What to check when hiring drainage contractors in Ottawa

MyTrustedTraders ranks on independent public evidence. No ads, no paid placement. Use these checks alongside the evidence on each profile before you decide who to contact.

  • Trade licensing in Canada is set by each province or territory. 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.
  • Confirm they cover your area and can actually come out in your timeframe before anything else.
  • Read recent reviews for reliability and turning up on time, not only the quality of the work.
  • Agree the call-out fee up front, and be wary of large upfront deposits for an emergency job.
