Thornhill straddles the Vaughan-Markham boundary, and it's one of those neighbourhoods where you'll find a 1960s bungalow next door to a large custom rebuild — which means the electrical needs on any given street can vary a lot. We're used to working around that: matching a full panel upgrade to a heritage-style home, or wiring a modern lighting package into a newer custom build, without treating either job like a template.
