Construction-site facilities: Canadian requirements

Occupational health and safety requirements depend on the province or territory, the work and whether a federal regime applies. A rented washroom or lunchroom is equipment; the project team remains responsible for the facilities required at the site.

Record the location, maximum number of workers present, shifts, project duration, tasks, accessibility needs and servicing arrangements. Check the applicable rules before work starts and when these conditions change.

The Canada Occupational Health and Safety Regulations, Part IX apply within their federal scope; their fixture tables are not a default for provincially regulated construction. Confirm the governing occupational health and safety regime separately from the building permit jurisdiction.

Select the worksite location below. Each entry identifies the authority and the checks to make before choosing facilities. Where the current fixture table or an amendment has not been verified, the entry states that limit.

Confirm the duties of the employer, constructor, prime contractor, owner and other parties under the legislation applying to the site. Role names and duties differ across Canada. Agree who provides equipment, water, power, cleaning, waste removal, records and replacement units.

The rental agreement should identify included services, response times and exclusions. Before signing, identify the duties that the applicable workplace rules assign to each party, alongside the supplier’s agreed services.

Determine toilet type, numbers, privacy and accessibility under the applicable worksite rules. Requirements can depend on workforce and activity.

What to arrange: State peak headcount, shifts, location, safe access, cleaning, servicing, waste removal and winter operation.

Provide the washing arrangements required for the site and tasks, including suitable water, soap and hygienic drying. Check local running-water and warm-water rules and any exceptions.

What to arrange: Identify water supply, heating, drainage and freeze protection. Assess showers or specialist decontamination for hazardous work.

Arrange potable water appropriate to the work and conditions. Protect drinking supplies from contamination.

What to arrange: Assign supply, storage, replenishment and cleaning. Plan for remote sites, summer heat and freezing conditions.

Assess changing, storage and drying for the workforce and hazards under the applicable occupational health and safety rules.

What to arrange: Allow for winter clothing, wet gear and contaminated protective equipment, with suitable privacy and separate clean storage.

Plan clean areas for meals and breaks with shelter and suitable temperature control. Confirm any specific local requirements.

What to arrange: State simultaneous users, furniture, safe heating, ventilation and cleaning. Keep food separate from contaminated work materials.

This guide does not apply a national toilet-to-worker ratio. Use the applicable construction rules and distinguish flush toilets, chemical toilets, urinals and handwashing facilities. Check the maximum workforce, privacy, accessibility, distance, water supply and maintenance.

British Columbia example: sections 20.3.1–20.3.2 apply to specified construction sites where at least 25 workers will be present at any time during the project. They require sufficient flush toilets unless providing them is not practicable, together with handwashing and maintained facilities. Falling below this threshold does not remove the general workplace washroom duties.

Ontario example: the Construction Projects regulation has its own potable-water, toilet, urinal and clean-up requirements. Determine fixture numbers and servicing records from that regulation and current ministry guidance.

Check the permitted arrangement of separate or individual facilities, locks, lighting and sanitary waste disposal for the workforce. Describe accessibility needs when requesting equipment.

Assess showers and decontamination for the actual substances and tasks. Confirm whether a general washroom trailer is suitable; an ordinary handwashing station does not establish adequacy for hazardous exposure.

For moving work areas, plan safe access and continued availability. Before relying on an existing building, obtain an agreement covering workers, hours, cleaning and supplies, and confirm that the arrangement meets the applicable rules.

Include travel distance, winter access, water delivery, wastewater handling, generator fuel and a replacement plan. Nearby public toilets or a short project duration do not by themselves establish compliance.

Name the person checking cleanliness, water, heat, lighting, supplies and waste levels. Schedule servicing to match actual use and keep cleaning records where required. Protect pipes and tanks from freezing and ensure safe heating and ventilation.

Review the arrangement when workforce, shifts or tasks change. Keep break rooms available and separate food from contaminated clothing and work materials.

Ontario records: since January 1, 2026, Regulation 480/24 provides for a record showing the date and time of the two latest cleanings, posted near the facility or made electronically accessible with directions for workers. Construction-project servicing records under Regulation 213/91 are a separate obligation, covering six months or the project duration if shorter. Keep both requirements in the servicing brief.

British Columbia records: for the specified construction sites covered by section 20.3.2, maintenance, cleaning and sanitizing records must cover at least the most recent 30 days. This period is not a national retention rule.

The tool records the project and provides a specification checklist. It does not determine statutory fixture numbers or certify the site.
