Light fixture installation in Etobicoke splits neatly in two. Along the lake at Humber Bay Shores and Mimico the ceilings are concrete and the buildings have rules; inland in Alderwood, Long Branch and Islington Village the houses are older, lower and framed in wood.
I handle both. That means swapping chandeliers, pendants, vanity lights and ceiling fans on existing circuits, plus dimmers and smart switches, and knowing which of the two ceilings I am standing under before I start drilling.
