The Role of Structural Engineering
What Does a Structural Engineer Do in Ontario?
A structural engineer analyzes and designs the load-bearing elements of a building — foundations, beams, columns, walls, and roof structures — to ensure they are safe, code-compliant, and capable of handling all expected forces.
In Ontario, structural engineering is required by municipalities for most permit applications involving new construction, additions, or significant renovations. At MAY Engineering, every design is reviewed for Ontario Building Code (OBC) compliance — so your permit is approved without delays.

Structural Engineering & Ontario Building Code Compliance
All MAY Engineering structural work is designed to meet the Ontario Building Code (OBC) effective January 2025. When you submit for a building permit, your structural drawings must demonstrate full OBC compliance — otherwise the municipality rejects the application and you're back to square one.
We build OBC compliance into every design from the start. Your stamped drawings are accepted on first submission, which means fewer delays, lower costs, and a smoother path from design to construction.
