At CSS, safety is the foundation of everything we do. Every one of our Traffic Technicians undergoes intensive training before ever stepping onto the road. This includes Book 7, POST, First Aid, 4 & 5 Steps, and Flagger certification — ensuring they are fully prepared to manage complex and dynamic job sites with confidence and precision. Our team brings a proactive, detail-oriented approach to every project to protect workers, motorists, and the public alike.

We offer a full range of services including seamless road permit coordination across the Greater Toronto Area, digitally detailed work zone layouts, full lane and road closures, pedestrian and work zone protection, and more. We are ISN Verified and certified through Avetta and Highwire, upholding high standards in compliance and safety.

At Construction Support Services, we manage the complex details — so you can work with confidence, knowing it’s all handled. As one of Toronto’s leading and cost-effective traffic management companies, we know that no two projects are the same. That’s why we offer tailored, end-to-end solutions designed to support your team from start to finish.

From handling road permit applications and digitally detailed work zone layouts, to overseeing on-site safety and ensuring every crew member and piece of equipment is cleared properly — we manage the details so you don’t have to. Whether you’re dealing with a full roadway closure or a high-traffic urban intersection, CSS is your trusted partner for safe, efficient, and hassle-free execution.
