What Hariri Pontarini Architects does

Hariri Pontarini Architects is a 120-person, Toronto-based architectural and urban design practice founded in 1994 by Siamak Hariri and David Pontarini. The firm delivers integrated architecture, interior design, and master planning services across cultural, educational, healthcare, multi-unit residential, mixed-use, commercial, and custom residential typologies for institutional, government, nonprofit, and private developer clients. Its portfolio includes landmark Canadian projects such as SkyTower (106 storeys, Canada's tallest residential tower at Pinnacle One Yonge), The Well (a 3.2 million sq. ft. mixed-use development), OpenROM at the Royal Ontario Museum, the Bahá'í Temple of South America in Santiago, Tom Patterson Theatre for the Stratford Festival, Casey House, the Richard Ivey Building at Western University, and the forthcoming Ontario Science Centre (jointly with Snøhetta).

The firm's core technical differentiators lie in sculptural form-making, material innovation (cast-glass and translucent Portuguese Estremoz marble cladding for the Bahá'í Temple; a bronze veil façade at Tom Patterson Theatre; diagrid glass ceiling and lily pad staircase at OpenROM), and human-centered design for healthcare and cultural environments. HPA pursues sustainability targets such as LEED Gold for the Gibson Art Museum, emphasizes natural light and restorative environments in healthcare projects, and applies specialized structural solutions to supertall residential towers.

HPA generates revenue through professional design fees, project management, and consulting on a project-by-project basis, with custom pricing tied to scope and complexity. Projects are acquired through competitive bids on public commissions, direct relationships with institutional and real estate developer clients, and referrals from prior private clients. The firm is privately held and founder-owned, with no external investment or M&A activity identified, and operates with a senior team that includes partners Doron Meinhard, Lindsay Hochman, and Jeff Strauss alongside the founding principals.

Expansion highlights5 records

Broad incumbents

• Stantec Architecture: Large global design and engineering firm with a substantial Canadian architecture practice spanning healthcare, education, and commercial work. A broader incumbent competing for the same institutional client base as HPA but with vastly greater scale and multi-disciplinary services.

• SOM (Skidmore, Owings & Merrill): Global architecture and engineering firm known for supertall towers, cultural institutions, and mixed-use mega-projects. Competes with HPA for the highest-prestige landmark commissions, including supertall residential like SkyTower-equivalent work.

Emerging players

• Bjarke Ingels Group (BIG): High-profile international design firm with a strong supertall residential and cultural portfolio. An emerging competitor for landmark commissions that could increasingly overlap with HPA's signature work in North America.
