CalgaryNEXT Multisport Fieldhouse Stadium will feature state-of-the-art sports and world-class athletic training facilities. It will be the anchor for a thriving field sport community and with the arena event centre will be the catalyst for new economic growth on the western edge of Calgarys urban core.
Calgarys first Multisport Fieldhouse Stadium will be a multi-functional space, giving Calgarians access to year-round, state-of-the-art field sport and fitness facilities.
The multisport field centre will house a FIFA regulation pitch and a CFL regulation football field in a single configurable space. We will be able to host a major soccer match in the morning and turn over the space for football for Stampeders in the afternoon.
