Irrigation & Outdoor Lighting in Ontario

Irrigation and outdoor lighting cover two different trades that often get bundled under one crew because they both involve trenching, low-voltage wiring or piping, and a control system homeowners rarely think about once it's installed. Irrigation work means designing and installing sprinkler systems (zones, heads, backflow preventers, timers), plus seasonal startup and shutdown so pipes don't freeze over a Barrie winter. Outdoor lighting means path lights, uplighting on trees or facades, deck and step lighting, and the transformers and low-voltage wiring that run them. Some of the 7 businesses in this category handle both, others specialize in one.

What to look for before you hire

Ask how zones are planned relative to your lawn's sun exposure and soil type, since a system that waters shade and full sun the same way wastes water and stresses grass. For lighting, ask whether they use low-voltage transformers sized with room to add fixtures later, and whether wiring is buried to code depth rather than just hidden under mulch. Get a clear answer on backflow prevention (most municipalities require it) and whether spring startup and fall winterization are included or billed separately. A contractor who walks your property and asks about problem areas before quoting is usually more reliable than one who prices off a phone call.
