Professional washroom cleaning for Markham businesses — with signed cleaning logs for Bill 190 (OHSA s.25.3) compliance. Serving Highway 7, Markham Centre, Enterprise Park, and all Markham business districts.
Markham is home to one of the most concentrated commercial corridors in the Greater Toronto Area. The Highway 7 corridor alone spans dozens of medical offices, tech companies, restaurants, and retail plazas between Warden Avenue and the 404. Markham Centre, the city's emerging downtown core, adds hundreds of office tenants, ground-floor retailers, and food service businesses. Enterprise Business Park and Milliken Mills serve light industrial and logistics operations. Every employer in every one of these areas — regardless of size or industry — is now subject to Ontario's washroom cleaning record requirement under Bill 190.
Since OHSA s.25.3 came into force on July 1, 2025, Markham businesses must maintain documented records of when their workplace washrooms were last cleaned. The records must be accessible to a Ministry of Labour inspector at any time. The law applies to a 3-person accounting office in a Markham Centre tower and a 300-person warehouse in Milliken Mills equally.
Every Ontario employer must keep records of when each workplace washroom was last cleaned and make those records available for inspection. Records may be kept digitally or on paper (OHSA s.1(5), in force October 28, 2024). Failure to maintain records is an offence under the Act. Read the full Bill 190 breakdown →
The most common challenge we hear from Markham businesses isn't the cleaning itself — it's the documentation. Staff washroom cleaning happens informally, on an ad hoc basis, with no written record. That practice no longer satisfies the legal requirement. A professional washroom cleaning contract solves the problem completely: we clean on a fixed schedule, sign a dated log at every visit, and give you a copy. If an inspector walks in tomorrow, your records are current and organized.
Zusashi Maintenance has been serving Markham commercial clients for over 18 years. Our washroom cleaning teams know the city's business districts — from the medical offices clustered near Markham Stouffville Hospital and the tech campuses along the 404 corridor, to the dense retail plazas on Steeles Avenue East and the office towers taking shape in Markham Centre. We offer standalone washroom cleaning contracts with no requirement to take on full office cleaning, and month-to-month terms with no lock-in.
Washroom cleaning and Bill 190 compliance coverage across every major Markham commercial and industrial area
Markham's primary commercial spine from Warden Avenue to McCowan Road. Dense with medical offices, dental clinics, restaurants, retail plazas, and professional services. High foot traffic means washrooms need daily service and consistent documentation for compliance inspections.
The city's growing urban core around Enterprise Boulevard and Main Street Unionville. Multi-tenant office towers, ground-floor retail, and food service operations. Many tenants manage their own interiors but need documented washroom service to satisfy OHSA s.25.3 obligations independently.
Major industrial and office park in the Warden/Steeles area. Home to logistics operations, light manufacturing, and technology campuses. Warehouse and industrial facility washrooms often serve shift workers around the clock — frequency and documentation need to match actual usage patterns.
The 16th Avenue and Highway 7 zone along the 404 houses IBM Canada, AMD, and numerous technology companies in purpose-built campuses. These facilities have high employee counts and institutional-grade expectations for hygiene standards and compliance documentation.
Concentrated industrial and commercial area along Steeles Avenue East toward Scarborough. Warehouses, light industrial units, and office-warehouse hybrids. Ministry of Labour inspections are routine in this corridor — washroom records need to be consistently maintained and readily accessible.
Medical offices, specialist clinics, physiotherapy practices, and dental offices clustered along the 9th Line and Bur Oak Avenue corridor. Healthcare facilities already operate under strict hygiene protocols — OHSA s.25.3 adds a formal documentation requirement on top of existing standards.
Full-service cleaning plus a signed Bill 190-compliant log after every visit
Every sector in Markham's commercial landscape has the same Bill 190 obligation — here's how it plays out in practice
Markham's tech campuses typically house 100–500+ employees. With multiple washrooms per floor and high daily usage, consistent documented cleaning is both a compliance need and a workplace health expectation from employees.
Clinics and dental practices already follow IPAC protocols. OHSA s.25.3 adds a formal record-keeping layer. Patient-facing washrooms in healthcare settings are particularly scrutinized during MOL inspections.
Markham's Hwy 7 strip plazas and Markham Centre retail units face steady consumer foot traffic. Public washrooms in retail settings need documented cleaning that satisfies both Bill 190 and public health expectations.
Food service operators in Markham already manage DineSafe inspections. Washroom records under Bill 190 add another documentation layer — best handled through a professional service that manages the paperwork automatically.
Enterprise Business Park and Milliken Mills warehouses often have shift-based workforces and multiple washroom blocks. MOL inspectors are routine visitors in industrial settings — records need to be consistently maintained.
Fitness facilities in Markham face high washroom usage across morning, lunch, and evening peaks. Daily — and sometimes twice-daily — cleaning with documentation is the standard for compliance in this sector.
Markham's commercial density means many businesses already have cleaning arrangements in place — a janitorial service for common areas, in-house staff for general tidying, or a property management company handling shared spaces. What those arrangements rarely produce is a dated, signed record of each washroom cleaning that satisfies the specific language of OHSA s.25.3.
A standalone washroom cleaning contract fills exactly that gap. We don't disrupt what's already working in your facility. We arrive on the agreed schedule, clean the washrooms to a documented standard, leave a signed log at the location and send you a digital copy. Your other cleaning arrangements stay in place. The compliance piece — the one that Ministry of Labour inspectors will ask for — is fully covered.
This structure is particularly common among Markham's smaller professional offices: accounting firms, law practices, engineering consultancies, and financial services companies that operate lean and clean their own spaces but recognize that informal washroom cleaning isn't adequate documentation under the new law. It's also increasingly popular with property managers in multi-tenant buildings who want to handle washroom compliance at the building level, independent of individual tenant cleaning contracts.
Our Markham washroom cleaning teams are assigned on a consistent basis — the same staff, the same schedule, every week. You're not getting a different crew from a staffing pool with no continuity. Consistency matters both for cleaning quality and for the integrity of the compliance record you're building over time.

Yes. Standalone washroom cleaning is available across all Markham business areas. This is our fastest-growing service since Bill 190 came into force on July 1, 2025 — many Markham businesses already manage their own general cleaning but lack documented washroom records.
