Wow this is confusing i just looked at the Electrical safety regulation and Light fixtures are not included.
When permit is not required for electrical work
18 (1) No permit is required if the only electrical work performed is testing.
(2) An individual may replace the following regulated products without a permit, up to a maximum rating of 150 V to ground, with electrical equipment of a similar type or rating:
(b) cord attachment plugs;
(c) snap switches;
(e) dimmer switches;
(f) fan speed controllers;
(h) overcurrent devices.
(3) An individual may replace, without a permit, a lamp of up to 347 V to ground with a lamp of a similar type or rating.
(4) An individual may replace, without a permit, a fuse of up to 750 V with a fuse of a similar type or rating.
But in the Electrical brochure " A heads Up For Safety" says light fixtures can be changed without a permit up to 150 V to ground.https://www.bconline.gov.bc.ca/news/BCSA_Heads_Up.html
