Profession Playbook
Quantity surveying is the profession most people discover by accident — the cost brain of construction, imported from the UK tradition, chronically short of people in Canada. The questions: QS vs estimator (related but not the same), consulting vs contractor side, whether the PQS is worth it here, and why UK/international QSs keep being recruited into Canada. (Because there aren't enough — which is your opportunity.)

Same credential, different money, depending on where you take it.
Pricing real bids for a GC or trade contractor — faster, riskier, closer to the work, and your number wins or loses the job.
Best for: People who like the competitive bid game and contractor culture.
Every figure above is what quantity surveyors get paid. It is not what you charge once you run your own cost consulting practice. 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 jobDirector and partner in cost consultancies, your own practice (low overhead, scales on reputation), or laterally into development, project management, lending/loan monitoring, and claims/expert work. The cost skillset is one of the most portable in construction — everyone from banks to owners to contractors needs someone who knows what things actually cost.
AEC Stack handles incorporation, insurance, proposals, invoicing, and chasing the money, so a cost consulting practice runs with an office behind it from the first client.
