About Supreme Cleaning Group
Supreme Cleaning Group is a commercial cleaning company headquartered in Markham, Ontario, cleaning offices, medical and dental clinics, daycares, restaurants, warehouses, and condo buildings across the Greater Toronto Area. Below you will find who we are, how we work, and what you can hold us to.
Supreme Cleaning Group Inc. is a Markham-based commercial cleaning and janitorial company that has been operating in Ontario since 1999. Our head office is at 22-570 Hood Road in Markham, and our crews work out of it every day across the Greater Toronto Area and the wider Ontario market.
We are a specialist commercial cleaner rather than a general cleaning service. Most of our work is recurring contract cleaning for businesses that cannot afford an inconsistent result: medical and dental practices, daycare centres, restaurant kitchens, warehouses, professional offices and multi-unit condo buildings. We also handle project work such as post-renovation cleaning, move-in and move-out cleaning, and real estate cleaning for agents preparing a property to list.
What that means for you in practice is three things. You get a team that already knows the standard your type of space is held to. You get the same crew on your site wherever scheduling allows, so nobody has to be retrained on your building every visit. And you get one phone number, 833-866-6161, for quotes, scheduling, and anything that goes wrong.
If you are comparing cleaning companies right now, the rest of this page is written to be checked rather than skimmed. Where we make a claim, we have tried to attach a name, a number or a mechanism to it.
Supreme Cleaning Group started in 1999 as a small commercial cleaning crew servicing offices in Markham, Ontario.
We started the company after seeing a need for more reliable, consistent, and customer-focused service in the industry. With firsthand experience in the field, we wanted to build a company where quality work, dependable service, and lasting customer relationships were treated as priorities from the beginning.
Over the past 25-plus years, that crew has grown into a team of vetted cleaning professionals serving commercial and residential clients across the Greater Toronto Area and Ontario. The work has broadened from general office cleaning into the regulated and higher-risk spaces we handle most often today, including medical office cleaning, dental practices and licensed daycare centres.
Two things have not changed. We are still Markham-based and Ontario-owned, working out of the same Hood Road office. And we are still structured as a direct-employer cleaning company rather than a franchise network or a national contractor with a local sales desk. When you call, you reach the company that does the cleaning.
We built the Supreme Cleaning Group around a simple idea: a clean space is a healthier, safer, and more productive one. That shows up in three commitments we hold ourselves to on every job.
We use hospital-grade disinfectants and cleaning protocols on every medical and dental office we service, not only when a client asks for it. Touchpoint disinfection, colour-coded cloth systems to prevent cross-contamination between zones, and washroom protocols built for clinical settings are standard, not an upgrade.
We use environmentally responsible cleaning products across our residential and commercial work, because the people using the space matter as much as the space itself. This matters most in daycares and clinics, where occupants are in the building for long stretches and residue and fumes are a genuine concern.
Where scheduling allows, we assign the same cleaning team to a client’s site regularly, so the people cleaning your space know it. They know which meeting room gets used hardest, which floor finish cannot take a wet mop, and which door needs the code.
Supreme Cleaning Group covers 17 distinct service lines. The ones below account for most of our contract work across Ontario.

If your site sits outside these cities, call 833-866-6161 and we will tell you honestly whether we can service it properly.
Plenty of cleaning companies serve Markham and the Greater Toronto Area. Here is where we differ, in terms you can verify before you sign anything.
Medical offices, dental practices and licensed daycares are held to hygiene standards that a general office cleaner is not trained for. Hospital-grade disinfection is our default for those sites, not an add-on line item.
We are not a franchise network or a national contractor with a local sales office. Our head office is at 22-570 Hood Road in Markham, and one number, 833-866-6161, reaches scheduling, quoting and support.
Wherever scheduling allows, your site keeps the same team. That is the single biggest predictor of whether quality holds up in month eight of a contract.
Office cleaning, medical and dental, daycare, restaurant, warehouse, condo, janitorial, post-renovation, carpet and move out work are all handled in-house, so you are not managing four vendors and four invoices.
Not a premium tier. Standard.
Since 1999.
