Gridiron hires union workers from the United Association Local 46, and from other Locals when we have contract projects in other areas of Ontario.

We are a member of the Mechanical Contractors Association of Toronto, making us able to bid on projects exclusive to unionized companies. This designation assures our customers that they are receiving highly skilled labour, and that those employees are protected by their union.

Typically, government organizations (City of Toronto, Ontario tenders, etc.), institutions (schools, hospitals, banks) and large developers hire union companies.
