Is An IP Assignment Clause Enforceable in Canada?
Copyright in Canada is governed by a single federal statute that applies uniformly across every province, including Quebec — so the common-law/Quebec civil-law split that matters for many other clause types has little practical effect here. Employee-created work generally vests in the employer by default; contractor-created work generally requires an express written assignment.
This page describes the general approach Canada law takes to this clause type — it is informational, not legal advice on any specific contract. Enforceability in a real dispute depends on the exact wording, the specific facts, and current law, all of which can change. Have your actual clause reviewed by a lawyer before relying on it.
How Canada approaches this
Unlike contract law generally, intellectual property in Canada — copyright, patents, and trademarks — falls under federal jurisdiction and is governed by uniform federal statutes that apply identically whether the creator or the engaging business is in Quebec or a common-law province. This is a genuine example of the civil-law/common-law distinction not mattering for a particular clause type.
For employees, Canada's Copyright Act generally vests copyright in work created in the course of employment with the employer by default, similar to the UK and Australia. For independent contractors, the contractor generally remains the first owner unless the engagement contract contains an express written assignment.
Quebec's Civil Code governs the underlying employment or services contract itself, but the copyright ownership analysis layered on top of that contract follows the same federal statute as everywhere else in Canada.
What determines the outcome
- Whether the creator is an employee (employer generally owns by default) or a contractor (requires express assignment)
- That IP ownership follows uniform federal law regardless of whether Quebec or a common-law province governs the underlying contract
- Whether the assignment is documented in writing, which is good practice regardless of province
Practical guidance
- Use an express written assignment for every contractor engagement, regardless of province
- Don't assume Quebec's civil law changes the IP ownership analysis — federal copyright law applies uniformly
- Address moral rights explicitly, since Canadian copyright law recognises them separately from economic rights
