Vaughan Metropolitan Center TorontoThe basics: Part of an extension for Toronto Transit Commission’s York and Toronto subway, the Vaughan Metropolitan Centre Subway Station forms the terminus of the Spadina Subway Extension, one of six new stations on the route. The 143,160-square-foot VMC station, built on undeveloped land in the current commercial district outside of the city, is long and narrow. The station is distinguished by an expansive curved entryway, which acts as a counterpoint to the station’s vertical form and welcomes visitors with a flood of natural light. The curtain wall system for the entrance supports large free spans of glazing to allow daylight to fill the pavilion and allow light transfer to the belowground concourse. The curved perimeter of the entrance complements the transit center’s saddle-shaped roof and is designed to encourage public use.

The glass and systems: Technical Glass Products supplied its SteelBuilt Curtainwall Infinity System, which can use nearly any type of custom steel member as a back mullion. The system’s frame profiles complement the slender back mullions, providing building occupants with narrow sightlines and an open, modern pavilion.

Another project goal was finding a system with enhanced corrosion resistance, given the harsh climate and limited maintenance access. The SteelBuilt Curtainwall Infinity System uses framing members made entirely from a stainless steel alloy.

The main interior elevator shaft, visible through the exterior curtain wall, is TGP’s Fireframes Curtainwall Series.
