Small calls are your trade, and the licence draws the line
A door that rubs, two shelves, a hole in the drywall, furniture to assemble: your customer calls with a list, rarely with a project. The value is in grouping — several small jobs in one visit, within the week — and in a request where every item is written down, with its room and its photo. A written work order beats a verbal agreement even on a small package: your receptionist lays the groundwork for one during the call.
In Quebec, the licence sets what you can accept. The provincial building authority (RBQ) requires a licence from anyone who does construction work for others for profit, and profit includes a direct or indirect benefit. The exemption the RBQ grants for renovation, repair or maintenance work below a value threshold covers owners doing the work themselves on their own property; when that owner hires a contractor, the RBQ states that the contractor must hold the appropriate licence. Electrical and plumbing work also require a licence, and according to CAA-Québec, work in a rental unit requires a certificate of competency from Quebec’s construction commission (CCQ).
So your receptionist does not apply a licensing rule on your behalf: she applies your list. She accepts the jobs you do, politely names the ones you do not, and separates anything involving electrical, plumbing or gas from the request. When someone asks whether you are licensed, she gives the number you gave her, and only that one.
