Overview: Civil, Structural and Environmental Engineers
You call an engineer when a decision needs a professional seal behind it. The crack in the basement wall keeps getting wider. A renovation takes out a bearing wall. The township wants a lot grading plan before it will look at your addition. A buyer asks what the old gas station on the corner left in the soil.
Engineering is licensed by each province and territory, not by Ottawa. Only someone licensed where the house sits can call themselves an engineer there and seal your drawings. Some provinces license the firm as well, like Ontario with its certificate of authorization and BC with its permit to practice.
House jobs are small and very local. Footings go below frost. A roof change gets checked against the snow load the building code sets for your area. In Quebec, a septic permit application needs a site study from a member of a professional order. Around Trois-Rivières, cracked foundations have been traced to pyrrhotite in the concrete.
Our listings show what each firm states on its own website, from structural reviews to soil, drainage and septic work. Start with your province, then your city, to find engineering firms near you.
Engineering assessment and design fees in Canada
Request a fee for a defined deliverable. Site investigations, laboratory testing and construction monitoring may need separate budgets.
| Service | Estimated budget | What it covers |
|---|---|---|
| Structural site assessment | C$350–C$800per assessment and report | Assessment of one defined residential structural concern with accessible conditions.What this estimate coversIncludes in this budget: Site visit; Written findings Budget separately or confirm: Opening concealed areas; Repair design |
| Beam or wall-removal design | C$800–C$1,800per defined design package | Engineering for one ordinary residential wall opening under Part 9, with existing conditions documented.What this estimate coversIncludes in this budget: Calculations; Agreed sealed drawings Budget separately or confirm: Construction; Unlisted revisions |
| Lot grading or drainage design | About C$1,990per lot plan | Stamped grading, drainage and servicing package for a single-dwelling lot using an existing topographic survey.A planning allowance for the stated scope; the final quoted amount can differ.What this estimate coversIncludes in this budget: Engineering design and stamped drawings Budget separately or confirm: New topographic survey and municipal fees; Physical grading and later compliance certification |
| Phase I environmental site assessment | C$2,000–C$5,000per assessment | Defined property review with records research, site visit and report scope stated.What this estimate coversIncludes in this budget: Records review; Site assessment report Budget separately or confirm: Sampling and laboratory tests; Remediation |
| Phase II investigation | C$7,000–C$60,000per investigation scope | Sampling investigation designed around identified concerns, with sampling locations and tests specified.Sampling locations, depths, contaminants and reporting requirements must be scoped; complex sites can exceed this range.What this estimate coversIncludes in this budget: Listed fieldwork; Listed laboratory tests and report Budget separately or confirm: Remediation; Unplanned additional sampling |
What changes the price
- The issue being assessed and adequacy of existing drawings
- Number of samples, specialist tests and site-access constraints
- Required submissions, revisions and construction-stage attendance
Ask before accepting a quote
- What exact report or sealed drawing package will I receive?
- Which field investigations, laboratory tests and disbursements are included?
- What finding would trigger a separate investigation or additional design fee?
Separate investigation and remediation
- Assessment findings can define the next stage; they do not include every possible repair.
- Agree on approval before additional sampling, redesign or site visits.

Frequently asked questions
Can a designer draw my permit plans instead of an engineer?
In Ontario, often yes. Much of the design work for a house permit can come from a designer who passed the province's building code exams and holds a BCIN, and the province keeps a public registry of them. An owner drawing plans for their own house is mostly exempt from that qualification. The building department can still ask for an engineer's seal on part of the job, such as a beam or a retaining wall.
What happens on a structural assessment visit?
The engineer reads the crack from inside and out, checks doors and floors for level, and follows the load down to the footing. Expect questions about frost heave, downspouts dumping beside the wall and recent digging next door. In Quebec, the cause can be mineral rather than soil. The RBQ explains that pyrite under a slab can heave and crack it, and pyrrhotite can crack concrete.
Who is allowed to seal the drawings?
A professional engineer licensed in the province where the house sits. Each province and territory licenses its own engineers, and the title is protected by law. Firms can need their own authorization too: Ontario wants a certificate of authorization from anyone offering engineering to the public, and BC requires a permit to practice. Look the name up with the regulator, such as PEO in Ontario, which keeps a public directory.
Who designs a septic system for a rural home in Quebec?
Someone from a professional order has to study the site first. Under Quebec's rules for isolated homes, the septic permit application goes to the municipality with a study of the site and soil, done by a member of a relevant professional order. For some systems on impermeable soil, an engineer or a geologist must sign that study. Get the permit before any digging starts.
What is an environmental site assessment?
It's a staged check for contamination. Phase one is records and a site walk: past uses, old tanks, spills next door. Sampling only follows if that turns something up. In Ontario, it matters most when land moves to a more sensitive use, like homes on a former factory or dry cleaner site. A record of site condition has to be filed first, and a licensed engineer or geoscientist leads that work.
