Cornerstone is the work in progress among the six north-east communities in this series — the one still being built. It sits inside the Stoney Trail ring road on both sides of Country Hills Boulevard, with Skyview Ranch and Redstone to its west and Cityscape to its south (developer; Wikipedia). The 2021 census counted 6,190 residents in 1,795 households; the developer now reports over 4,000 homes built, more than twice that household count, and the community’s own schools, shopping street and parks are arriving in stages.
That “arriving in stages” is the whole story for a buyer. Cornerstone gives you a new house, a new street and neighbours at the same stage of life, at a price that HonestDoor ranks 108th of 306 Calgary communities. What it does not yet give you is a school inside the community — the first public elementary is expected in 2029–2030 — or a train. If you can live with that for a few years, you are buying ahead of the amenities rather than paying for them.
Cornerstone Market Snapshot (2026)
HonestDoor’s September 2026 figures show an average value of $657,440, up 9.2% year over year — the fifth-fastest increase of Calgary’s 306 communities — at about $370 per square foot, with 122 transactions year-to-date (52nd most active). The rental estimate for a typical home is about $2,850 a month. MyCalgary does not yet publish a monthly report for Cornerstone, so there is no community median to quote; ask me for the current MLS® comparables by home type.
Two cautions on that headline growth. HonestDoor’s year-over-year figure compares assessed values, and in a community that is still building, the mix of homes being assessed changes every year — new, larger houses lift the average without any individual house gaining 9%. And CREB®’s August 2026 release describes the North East district as a whole very differently: detached months of supply “above four months in the North and North East districts”, detached “price declines … steepest in the North East at over six per cent”, and row homes in the North East down “over 12 per cent” year over year. Citywide, the benchmark was $569,800 (−1.1% year over year) on 3.92 months of supply (CREB®, August 2026). A buyer in Cornerstone in 2026 is competing with the builders’ own inventory as well as resale listings, which keeps prices honest.
Living in Cornerstone
The 2021 census counted 6,190 people in 1,795 households, an average of 3.4 people per household. It is a young community: 26% of residents are under 15 and only 3% are 65 or older, and 63% of census families have children at home (City of Calgary community profile). Forty-five per cent of homes are single-detached, 22% semi-detached, 13% row and 16% apartments in buildings under five storeys; 83% of households own their home, the highest owner share of the six communities in this series. Median household income was $99,000 in 2020.
Sixty-one per cent of residents are immigrants. Punjabi is the mother tongue of 34% of the community, English of 26%, Tagalog of 6% and Urdu of 5% (2021 census).
The community is master-planned — Walton Development and Management began it and partnered with Anthem United in 2018 (Wikipedia) — with 95 acres of park space and 14 kilometres of pathways planned, wetlands and ponds, seven playgrounds built so far and a shopping street, Highstreet at Cornerstone (developer, liveatcornerstone.ca).
What We Love — and What You Should Know
What we love
- Everything is new. Streets, pathways, ponds and playgrounds built to current standards, and houses under mandatory new-home warranty. Alberta’s New Home Buyer Protection Act requires one year on materials and labour, two years on electrical, plumbing and heating delivery systems, five years on the building envelope and ten years on the structure — and the warranty “is attached to the home, not the owner”, so it carries over to a resale buyer until it expires (alberta.ca).
- Ownership. 83% of households own (2021 census) — the streets are lived in by the people who bought them.
- Highstreet at Cornerstone. A shopping street inside the community rather than a big-box strip on the edge of it (developer).
- Stoney Trail. The ring road is the community’s northern edge; Country Hills Boulevard runs through it to Deerfoot Trail. For anyone driving to the airport, CrossIron Mills, Airdrie or the industrial parks, the location is hard to beat.
What you should know before buying
- The schools are not built yet. The CBE’s Cornerstone Elementary School (K–5, 890 students, 1372 Cornerstone Boulevard NE) received design approval on 14 March 2025 and is expected to open in 2029–2030; a CBE high school for Cornerstone was announced on 15 February 2025 and will be delivered through a provincial public-private partnership bundle (CBE). Until then, children are bused or driven to designated schools in neighbouring communities — check the current designation for the address before you buy.
- No CTrain. The nearest station is Saddletowne. The City’s Blue Line extension in design reaches 88 Avenue NE, a kilometre from Saddletowne; the further extension to Country Hills Boulevard that would serve Cornerstone is in the 10-year capital plan but unfunded (calgary.ca; LiveWire Calgary, 19 August 2026).
- Builder inventory competes with your resale. New homes are still being sold in the community, which caps what a resale can fetch. If you plan to sell within a few years, buy something the builders no longer offer — a finished basement, a larger lot, a corner.
- Growth figures flatter. The 9.2% year-over-year rise in HonestDoor’s average value is a mix effect as much as a price effect; CREB®’s district figures for the North East point the other way.
Schools
Today, Cornerstone’s students attend designated schools outside the community. Under construction or planned inside it: Cornerstone Elementary School (Calgary Board of Education, K–5, capacity 890, expected 2029–2030), a CBE high school (announced February 2025) and, per the developer, a Catholic K–9 school and a public middle school. The Calgary Catholic School District’s nearest new build is its K–6 school in Redstone (estimated opening 2028). Check the CBE and CCSD “find a school” tools for the current designation of any address; designations in this part of the city will change as each school opens.
Getting Around
Cornerstone is a driving community. Country Hills Boulevard runs through it west to Deerfoot Trail and Métis Trail; Stoney Trail forms its northern edge, with the airport, CrossIron Mills and Airdrie a few minutes away and 60 Street NE running south toward Saddle Ridge. Calgary Transit buses connect to Saddletowne station; there is no LRT station in or beside the community, and the Blue Line extension in design stops at 88 Avenue NE (calgary.ca, June 2026 update).
Who Cornerstone Suits (and Who It Doesn’t)
Cornerstone suits buyers who want a new or nearly new home, who drive to work, and who are comfortable that the schools and services will fill in over the next five years — young families especially, given that a quarter of residents are under 15. It suits less well anyone who needs a school in walking distance today, anyone who depends on transit, and buyers who want a settled streetscape with mature trees.
Cornerstone FAQ
How much does a house in Cornerstone cost?
HonestDoor’s September 2026 average value for Cornerstone is $657,440, at about $370 per square foot. MyCalgary does not publish a Cornerstone median yet. Because new and resale homes sell side by side, I quote comparables by home type and builder rather than a single community figure.
Are there schools in Cornerstone?
Not yet. The CBE’s Cornerstone Elementary (K–5) is expected in 2029–2030 and a CBE high school was announced in February 2025; the developer also lists a planned Catholic K–9 and a public middle school. Students are currently designated to schools in neighbouring communities.
Is Cornerstone close to the airport?
Yes — the community sits inside Stoney Trail on Country Hills Boulevard, a few minutes from Airport Trail and YYC by car.
Is Cornerstone a good investment?
The owner share is high (83%) and the rental estimate for a typical home is about $2,850 a month (HonestDoor). The risk is timing: builder inventory competes with resales while the community is still being completed, and CREB®’s 2026 figures for the North East district show soft prices. Buy for the long term and for the home, not for a quick flip.

Where these numbers come from
Market figures on this page are drawn from CREB®’s monthly housing statistics (August 2026, released 1 September 2026) and HonestDoor’s Cornerstone page (September 2026). Population, housing and language figures are from the City of Calgary’s Community Profile for Cornerstone (2021 Census of Canada). School facts are from the Calgary Board of Education’s project pages (Cornerstone Elementary School; “Two New Schools Announced for NE Calgary”, 15 February 2025) and the Calgary Catholic School District; community facts from the developer’s site (liveatcornerstone.ca) and Wikipedia; transit facts from the City of Calgary’s Blue Line LRT extension page (June 2026) and LiveWire Calgary (19 August 2026).
A word on what the numbers mean: the benchmark price is CREB®’s House Price Index figure for a typical home in the area, which is not the same as an average or a median. HonestDoor’s “average value” is an average of assessed values, not sale prices, and in a community still under construction the year-over-year change reflects the changing mix of homes as much as price. Last reviewed September 2026. Market data changes every month; check the source before relying on any figure here, or ask me for current numbers on a specific street or builder.
