adjustments and HST clauses vary. Have a lawyer review before you sign.

Who Erin suits
Buy, rent and hold
An entry-level townhome or a detached home with a legal suite, held 5–10 years as Erin’s population and amenities fill in. Use the HST relief to cut your cost base.
First home, with income
First-time buyers can stack federal and Ontario rebates (up to $130K) and use 30-year amortization. Live upstairs, rent the basement once permitted.
Early-phase positioning
Register for first releases in Hillsburgh and on the Eighth Line, where early phases tend to get the best pricing and lot selection.

Investing in Erin: questions
Is Erin, Ontario a good real estate investment in 2026?
Erin’s long-term case rests on three things: new wastewater servicing that allows growth for the first time, a County forecast that more than doubles the population by 2051, and new-home prices below surrounding GTA-fringe towns. The short-term picture is softer: Erin resale prices have fallen since 2023 and inventory is high, which gives buyers negotiating leverage but means values could keep falling. It suits long-term holders more than quick flips.
What do rentals go for in Erin?
Listing snapshots from fall 2026 show new freehold townhomes in Erin Glen asking about $2,800–$3,000 a month and 3–4 bedroom detached homes about $3,000–$3,500. Renters make up only about 10% of Erin households (2021 Census), so rental supply is thin.
Can I add a rental suite to a new home in Erin?
Ontario allows up to three units per lot as of right on urban residential land with municipal water and sewer, and the extra units are exempt from development charges. Once Erin’s urban lots are serviced, that applies, but zoning details, the Building Code and builder agreements still govern. Ask about a separate side entrance and basement rough-ins before you buy.
What are the biggest risks of investing in Erin pre-construction?
Servicing delays (the wastewater plant’s schedule has slipped several times), a large wave of new supply competing for buyers and tenants, a current buyer’s market, rising carrying costs if rates move, and builder closing delays. Underwrite every purchase as a long-term hold.
