Road flaggers for your work sites and events
Certified flaggers who control traffic and protect your workers and road users, in the Quebec City area, in Montreal and elsewhere in Quebec depending on your project.

Safe traffic control, from the first cone to the last vehicle
During road construction or maintenance work, well-executed human signalling makes all the difference. McKinnon road flaggers direct traffic to keep site workers, drivers, cyclists and pedestrians safe.
Whether traffic needs to be stopped, run in alternating directions or warned of a work area that is hard to see, our teams adapt to your site layout and schedule, from a one-time job to a long-term contract.
Our flaggers handle
- Alternating one-lane traffic
- Full or partial street closures
- Reversing manoeuvres of heavy vehicles on work sites
- Work site entrances and exits
- Events, festivals and gatherings
- Emergency work and short jobs

Frequently asked questions
Are your flaggers certified?
Yes. Our road flaggers are AQTR-certified and wear the required protective equipment, including CSA Z96 high-visibility clothing.
How many flaggers does my site need?
It depends on the site layout, the type of closure and the road speed. Describe your project and we will advise you. In any zone above 70 km/h, the TCD-005B standard (alternating traffic with a flagger barrier) is required.
Can you respond quickly?
Yes. Our teams are available 24/7 and handle planned projects as well as urgent needs.
Do you also provide signage and plans?
Yes. McKinnon offers a turnkey service: signage rental and installation, signed and sealed traffic control plans, and flaggers on site.
