Southern Ontario is one of Canada’s most vibrant and economically diverse regions — stretching from lakeside cities to expanding suburban corridors and busy industrial hubs. From the cultural energy of urban centres to the tight-knit feel of smaller towns, businesses here depend on environments that are clean, safe, and ready for daily operations.
Whether it’s a corporate office in the GTA, a manufacturing plant in the southwest, a retail plaza in the Golden Horseshoe, or a community facility in a growing suburban neighbourhood, organizations across Southern Ontario require dependable commercial cleaning services they can trust.
With over 30 years of experience, Jani-King supports the entire region with owner-operated accountability, high cleaning standards, and long-standing local expertise. Our mission is to help Southern Ontario businesses maintain healthy, professional, and welcoming facilities — every single day.
Southern Ontario’s business landscape is incredibly diverse, and so are its cleaning needs. Jani-King builds fully customized commercial cleaning programs that adapt to each facility’s industry, layout, and operational demands.

From daily office cleaning and nightly janitorial care to advanced disinfection and sanitization programs, our teams ensure your workplace remains clean, healthy, and ready for operations.
We offer specialized cleaning for medical and dental offices, retail environments, restaurants, hospitality venues, industrial facilities, warehouses, and multi-unit residential buildings. Our floor care expertise includes everything from strip-and-wax services and carpet extraction to tile, grout, and hard-surface maintenance, helping your floors look professional and last longer.
For facilities that require deeper attention, we provide high-dusting, window cleaning, and thorough deep-cleaning programs, along with reliable post-construction cleanup to prepare newly renovated or built spaces for occupancy. We also manage your facility supplies by restocking essential items like paper products, soap, and sanitizer so your team can focus on operations, not inventory.
