Load Bearing Wall Removal Permit Drawings in Ontario
Removing a load bearing wall in Ontario requires a building permit and professional structural drawings. Ontario Design Studio prepares BCIN-certified permit drawings coordinated with Professional Engineer (P.Eng) structural designs for load bearing wall removals across Ontario. This is one of the most common — and most misunderstood — renovation projects we handle.
Why Load Bearing Wall Removal Requires a Permit
Load bearing walls support the structural loads above them — floor joists, upper storeys, and the roof. Removing one without proper engineering creates a risk of structural failure, sagging floors, cracked drywall, and potentially dangerous collapse. The Ontario Building Code requires that any structural modification be designed by qualified professionals and approved through a building permit.

Frequently Asked Questions
Do I need a permit to remove a load bearing wall in Ontario?
Yes. Removing a load bearing wall in Ontario requires a building permit and professional structural drawings. You'll need a BCIN-certified designer for the permit drawings and a Professional Engineer (P.Eng) for the structural design showing the replacement beam, post locations, and load transfer path.
How do I know if a wall is load bearing?
Load bearing walls typically run perpendicular to floor joists and support the weight of the structure above. However, walls parallel to joists can also be load bearing in some configurations. Never remove a wall without professional assessment — our team can help you determine which walls are structural.
