A natural gas leak in Innisfil forced the Recreational Complex to close down for a couple hours this morning. The building was evacuated after the smell of natural gas was detected. Customers and staff were moved to safety and The Innisfil town Hall building was made available for people to stay in. The leak was detected on the exterior of the building and Enbridge Gas was in to seal it up. The building was given the all clear to re-open by noon.
