Thinking about renovating your kitchen, bathroom, or basement? Before you hire anyone, there are a few things you should know — because in Ontario, anyone can call themselves a contractor.
There's no provincial license for general contractors. So what should you actually be looking for?
✅ General Liability Insurance — protects your home and property if something goes wrong on the job
✅ WSIB Clearance Certificate — covers workers on your site. No WSIB? You could be personally liable if someone gets hurt.
✅ Licensed tradespeople for the right work — electrical, plumbing, and gas work must be done by certified, ticketed trades who pull the proper permits. No permits = failed inspections, voided home insurance, and headaches at resale.
✅ A written contract — a professional stands behind their work in writing.
Anyone who hesitates to provide these things is waving a red flag for you.
At Warren & Co, we carry full liability insurance, maintain our WSIB, work with certified tradespeople, and always do things right — because your home is worth it.
