Law for Professional Practice

This module covers the general law that shapes the day-to-day work of professional engineers and geoscientists in Canada: how the legal system is structured, how contracts are formed and enforced, how the tendering process is governed, when a professional becomes liable in negligence, and the practical doctrines (limitation periods, business structures, employment, intellectual property, dispute resolution, and insurance) that affect practice and personal risk. The NPPE tests application, not memorization. You should be able to read a short scenario and identify which doctrine or landmark case controls the outcome. Throughout, the two anchor texts are Marston's Law for Professional Engineers and Andrews, Shaw & McPhee's Canadian Professional Engineering and Geoscience: Practice and Ethics. Statute details vary by province; this module teaches the common-law principles that apply nationally and flags where provincial statutes govern.

Canada has two legal traditions. Nine provinces and the three territories use common law, which is built from judges' decisions over time. Quebec uses a civil law system for private matters, governed by the Civil Code of Québec, a comprehensive written code that judges apply rather than build on. Criminal law and most federal matters are common-law and statutory across the whole country.

Two sources of law operate together. Statute law is enacted by Parliament or a legislature (the engineering/geoscience acts that create your regulator are statutes). Common law is judge-made law filling gaps and interpreting statutes. Where they conflict, valid statute prevails over common law.

Courts are arranged in a hierarchy: provincial trial courts, then provincial courts of appeal, then the Supreme Court of Canada at the top. This hierarchy makes precedent work through stare decisis, "to stand by decided things."

Precedent rule: A court is bound by decisions of higher courts in its own chain, and persuaded (but not bound) by courts of equal rank or other provinces. Only the Supreme Court of Canada binds everyone.

For practitioners, this means a single appellate decision can reshape an entire area of professional liability. This is exactly why the landmark cases below matter.
