Permits and licences
Permit fees for residential concrete work typically run CA$100 to CA$500, and some urban municipalities charge more for larger projects. Licences depend on the province. In British Columbia, a residential builder needs a provincial licence, with an application fee of CA$600. In Québec, contractors apply for a construction licence from the RBQ, which publishes the fees for applications and exams. In Ontario, a licence is needed to build or sell a new home, with owner-builder exceptions. Ask your contractor which permits and licences apply to your job.
Season and timing
Winter runs December to February, and frozen ground makes digging and pouring concrete hard across most of the country. The sources we checked give no cold-weather rule, so ask the contractor how they protect fresh concrete in frost. A November request lets you book the work for spring, when the ground thaws.
How it is bought here
Concrete is quoted per cubic metre (m³), slabs per square foot or square metre, and labour per hour. Ontario concrete contractors commonly charge CA$60 to CA$100 an hour, and a small repair such as a step can cost CA$300 to CA$1,000. Check whether a price includes materials, reinforcement and removal of old concrete.
What to write in the request
Describe the work needed (a slab, a foundation, a crack repair or steps), the dimensions or volume in metres or feet, and the soil and plot conditions. Say whether reinforcement is needed, the site address and the deadline. Add your budget, so the contractor can suggest materials that fit it.
