How to Hire a Concrete Contractor in Ontario
Concrete work in Ontario is highly weather-dependent — pouring concrete below 5°C causes it to freeze before curing, leading to cracking and failure. The best concrete season is May through October. Foundation work and retaining walls over 1 metre typically require a building permit under the Ontario Building Code.
