Sonoma Heights and Islington Woods sit side by side in western Woodbridge. They share the Humber valley, the same quick run onto Highway 427 and the same school boards. They don't share a price tag. Detached homes in Islington Woods regularly trade at several hundred thousand dollars more than comparable homes next door in Sonoma Heights, and sometimes a million or more.
So the question buyers ask us is a fair one: what does that premium actually buy, and is it worth paying? Here's the honest comparison.
The Short Answer
If you want the western Woodbridge lifestyle (conservation trails, quiet established streets, a fast 427 commute) at the most sensible price, Sonoma Heights usually wins. If you want lot size, home scale or a custom or ravine property that's hard to find anywhere else in Vaughan, Islington Woods is where that product lives, and the premium is the cost of getting it.
Most buyers fall clearly into one camp once they're honest about which of those they actually need.
The Price Gap, in Real Numbers
| Sonoma Heights | Islington Woods | |
|---|---|---|
| Detached, typical range | About $1.2M to $1.7M+ | About $1.8M to $3.5M, more for premium lots |
| Detached, typical sale | Median about $1,435,000 (2023 to 2026) | $1.8M to $2.5M |
| Entry point | Condo townhouses around $790,000; freehold townhouses around $1,070,000 | Older detached or townhomes, $1.4M to $1.8M; condos $550,000 to $770,000 |
| Housing stock | Mostly two-storeys built from 1999 to the early 2000s, consistent in age | Late 1980s and 1990s homes plus newer custom builds |
At the middle of each market, the gap is roughly $300,000 to $1 million. To put that in monthly terms, every $100,000 of extra mortgage costs about $550 a month at a 4.5% rate over 25 years. A $400,000 gap is over $2,000 a month before property tax, which is also higher on a more expensive home.
The figures above come from our Sonoma Heights and Islington Woods community guides, which break each market down further.
What's Genuinely the Same
This is the part that surprises buyers, and it's why Sonoma Heights attracts so many people who started out looking in Islington Woods.
The green space. Both communities border the Humber River valley and its trail network, and conservation land is within walking distance of many addresses in each. If daily access to trails is what's drawing you to Islington Woods, Sonoma Heights gives you much of the same.
The commute. Highway 427 is the main southbound route from both, and it's minutes away from most addresses in either community. The realistic downtown drive is 30 to 45 minutes from Islington Woods and 35 to 50 from Sonoma Heights on a normal day. Neither has a GO train, and both are slower to Highway 400.
The schools. Both are served by the York Region District School Board and the York Catholic District School Board, with strong Catholic-board involvement in each. In both communities, the school your child attends depends on the specific address, so check the catchment before you write an offer.
The feel of the streets. Both are quiet, residential and largely owner-occupied. Neither has cut-through traffic or a commercial strip running through it. Day-to-day shopping happens along Islington Avenue, Highway 7 and Weston Road for both.
What the Islington Woods Premium Actually Buys
The premium isn't for nothing. It pays for three things Sonoma Heights can't offer.
Scale. Islington Woods runs large. Lots are wider, homes are bigger, and the streetscape has a sense of space you can't add after the fact. If you need serious square footage, for a multi-generational household for example, Islington Woods has more homes that fit.
The top tier. Ravine lots, premium crescents, pie-shaped lots and custom-built homes sit mostly in Islington Woods. Above about $2.5 million, you're buying something that has no real equivalent elsewhere in Vaughan. Sonoma Heights simply doesn't have that product.
The address. Islington Woods is Vaughan's most expensive neighbourhood, and its owners know what they have. Pricing is informed, homes move relatively quickly for the price range, and the community has a long record of holding its value. Part of what you pay for is that reputation.
Where Sonoma Heights Has the Edge
Value for the lifestyle. If you value the trails, the 427 and the quiet streets more than lot size, Sonoma Heights delivers most of what you want for much less.
Consistency. Because most of Sonoma Heights was built between 1999 and the early 2000s, homes are similar in age and build. That makes it easier to compare like with like and to judge what a fair price is. In Islington Woods, two homes on the same street can be decades apart in age and wildly different in finish, which makes pricing harder to read.
Stability. Around 95% of Sonoma Heights homes are owner-occupied, among the highest rates in Vaughan, and many owners have been there 15 to 25 years. Detached homes have been selling in the mid-teens of days on market. Demand is steady, and it isn't driven by trends.
The trade-off is supply. Sonoma Heights is small, and good homes don't come up often. Buyers who want it need to be ready before the right listing appears.

Who Should Pay the Premium, and Who Shouldn't
Islington Woods is worth it if you need a large home or lot, you want a ravine or premium-lot property specifically, you're buying above about $2.2 million anyway, or a custom build is part of your plan. At those budgets, Sonoma Heights doesn't have what you're looking for.
Sonoma Heights is the better buy if your budget is in the $1.3 million to $1.7 million range, you want a detached family home in western Woodbridge with trail access, and you'd rather put the difference toward a renovation, your savings or a lower mortgage. At that price, an older, smaller home on a standard lot in Islington Woods often costs more and gives you less house than a well-kept Sonoma Heights home.
The in-between buyer, with about $1.7 million to $2 million, has the hardest decision. That budget buys an entry-level home in Islington Woods or one of the best homes in Sonoma Heights. The question to ask yourself is whether you'd rather have the best house on a good street or a good house on a better street. Neither answer is wrong, but you should choose deliberately.

Does Islington Woods hold its value better?
