Natural Resources Canada (NRCan) has adopted new General Service Lamp (GSL) regulations that will largely harmonize with the current US GSL requirement of 45 lumens per watt minimum.
Timing
Manufactured on or after January 1st, 2026 for general service incandescent lamps or a general service incandescent reflector lamps.
Manufactured on or after January 1st, 2027 for other general service lamps.
For models manufactured prior, refer to the Regulations
Early Compliance: A general service lamp is deemed to satisfy the requirements of sections 4, 5, 435 and 436 if:
- it was manufactured on or after January 1, 2025 and before January 1, 2027 and
- satisfies the requirements of the sections that would have applied to the lamp if it had been manufactured on or after January 1, 2027.
Energy efficiency standard
All general service lamps defined in the Regulations must meet a minimum efficacy of 45 lumens per watt (lm/W) per the energy efficiency standards set out in TSD D7SB001 (PDF, 323 Ko).
Regulatory definition
General service lamp means an electrical device that is used in general lighting applications and that:
- has a base that complies with ANSI C81.61;
- is able to operate, in the case of an integrated lamp, at
- a voltage of 12 V or 24V,
- a voltage ranging from 100 V to 130 V,
- a voltage ranging from 220 V to 240 V, or
- a voltage of 277 V or 347 V;
- is able to operate at any voltage, in the case of a non-integrated lamp; and
- has an initial lumen output of
- at least 310 lm but no more than 3300 lm, or
- in the case of a modified spectrum incandescent lamp, at least 232 lm but no more than 3300 lm.
It includes
- compact fluorescent lamps
- general service incandescent lamps;
- general service incandescent reflector lamps;
- general service light-emitting diode (LED) lamps, and
- general service organic light-emitting diode (OLED) lamps
General service lamps do not include:
- a light fixture;
- an LED downlight retrofit kit;
- an appliance lamp;

- a lamp that has a wedge base or pre-focus base;
- a left-hand thread lamp;
- a marine lamp;
- a marine signal service lamp;
- a mine service lamp;
- an MR-shape lamp that has a first number symbol equal to 16 (diameter equal to 51 mm (2 inches)), as described in ANSI C78.79, operates at 12 V and has a lumen output greater than or equal to 800 lm;
- a fluorescent lamp other than a CFL;
- a plant lamp;
- an R20 short lamp;
- a reflector lamp that
- has a first number symbol less than 16 (diameter less than 51 mm (2 inches)), as described in ANSI C78.79, and
- does not have an E26/E24, E26d, E26/50×39, E26/53×39, E29/28, E29/53×39, E39, E39d, EP39 or EX39 base;
- an S-shape or G-shape lamp that has a first number symbol less than or equal to 12.5 (diameter less than or equal to 40 mm (1.5625 inches)), as described in ANSI C78.79;
- a sign service lamp;
- a silver bowl lamp;
- a showcase lamp;
- a specialty MR lamp;
- a T-shape lamp, other than a CFL, that
- has a first number symbol less than or equal to 8 (diameter less than or equal to 25 mm (1 inch)), as described in ANSI C78.79, and
- has a nominal overall length less than 305 mm (12 inches); or
- a traffic signal lamp.
