Manufacturing and Warehouse Washroom Compliance Under Ontario's OHSA

Ontario’s manufacturing and warehousing sector has long been subject to some of the most detailed health and safety requirements in the province. The introduction of Bill 190 and O. Reg. 480/24 adds a new documentation obligation that every plant manager, EHS coordinator, and operations director in the sector needs to understand.

This guide covers what Bill 190 requires specifically in manufacturing and warehouse environments, how the regulation interacts with the existing requirements under Ontario Regulation 851 (Industrial Establishments), and the practical steps for getting — and staying — compliant.

The Existing Framework: Ontario Regulation 851

Before getting into Bill 190 specifics, it’s worth noting that manufacturers and warehouse operators already operate under an existing washroom standard under O. Reg. 851, Ontario’s Industrial Establishments regulation.

O. Reg. 851 has long required that sanitary facilities provided to workers in industrial workplaces be kept clean and in good repair. It sets minimum standards for the number of toilets required relative to workforce size, requires adequate lighting and ventilation in washrooms, and mandates that facilities be kept sanitary.

The “kept clean” standard in O. Reg. 851 has always existed. What Bill 190 and O. Reg. 480/24 add is an accountability layer: now, employers must not only maintain clean washrooms — they must document the cleanings and make those records accessible to workers.

In practical terms, Bill 190 doesn’t change what manufacturers need to do in their washrooms. It changes what they need to document and show.

What Bill 190 Requires in Manufacturing and Warehouse Settings

Under O. Reg. 480/24, effective January 1, 2026, Ontario manufacturers and warehouse operators must:

1. Keep a cleaning record for every washroom facility

This means every washroom your workers use — production floor washrooms, warehouse washrooms, office washrooms, locker room washrooms, and any other facility you provide for employees. Each washroom needs its own individual record.

2. Ensure the record shows the two most recent cleanings

The record must include the date and time of each of the two most recent cleanings for that washroom. Not just the date — the time as well.

3. Make the record readily accessible to workers

The record must be posted in a conspicuous place in or near the washroom, or made available electronically with clear instructions on how workers can access it. Workers must be able to view the record without asking a supervisor or manager.

4. Keep the record current

The record should reflect actual cleaning activity. A log that shows cleanings only every third day when your facility cleans daily is not a compliant record — it’s an incomplete one.

Specific Considerations for Manufacturing Environments

Manufacturing environments have some characteristics that affect how washroom compliance works in practice. Here’s what plant managers should think through:

High-traffic washrooms and cleaning frequency

In a facility with multiple production shifts, washrooms may be in heavy use for 16 or 24 hours a day. Cleaning frequency in these environments is often higher than in an office setting — sometimes every two to four hours on busy shifts. Your cleaning log needs to reflect this reality.

A log that shows one cleaning per day in a 24/7 production facility doesn’t look credible to an inspector. Make sure your cleaning schedule aligns with your actual washroom usage, and that your logging captures every cleaning — not just one summary entry per shift.

Shift changes and cleaning staff handoffs

Manufacturing operations often involve multiple cleaning staff across multiple shifts. Ensure that every person responsible for washroom cleaning in your facility understands the logging requirement — it’s not just the day shift’s job. If the night shift cleans the washroom at 2 AM, that cleaning needs to be in the record.

This is an area where digital QR-based systems significantly outperform paper. A night-shift cleaner scanning a QR code creates an automatic, timestamped record of that cleaning without any paper to transfer or transcribe.

Multiple washrooms across a large floor plan

A large manufacturing facility may have washrooms at multiple points on the production floor, in warehouse areas, in the office wing, and in locker room areas. Each of these is a separate washroom facility requiring its own cleaning record.

For facility managers, the practical question is: how do you efficiently confirm that all of these records are being maintained without physically visiting each washroom every day? A digital cleaning log system with a centralized dashboard solves this problem — you can see at a glance which washrooms have been logged and which haven’t, from any device.

Contract and temporary workers

Manufacturing and warehousing operations often use contract workers and temporary agency workers, particularly during peak production periods. These workers are protected by OHSA in the same way as direct employees, and the washroom records must be accessible to them as well.

If you’re using a QR-based system, this is automatic — any worker can scan the QR code to see the record. If you’re using an electronic system that requires login credentials, ensure that temporary workers either have access or that you’ve posted sufficient physical instructions that they can access the records without a login.

Visitors and contractor workers on-site

Workers from other companies who are present at your facility for work purposes — trades contractors, service technicians, delivery workers on extended assignments — are also workers under OHSA while in your workplace. The washroom compliance obligation extends to them.

Outdoor and remote facilities

Some manufacturing and warehouse operations have washroom facilities that are physically separated from the main building — portable units for seasonal workers, external facilities for receiving and shipping areas, or facilities in detached warehouse buildings. The compliance obligation applies to all washroom facilities provided to workers, regardless of location.

How Bill 190 Fits Into Your Existing EHS Program

For most manufacturers, Bill 190 washroom compliance should be integrated into your existing health and safety management system rather than treated as a standalone initiative.

If you have a Joint Health and Safety Committee (JHSC), washroom compliance should be on the agenda. The JHSC is a natural forum to confirm that cleaning records are being maintained, to surface any worker concerns about washroom conditions, and to review the compliance approach on a periodic basis.

If your facility is subject to external audits — customer audits, ISO certification, or third-party EHS assessments — your auditors may start asking about Bill 190 compliance documentation as part of their assessment process. Having a clear, documented compliance program makes this straightforward.

A Note on the Inspection Reality in Manufacturing

The Ministry of Labour inspects manufacturing and industrial workplaces regularly — this sector is a consistent priority for OHSA enforcement. Washroom compliance is now part of the standard inspection checklist.

Inspectors visiting your facility for any reason — an incident investigation, a worker complaint, or a proactive sector inspection — can and will assess washroom compliance. The condition of the records, their accessibility to workers, and the credibility of the cleaning frequency documented are all things an experienced inspector will evaluate quickly.

The most common compliance gaps inspectors find in manufacturing settings are:

• Records that exist on paper but aren’t being filled in after each cleaning

• Records that are accessible to management but not to workers on the production floor

• A single centralized record covering multiple washrooms rather than individual records per facility

• Cleanings being logged at the end of a shift in one batch rather than in real time

Each of these gaps is straightforward to close with the right system and staff training.

Getting Started: A Practical Checklist for Ontario Manufacturers

If your facility hasn’t yet addressed Bill 190 washroom compliance, work through this checklist:

☐ Inventory all washroom facilities in your workplace, including production floor, office, warehouse, locker room, and any external or remote facilities

☐ Count each washroom separately — one record is needed per washroom facility

☐ Assess your current cleaning documentation — is anything being recorded? In what format?

☐ Choose your compliance system — paper logs posted in each washroom, or a digital QR-based system

☐ Set up and install records in each washroom — paper logs mounted visibly, or QR codes mounted at eye level

☐ Train all cleaning staff — every person who cleans a washroom needs to know how to log the cleaning

☐ Train supervisors on what to do if records are found to be incomplete

☐ Include cleaning log requirements in onboarding for new cleaning staff and temporary workers

☐ Set a monitoring cadence — how often will supervisors or EHS staff confirm records are being maintained?

☐ Integrate compliance review into JHSC meetings

For a manufacturing facility with multiple washrooms and multiple shifts, a digital system is almost always the better choice — the management overhead of maintaining paper compliance at scale is substantial, and the audit trail from a digital system is far more defensible during an inspection.
