Geotech is the discipline you either love or fall into — and the questions reflect its split personality: the field side (boots, boreholes, mud) versus the office (analysis and reports), why it pairs with drilling and a soils lab, and whether the lower starting pay pays off later. (It can — good geotechs are scarce, and the work is hard to offshore.)
Where it starts
$58k–72k
EIT (geotechnical)

Ontario figures for geotechnical engineer, from the first role after school to the top of the practice. Approximate, and worth checking against current postings and association salary surveys.
| Stage | Pay | What is going on at this stage |
|---|---|---|
| EIT (geotechnical) | $58k–72k | Field-heavy early — site investigations and drilling supervision. |
| P.Eng (geotechnical) | $85k–105k | |
| Senior geotechnical engineer | $105k–135k | |
| Associate / principal | $135k–180k+ | |
| Firm owner | Equity, variable | A geotech firm needs drilling and lab capability — capital-heavy. |
Every figure above is what geotechnical engineers get paid. It is not what you charge once you run your own geotechnical engineering firm. Your rate has to carry the hours you are not on the tools, the truck, the tools themselves, WSIB, insurance, the quote you wrote and lost, and the holdback sitting in someone else's account for 60 days. Contractors who set their rate off their old hourly wage are the ones who work every weekend and still cannot say whether the year was profitable.
The step from paid by the hour to paid by the jobSenior/principal, your own geotech firm (paired with drilling and lab capability), or laterally into environmental, mining, or heavy-civil specialties. Because good geotechs are scarce and the field experience is hard to fake, the discipline has strong job security and a clear path to high-value senior and specialist roles — even if the starting pay lags.
AEC Stack handles incorporation, insurance, proposals, invoicing, and chasing the money, so a geotechnical engineering firm runs with an office behind it from the first client.
