The non-compete gets the attention because it is the clause that sounds like a wall. It is also the clause most likely to fall, because Canadian courts treat a restraint on earning a living as presumptively unenforceable and put the burden on the employer to justify every element of it: the activity restricted, the geography, the duration. What survives that scrutiny is rarely the broad prohibition on competing. It is the quieter set of terms sitting underneath, which courts enforce with far less hesitation, and which in practice decide whether a move is workable.
Two clauses, two very different standards of review
The Supreme Court of Canada set the frame in Elsley v. J.G. Collins Insurance Agencies, and the logic has not moved much since. A non-solicitation covenant protects the employer's connection with its customers without stopping the departing employee from working in the field at all, so a court will ask whether a non-compete was necessary when the narrower clause would have done the job. Usually the answer is no. The practical consequence for anyone weighing an offer is that the clause forbidding contact with a defined list of clients is the one likely to bind, while the clause forbidding employment with a competitor is the one likely to be struck out whole, since Shafron v. KRG Insurance Brokers closed the door on judicial rewriting.
What confidentiality reaches, and what it cannot
Confidentiality obligations are enforced readily because they do not stop anyone from working. They stop a specific use of specific information. The line courts draw is between the employer's genuine confidential material, meaning pricing formulas, margin structures, customer lists compiled at cost, unreleased product plans, and the general skill, knowledge and professional judgment an employee accumulates and carries out the door as a matter of right. A careful reader checks the definition clause before the operative clause, because a definition that sweeps in "all information relating to the business" without a carve-out for publicly available material and for the employee's own know-how is the part that will be argued about, and the part worth negotiating before signature rather than after departure.
Fiduciary duty arrives without a signature
Senior employees carry obligations no contract created. Canadian Aero Service v. O'Malley established that a director or senior officer cannot divert a corporate opportunity the employer was actively pursuing, and RBC Dominion Securities v. Merrill Lynch confirmed that even non-fiduciary employees owe duties of good faith on exit, with a branch manager held liable for organizing a coordinated departure. The test is functional, not titular. A vice-president of sales with real discretion over pricing and accounts may be fiduciary; a senior-sounding individual contributor usually is not. Anyone who has signed nothing at all should still assume that recruiting the team and taking the pipeline are separate acts with separate consequences.
The IP clause signed on day one
Assignment-of-inventions language is the least read and among the most durable. Under the Copyright Act, work created in the course of employment generally belongs to the employer by default, and most contracts extend that by assigning patents, designs and improvements as well, often with a waiver of moral rights attached. The questions worth asking are about scope and timing: does the assignment capture work made outside working hours, on personal equipment, unrelated to the employer's business, and does it reach for a trailing period after the last day. A clause with no subject-matter limit is the one that turns a side project into litigation, and it is easier to narrow at the offer stage than to argue about later.
Reading the package in the order that matters
Start with non-solicitation and read the definitions: whether "client" means anyone on a database or only accounts the employee personally served in the final twelve months, whether "solicit" also covers accepting unsolicited inbound business, and whether the staff clause is a no-solicit or a harder no-hire. Then read the confidentiality definitions, the IP scope, and the survival clause that says which terms outlive the employment. The non-compete is last, because whether it holds may not change the answer. In the United States, the Federal Trade Commission oversees non-compete practice as a competition question; in Canada, the analysis stays with the courts and, in Ontario, with the statutory ban that leaves non-solicitation untouched.
An hour with an employment lawyer, contract in hand, generally produces a map rather than a verdict: which clauses are live, which are likely dead, and which client relationships are actually off limits for how long. That map is what makes the next job offer answerable.
