Construction Management Magazine News has reported that the 105 Victoria Street building will include 2000m² of green space and terraces.

Canada: CarbiCrete has obtained the first Environmental Product Declaration (EPD) for its cement-free concrete masonry units (CMUs). The products have specific CO₂ emissions of 11.7kg/m³ for the CMUs, 94% below the industry norm of 200kg/m³. FinancialWire News has reported that CarbiCrete’s recipe for the CMUs replaces cement with steel by-products, while also sequestering CO₂.

Concrete products company Canal Block is set to commence production of CarbiCrete CMUs at its Port Colborne plant in Ontario in early 2025.
