Steel building permits in Canada
A pre-engineered steel building requires a building permit in virtually every Canadian municipality, regardless of size or use. The permit process validates three things: the structure meets code, the site plan respects zoning, and the owner has accepted responsibility for the work.
The good news: because we issue stamped structural drawings with every project, the structural portion of your permit package is effectively pre-approved. Most of the work on your end is coordinating site plan, foundation engineering, and local review.
National Building Code of Canada 2020
Every steel building we design meets the 2020 National Building Code of Canada (NBC 2020) for design loads, structural integrity, and material standards. Specifically:
- 01
Part 4: Structural Design
All primary and secondary framing is designed to Part 4 loads: dead, live, snow (Ss/Sr from NBC Appendix C), wind, and seismic. Use our climatic data map to look up your exact site values.
- 02
CSA S16-19: Steel Design
Connections, member selection, and fabrication follow the current Design of Steel Structures standard, including welding, bolting, and corrosion protection.
- 03
CSA W47.1 / W59
Our fabricator is certified to CSA W47.1 Division 2 and welds to W59. Every weld procedure is qualified; every welder is current.
- 04
Provincial amendments
Each province adopts NBC with local amendments: Ontario OBC, Quebec CCQ, Alberta ABC, BC BCBC, etc. We apply the applicable provincial edition for your project.
What you get in a stamped drawing package
After design approval, we issue a complete stamped structural package, sealed by a professional engineer licensed in your province. Every permit reviewer gets the same set:
- 01
Anchor-bolt plan
Plan view, column reactions, bolt spec, embedment, and templating notes. This is what your foundation engineer and GC use to pour footings.
- 02
Structural erection drawings
Primary frames, bracing, purlins, girts, eave struts, sheathing layout. Marked, dimensioned, and cross-referenced to the fabrication BOM.
- 03
Design loads and load combinations
Ss, Sr, wind pressures, seismic Sa values, occupancy category, risk category. This is the page the reviewer looks at first.
- 04
Member schedules and connection details
Moment and shear connections detailed to the bolt. Weld call-outs per W59. Sheet metal fastener patterns per manufacturer spec.
- 05
Professional engineer's seal
Original PE stamp, signature, and sealing date on every sheet. Valid for permit submission anywhere in the province of issue.

We'll send a redacted sample structural package so you can review with your reviewer or design consultant before committing. Request a sample.
Permit timelines by province
Municipal review time is the biggest variable in your overall project timeline. Rural townships sometimes turn permits in 2 weeks; major cities can take 6–12 weeks depending on backlog and project complexity. Plan for the upper end.
Typical municipal building-permit review times (2025)
| Region | Simple review | Complex / site-plan | Rezoning req. |
|---|---|---|---|
| Rural ON / QC / MB | 2–4 weeks | 4–8 weeks | 3–9 months |
| GTA / Greater Montreal | 6–10 weeks | 10–16 weeks | 6–18 months |
| Calgary / Edmonton | 4–8 weeks | 8–14 weeks | 6–12 months |
| Vancouver / BC Lower Mainland | 8–14 weeks | 12–20 weeks | 9–18 months |
| Atlantic provinces | 3–6 weeks | 6–10 weeks | 3–9 months |
Permit process, step by step
- 01
1. Zoning and site plan check
Before engineering anything, confirm the use is permitted and the building fits setbacks and coverage. For commercial and industrial, this often requires a formal site plan approval step before a building permit is even accepted for review.
- 02
2. Engineering design
We finalize size, loads, and structural system. Any owner-supplied design features (cranes, mezzanines, tall racking) are engineered in at this stage.
- 03
3. Stamped structural package
We issue the sealed drawing set and calculations. Your foundation engineer designs footings to our column reactions and seals their own drawings.
- 04
4. Permit submission
You (or your expediter) submit structural + foundation + architectural + mechanical/electrical to the municipality. Plan for a Part 3 building to need more than a Part 9 one.
- 05
5. Reviewer comments and resubmission
Expect 1–2 rounds of comments. We respond to any structural questions directly, in writing, on your behalf. No cost, no back-and-forth through you.
- 06
6. Permit issued, fabrication starts
Fabrication overlaps with the permit process. By the time the building is ready to ship, your foundation is poured and cured. 20–26 weeks total is typical on an 80' × 200' industrial project.
We respond to reviewers directly
Your municipality can email our PE with structural questions. We answer in writing, cc you, and keep the permit moving. This is included with every project.
