“Irshad and his team installed potlights throughout our main floor, hooked up our new appliances and added under-cabinet lighting in the kitchen. Clean, precise work and the ceiling patch lines are invisible. Everything was left spotless at the end of each day.”
The Electrical Side Nobody Talks About
Search for universal washroom installers and you'll find door companies, locksmiths and accessibility consultants. Almost none of them mention that the heart of the system — the electric strike and magnetic lock that releases the door, the power supply feeding the operator, and the emergency call system — is line-voltage and low-voltage electrical work that legally requires a licensed electrical contractor. Door companies mount the operator and then call an electrician anyway; you pay for the coordination, and if something fails, each trade points at the other.
We hold the electrical licence, so we own the whole system: power supply and circuit, electric strike or lock integration with the fire alarm, push-button and occupancy-indicator wiring, and the emergency call station with its remote light and optional sounder. One contractor, one warranty, one accountable phone number — and an ESA connection record that satisfies your inspector and your insurer.
OBC 3.8 & AODA: What the Code Actually Requires
Ontario's accessibility requirements for washrooms come from two directions: the Ontario Building Code, Section 3.8 (barrier-free design), and the AODA, whose Design of Public Spaces and IASR standards push existing buildings toward the same targets during renovations. The dimensions that matter in practice:
| Requirement | OBC 3.8 specification |
|---|---|
| Washroom door clear width | 860 mm minimum |
| Turning space | 1,500 mm diameter clear turning circle |
| Water closet seat height | 430 – 485 mm above floor |
| Grab bars | L-shaped and horizontal bars at prescribed heights/positions beside and behind the toilet |
| Clear floor space | Minimum clear manoeuvring space at fixtures (commonly a 1,700 mm × 2,200 mm room footprint) |
| Controls (faucets, flush, dispensers) | Operable with one hand, without tight grasping or twisting |
Doors in these rooms are typically held closed with an electric strike so they can be unlocked automatically from the push-button, the emergency call system or the fire alarm — which is exactly where the electrical work begins. We coordinate with your contractor or designer so the electrical rough-in lands before the finishes go in, not after.
O. Reg. 368/13: Emergency Call Systems Are Mandatory
Since January 1, 2015, Ontario's Integrated Accessibility Standards (O. Reg. 368/13) require an emergency call system in every universal washroom in buildings governed by the regulation — a two-part system with a call station inside the room (reachable from the toilet and the floor, usually a pull cord with two actuation levels) and a visual indicator (light) and optional audible signal outside the door. This isn't a recommendation and it isn't a nice-to-have: inspectors flag missing or non-functional call systems routinely, and retrofitting one into a finished washroom costs far more than roughing it in during construction.
Because the call system is wired electrical equipment, its installation belongs with your electrician — not your millworker. We install call stations, remote indicators and sounders, integrate them with the door release so help can enter, and test the full sequence: pull the cord, the light goes on outside, the door can be released, the signal resets properly at the station. That's the compliance sequence an inspector will actually test.
What's in a Universal Washroom Package
One honest note on terminology first: you'll hear "barrier-free," "accessible" and "universal" washrooms used interchangeably in Ontario. Barrier-free design is the OBC 3.8 framework; "universal washroom" is the regulated term for the single-user room at the centre of the AODA requirements — including the mandatory emergency call system. Whatever you call it, the electrical scope is the same, and it's ours.
A code-compliant, fully functional universal washroom combines several components into one system:
- Door operator — a low-energy swing operator that opens the door at the touch of a button, sized to the door's weight and traffic.
- Push buttons — interior and exterior wall-mounted or wireless buttons; we wire hardwired units on their own low-voltage circuit.
- Electric strike or magnetic lock — releases the latch so the operator can swing the door; wired and integrated with the fire alarm so the door unlocks on alarm, as the code requires.
- Emergency call kit — pull-cord station, exterior light and optional sounder, wired and tested end to end.
- Occupancy indicator — the sliding "occupied/vacant" sign integrated with the lock, so staff can see at a glance whether the room is in use — and whether the call light is on.
Each component is simple on its own; the compliance lives in how they're wired together. That's the part we do that hardware sellers can't.
Retrofit vs. New Construction
New construction and full renovations are the easy case: we rough in power and low-voltage wiring before drywall, coordinate door hardware with the door supplier, and commission everything before occupancy inspection. Roughing in during construction typically saves 30–50% versus retrofitting the same system later.
Retrofits — an existing restaurant, office or place of worship adding a universal washroom or upgrading to meet current standards — are most of our GTA work. They take more ingenuity: power must be pulled to the door frame cleanly, low-voltage runs routed through finished ceilings, and the fire-alarm tie-in coordinated with your existing panel. We assess the site, give you a fixed quote, and schedule work around your operating hours so washrooms are back in service fast.
Who Needs a Universal Washroom — and How Many
The "one universal washroom per three floors" rule catches building owners off guard: multi-storey buildings without a barrier-free washroom on every floor group must provide one universal washroom for every three storeys, located so occupants don't have to travel past that span to reach it. Additions, major renovations and change-of-use permits commonly trigger the requirement for existing buildings. In practice, we install these systems for:
- Restaurants and food service — where a single washroom must serve everyone, and a universal design removes the accommodation scramble.
- Offices and medical clinics — staff and patient needs under AODA obligations.
- Malls and retail plazas — landlord standards plus public-space standards.
- Schools and community facilities — high-traffic, high-scrutiny environments.
- Places of worship and banquet halls — often older buildings doing thoughtful retrofits.

What Inspectors Actually Check
Whether it's a building inspector at occupancy, a fire inspector reviewing your alarm tie-ins, or an accessibility audit, the failures we see flagged in GTA buildings are remarkably consistent: emergency call cords tied up out of reach (they must reach the floor), call systems with no exterior indicator, doors that unlock on alarm but can't be opened against the operator's spring pressure, push buttons mounted at the wrong height or on the wrong side of the door, and occupancy indicators wired backwards. Every one of those is a wiring or commissioning issue — not a plumbing or millwork issue. Our commissioning checklist tests each item the way an inspector will, so the visit ends with signatures, not orders.
Beyond the Door: The Full Accessibility Picture
The door controls are the electrical piece of a larger room, and the rooms that work best are the ones planned as a system: the electrician roughs in while the walls are open, the plumber sets fixtures at compliant heights, the door supplier hangs a door the operator can actually handle, and someone — ideally us, since the call system and the door release are ours — confirms the whole sequence works before inspection. If your project includes a broader renovation, our office renovation electrical and restaurant electrical services cover the fit-out around the washroom as well, with one contractor holding the schedule.
