Choosing who prepares your building permit drawings is a decision worth thousands of dollars - and one you should be able to verify, not just take on faith. Below is the proof behind Ontario Design Studio: credentials you can independently confirm, real approved permits, and the qualities our clients tell us matter most. As we grow our public review profile, verified client reviews will appear here too.
Proof You Can Verify
- BCIN-Certified - our registration is public. Confirm it yourself on the Ontario Ministry of Municipal Affairs and Housing’s QuARTS registry before you hire anyone, including us.
- Real, approved permits - see our portfolio of actual drawing sets, including a garage conversion stamped and approved by the City of Mississauga Building Division.
- An engineering-informed founder - a civil-engineering background and years on active construction sites, not just drafting. More about us.
Our promise: we will never post a fake review. Every review shown on this page will be a genuine, verifiable one from a real client - the same standard we hold our drawings to.
What Clients Tell Us They Value
Across residential and commercial projects, the same themes come up again and again:
- First-time approvals. Complete, coordinated submissions mean fewer examiner comments and less waiting.
- Plain-English guidance. We explain zoning, fire separation, and egress in language a homeowner can actually follow.
- Responsiveness. Quotes usually within 24 hours, and drawing packages typically ready in 5–10 business days.
- They handle the paperwork. From measurement to municipal submission and deficiency responses, we manage the process end to end.
