Ironworkers Local 721's site is provided for the education of our members and the greater community on the benefits and opportunities associated with membership in our organization. Our Local is over 3200 members strong and growing. Together we've erected some of the most prominent and well known buildings in this city. The CN Tower, Rogers Centre (Skydome), and Toronto City Hall are just a few that make up Toronto's skyline. We're proud to represent such a great city and such great members. Local 721 is committed to providing the highest in quality, safety and reliability, and our projects reflect that attitude.
