Built on 25 Years of Showing Up
A Thornhill-based general maintenance and staffing company with deep roots in Ontario — and an uncompromising commitment to reliability.
A Full-Service Maintenance & Labour Provider
3C Group is an Ontario-based general maintenance and staffing company with over 25 years of experience serving commercial, industrial, and multi-residential clients. We started with a simple commitment: provide trained, dependable workers who treat every job site like their own.
Today, we deliver a full range of services — from professional cleaning and general labour to seasonal exterior maintenance and general contracting — backed by a team that takes quality seriously.
Client-Focused. Flexible. Local.
We're not just a staffing agency — we're a service partner that shows up, stays accountable, and delivers results that speak for themselves.
Client-Focused
Every decision starts with our clients. We listen, adapt to your schedule, and measure success by your satisfaction — not ours.
Flexible Service
One call mobilizes one worker or an entire crew. Short-term, long-term, or emergency — we flex to your requirements without compromising quality.
Local Ontario Expertise
Based in Thornhill, we know Ontario's regulations and communities inside out. Local roots mean faster response and better accountability.
25 Years of Results
Four Core Service Areas
From daily cleaning routines to complex construction projects, we bring the right people with the right skills to every job. Our four service categories cover virtually every maintenance need a property manager could have.
Long-term contracts or urgent one-offs — our team is structured to handle both with the same level of professionalism and care.
