As part of a strategic expansion into the Pacific Northwest and Canada, Perkins+Will merged with Vancouver-based Busby + Associates in 2004 to provide full-service architectural, urban design, interiors and sustainable design consulting. Led by Peter Busby, the Vancouver office is a local and international leader in sustainability and is consistently ranked as one of the Globe and Mail's Top 100 Greenest Companies in Canada. In April 2011, the Vancouver office joined forces with Toronto-based Shore Tilbe Perkins+Will and Dundas- and Ottawa-based Vermeulen Hind Architects to establish Perkins+Will Canada. This three-office merge creates a pan-Canadian practice with four strategic locations and brings an exciting synergy of architectural expertise and talent to the Canadian marketplace as well as the global stage.

With one of the largest portfolios of completed green buildings in Canada and one of North America's leading sustainable practices, the Vancouver office is known for innovative sustainability integrated within a clean, modern vernacular. The office provides expertise spanning various market sectors including corporate, commercial, civic and cultural development along with institutional experience in higher education, K-12 and healthcare. In addition, the majority of Perkins+Will's ground transportation expertise resides in the Vancouver office. With a staff of more than 90 professionals, the office bases design solutions on functionality, durability and value with a view to the life of each building and the well-being of its occupants and users.
