CMEQ's 2026 amendments — what actually changed for residential.

Every three years the CSA publishes a revised Canadian Electrical Code. Quebec adopts it through the CMEQ with provincial amendments — usually 12–18 months later. The 2024 cycle went live for us on October 1st. Here's what's actually different on a residential job.

AFCI on (almost) every circuit

Arc-Fault Circuit Interrupters used to be required on bedroom receptacle circuits only. Under the 2026 amendments, AFCI protection is now required on virtually every 120V branch circuit in a dwelling unit. The exceptions are short and worth knowing:

• Bathroom receptacles — GFCI is required instead.
• Garage and outdoor receptacles — GFCI suffices.
• Dedicated appliance circuits (range, dryer, water heater) — neither required.
• Lighting-only circuits — still AFCI required as of 2026.

For new construction this means most panels are now stacked with AFCI breakers — significantly more expensive than standard. For renovation work touching an existing branch circuit, the new circuit needs AFCI even if the rest of the panel doesn't.

Bathrooms · dedicated circuit by default

Old rule: bathroom receptacles had to be GFCI, but could share a circuit with other rooms. New rule: each bathroom needs its own dedicated 20A circuit, GFCI-protected, with no other outlets on that circuit.

This catches every renovation that touches a bathroom. Even swapping a vanity that requires moving a receptacle now triggers the rule. The pragmatic answer: pull a new home-run during the reno, even when you don't have to. It future-proofs and removes the inspector argument.

Outdoor receptacles · “in-use” covers

Outdoor receptacles already required weatherproof “while-in-use” covers for years. The 2026 rule tightens it: all outdoor receptacles, including those installed under eaves and in semi-protected locations like covered porches, need the dome-style cover that's rated “extra-duty in-use”. The basic flap cover doesn't qualify.

For new builds this is a $30 line item. For retrofit, it's pulling old covers off existing receptacles — we do this as a courtesy on any outdoor work because it's a 90-second job and an inspector flag.

EV chargers · two new touch points

• Energy management systems now have explicit code recognition. Chargers with built-in EMS (Wallbox, FLO, Tesla Wall Connector) can derate dynamically and the panel can be sized to lower-than-nameplate values — provided the install is documented.
• Outdoor charger receptacles need GFCI even if the charger itself has internal protection. Belt-and-suspenders.

Grandfathering · what stays legal

Existing installations done under earlier code remain compliant under the rule that was current when they were installed. You don't need to rip out a 2018 bedroom-only AFCI setup to comply with 2026. But — and this is the gotcha — the moment you touch that circuit for renovation work, the new rules apply to the modified portion.

Most homeowners don't realise that “just moving an outlet” can trigger an AFCI breaker upgrade. We always explain this before scoping a reno quote.

What to do as a homeowner

1. If you're starting a renovation, ask your electrician to walk you through the 2026 deltas that apply to your scope. There should be no surprises at inspection.
2. If you're getting an EV charger and your panel is full, ask if the new charger's EMS lets you avoid an upgrade.
3. If you have outdoor receptacles with flat flap covers, swap them. Cheap, fast, makes future inspections easier.
4. If your electrician quotes a job without mentioning AFCI for a new circuit, get a second quote.
