Electrical, gas and plumbing are licensed trades almost everywhere (for example ESA for electrical and TSSA for gas in Ontario), so check your provincial regulator that the contractor is certified for the work before you hire. - A construction lien is a real risk: in every province an unpaid subcontractor or supplier can register a lien against your home even if you already paid the main contractor. Hold back the statutory amount (commonly around 10%) and get signed lien waivers as you pay. - Ask to see a portfolio of completed work like yours, plus recent references you can contact. - Check the credentials and registrations that matter for this work, and that they are current. - Get a written, itemised quote with scope, assumptions and a staged payment schedule. --- Source: MyTrustedTraders, https://ca.mytrustedtraders.com/traders/one-one-construction-services-inc Real public evidence only: every figure traces to a named source and is cross-checked.
