Builders and vendors of new homes in Ontario must be licensed by the Home Construction Regulatory Authority (HCRA) under the New Home Construction Licensing Act, 2017. The initial licence fee is $3,000, with annual renewal at $500 and a Regulatory Oversight Fee of $145 per home enrolled in the Tarion warranty program. First-time applicants must demonstrate competency and pass a Criminal Record Check. All new homes must be enrolled with Tarion Warranty Corporation, which provides statutory warranty coverage. General renovation contractors are not required to hold an HCRA licence, but work involving compulsory trades (electrical, plumbing, HVAC) must be performed by licensed tradespeople. Building permits are required for most structural work.

The general contractor serves as the project manager, coordinating all trades, managing the schedule, pulling permits, and ensuring code compliance. They will provide a detailed contract with scope, timeline, payment schedule, and warranty terms. Progress payments are tied to completed milestones. Expect regular site meetings and communication updates. For new homes, Tarion warranty enrollment and required inspections are part of the process.

Define your project scope, budget, and timeline expectations before meeting contractors. Have architectural or design plans ready if applicable. Research financing options. Get at least three detailed quotes and compare scope, not just price. Check references and visit completed projects if possible. Understand the payment schedule and never pay more than 10-15% as a deposit.

Start planning and getting quotes in late fall or winter for spring construction. Contractors' schedules fill up quickly in spring, so securing a contract 3-6 months in advance is common for major projects.

Watch out for these warning signs: Building new homes without an HCRA licence, which is illegal in Ontario. No detailed written contract specifying scope, timeline, payment schedule, and warranty. Requests more than 10-15% as a deposit before work begins. Cannot provide references or refuses to let you visit completed projects. Does not pull building permits or suggests skipping them to save money. On RealCraft, you can read verified reviews from real customers to help identify trustworthy general constructions.

Before hiring a general construction in Ottawa, ask: Are you licensed with the HCRA (for new home construction) and do you carry full liability insurance? Can you provide a detailed written contract with scope, fixed-price or cost-plus terms, timeline, and warranty? What is your payment schedule, and is it tied to completed milestones? Will you pull all necessary building permits and manage the inspection process? Can I speak with references from your last three completed projects of similar scope?

Yes. A reputable general construction should carry liability insurance and, if they have employees, WSIB (Workplace Safety and Insurance Board) coverage. This protects you from liability if accidents or property damage occur during the work. Always ask for proof of insurance before work begins.
