The stadium that learned to breathe and retract
In short: For decades, Vancouver’s BC Place relied on a massive, air-supported inflatable roof. But after a sudden snow-induced tear forced a controlled deflation, the venue underwent a $514 million transformation, replacing a fragile bubble with the world's largest cable-supported retractable roof.
Opened on June 19, 1983, as part of the preparations for Expo 86, BC Place was originally a feat of pneumatic engineering. As the world's largest air-supported domed stadium at the time, it utilized a Teflon Fibreglass roof held aloft by internal air pressure. This design, similar to the Hubert H. Humphrey Metrodome, functioned effectively until a structural crisis in January 2007. During that winter, snow accumulation caused a tear in the ETFE-coated fabric near Gate G, forcing maintenance staff to perform an intentional, controlled deflation to protect the stadium's integrity.
The stadium's evolution reached a turning point following the 2010 Winter Olympics. To modernize the venue, a massive revitalization project was launched, involving a $514 million budget for both phase one upgrades and the new roof construction. The inflatable structure was replaced by a sophisticated retractable system supported by cables, a technology previously utilized by the Commerzbank-Arena in Frankfurt. This new roof, measuring 100 by 85 metres, is the largest of its kind, allowing the venue to transition from an indoor arena to an open-air stadium.
Beyond its structural metamorphosis, the stadium has served as a cultural crossroads. It has hosted everything from the 1986 World's Fair opening ceremonies to a 60,000-person papal address by Pope John Paul II in 1984. Today, the venue maintains its status as a premier global site, having hosted the 2015 FIFA Women's World Cup final and preparing for seven matches during the 2026 FIFA World Cup. Recent years have seen the stadium break attendance records, such as an Ed Sheeran concert in 2023 that drew 65,061 fans, surpassing previous marks set by U2.
