## How do you choose a general contractor in Markham?

To choose a Markham general contractor, check its WSIB clearance and liability cover, ask who pulls each permit, then compare written quotes. Ontario law says any home reno contract worth more than $50 must be in writing. The province also suggests a deposit of no more than 10% of the price.

1. **Check the licence.** A general contractor hires the trades, and Ontario says no one can run an electrical contracting business without an ESA licence. Check the electrician on your job in [ESA's Contractor Locator](https://licensing.esasafe.com/contractor-locator-tool/).
2. **Confirm WSIB clearance.** Ask for the company’s WSIB account number and confirm a current clearance on [WSIB’s free eClearance lookup](https://clearances.wsib.ca/Clearances/eclearance/start?lang=en).
3. **Ask for proof of liability insurance.** A certificate of commercial general liability insurance should name the company that will do the work.
4. **Ask about city licences and permits.** Ask Markham whether the job needs a municipal licence or building permit before work starts.
5. **Get it in writing.** Under Ontario law, any home renovation contract worth more than $50 must be in writing, and the final price cannot exceed an estimate by more than 10% unless you agree ([Ontario consumer protection rules](https://www.ontario.ca/page/your-rights-when-starting-home-renovations-or-repairs)).
6. **Keep the deposit small.** Ontario recommends a down payment of no more than 10%, and never paying in full before the work is done.

Name the permit holder in the contract. Markham charges 50% of the permit fee, up to $5,000 for an individual, if work starts before a permit.
