YOW has a second terminal, designed by Richard Brisbin
Ottawa Macdonald–Cartier International Airport, also known as YOW, is located 8 nautical miles (15 km or 9.2 mi) south of downtown Ottawa, Canada. It is the sixth-busiest airport in Canada and the second-busiest in Ontario by airline passenger traffic, serving 4,606,824 passengers in 2024.
YOW covers an expanse of 1,686 hectares (4,166 acres) of total airport property. In 2000, the Ottawa Airport Authority announced plans to build a second, adjacent terminal to accommodate increased traffic. This second terminal was designed by architect Richard Brisbin and was completed ahead of schedule, opening in October 2003. The terminal building handles all airline passenger traffic and features a soothing water feature representing the meeting of the region's three rivers, with copper and limestone finishes that honour the capital's Parliament Buildings.
The original terminal and tower, built in 1960, were designed in a modernist International style by architects James Strutt, William Gilleland, and W.A. of Transport Canada. The new terminal was designed with a focus on creating a calm and easy travel experience for passengers while also celebrating aspects of the region through art. The expansion added 12 gates, seven jetways, and over 7,000 square metres (75,000 square feet) of space.
The architecture and engineering contract for the YOW terminal was awarded to YOW Consultants, an alliance between the Ottawa firm Brisbin Brook Branyon (BBB) and Architecture Planning Interiors Inc. of Vancouver. The terminal's stylised structural components were designed in partnership with GENIVAR, creating an elegant, efficient, and avant-garde roof design. The project was managed by the MRM project management team, a joint venture between Marshall Macklin Monaghan Limited of Toronto and J L Richards and Associates Limited.
