$4,250,000

Commissioned in 2019 by an award-winning Toronto architect, this seven-thousand-square-foot residence balances brutalist mass with the warmth of white oak and travertine. Floor-to-ceiling glass dissolves the boundary between interior and the half-acre garden beyond. Geothermal heating. Smart-home integration throughout. The kind of home that defines a neighbourhood — and outlasts its time.

05Our Story
Since 1978

A boutique brokerage. By design.

Founded by Theodore Kane in a single Yorkville office, Keystone has grown to forty-eight agents across three Greater Toronto locations — but we have never lost the boutique sensibility that defines us. We turn away more listings than we accept. We answer our phones. We negotiate hard. And we remember that for most of our clients, the home we are listing is the largest asset they own and the most important room they will ever stand in.

01

Discretion

Sixty-seven percent of our luxury transactions never reach public listing. Privacy isn't a feature — it's the baseline.

02

Craft

Every listing is photographed by our in-house architectural photographer. Every floorplan, drafted. Every word, considered.

03

Relationship

Eighty-one percent of our business comes from past clients and their referrals. We're not in the transaction business — we're in the long game.

06For Buyers
For Buyers

A measured approach to buying.

From pre-approval through possession day — our four-stage buyer process, refined over forty years.

01

Consultation

A confidential conversation about lifestyle, budget, neighbourhoods, and architectural preferences. Most clients leave with a five-year plan, not just a wish list.

02

Curation

We hand-select properties — including off-market listings unavailable on MLS. You see five homes worth seeing, not fifty that waste your weekend.

03

Negotiation

Our agents close at 98.4% of asking — by walking away as often as we walk forward. Our job is to win you the home, not the bidding war.

04

Closing

Legal, mortgage, inspection, and possession — coordinated by our concierge team. You sign once, and we handle the orchestra.

07For Sellers
For Sellers

Find out what your home is worth.

A complimentary, no-obligation valuation prepared by a senior partner — typically returned within 48 hours.

No pressure, no obligation. We'll review comparable sales, walk the property if appropriate, and deliver a written market analysis you can hold up to anyone.
