Ontario’s winter climate creates significant challenges for concrete — from early-age freezing to slower strength gain and long-term freeze–thaw deterioration. These conditions directly impact the safety and durability of structural elements such as foundations, slabs-on-grade, retaining walls, an d load-bearing members. Cold-weather concreting is not just a construction task; it’s a structural durability requirement. Concrete placed in winter must meet OBC and CSA A23. 1
