Any electronics company that sends OTA firmware updates, installs companion apps, or sends commercial messages to Canadian users must comply with CASL's express consent requirements, or face penalties up to CAD $10 million per violation per corporation.

Under CASL Section 8, it is prohibited to install a computer program on another person's computer system — or cause such installation — without that person's express consent. This provision covers IoT devices, connected hardware, smart home devices, and any electronics product that installs software (including firmware updates) on a user's system. ### Express consent for software installation on connected devices CASL requires express consent for software installation — implied consent is not sufficient for software. For connected hardware, this means: before installing any application, firmware, or software program on a user's device (including OTA updates that add new functionality), the user must have expressly consented in a manner that meets CASL's consent requirements. The consent request must clearly describe the function and purpose of the program; identify the person seeking consent; and obtain a positive opt-in action (not pre-checked boxes or default consent). ### OTA firmware updates and CASL compliance Over-the-air (OTA) firmware updates that add new functions or capabilities — rather than purely fixing security vulnerabilities or restoring existing functionality — are the primary CASL compliance risk for IoT and connected hardware companies. A firmware update that installs new tracking features, adds a new service integration, or enables new data collection requires express consent before installation in Canada. Security-only updates that restore the device to previously-consented functionality benefit from an implied consent interpretation under CASL guidance. ### Commercial electronic messages (CEMs) and connected device communications CASL's commercial electronic message (CEM) provisions require consent and specific disclosure (sender identification, unsubscribe mechanism) for emails, text messages, and other electronic messages sent for commercial purposes. For hardware companies with companion apps, device-linked accounts, or cloud services, CEMs sent to Canadian users in connection with the device (promotional emails, feature announcements, marketing messages sent through the companion app) are subject to CASL CEM rules. Transactional messages (purchase confirmations, account security alerts) are not CEMs and do not require prior consent. ## CASL compliance steps for connected device manufacturers 01 Audit all software installation events in your connected device's lifecycle: initial setup, OTA firmware updates, companion app installations, and any third-party integrations — each installation event that adds new functionality requires separate CASL-compliant express consent from Canadian users. 02 Review your OTA update mechanism: categorise updates as security/maintenance (restoring previously-consented functionality — generally compliant) versus feature additions (new functionality requiring fresh consent) — if you cannot cleanly separate these, treat all OTA updates as requiring consent. 03 Implement a CASL-compliant consent mechanism for software installation: the consent request must describe the program's functions, identify your company, and require a positive opt-in action — do not use pre-checked consent boxes or rely on EULA acceptance alone as CASL consent. 04 Review your companion app's push notification and in-app messaging for CEMs: promotional messages sent through the app to Canadian users require prior express or implied consent and must include an unsubscribe mechanism. 05 Maintain consent records for all CASL consents obtained: record the date, time, method of consent, and the consent request text shown to the user — CASL enforcement places the burden of proof of consent on the sender/installer, and consent records are your primary defence. 06 Implement an unsubscribe mechanism for all CEMs that meets CASL standards: the unsubscribe mechanism must process requests within 10 business days, must be functional for at least 60 days after the CEM is sent, and cannot impose a fee or require more than identifying information from the user. 07 For devices shipped with pre-installed software, review whether CASL's transitional consent provisions apply — CASL had transitional provisions for pre-existing relationships, but these have expired, and all new installations or updates require current compliant consent. ## Frequently asked questions ### Does CASL apply to hardware companies based outside Canada? Yes — CASL applies to software installation on computer systems located in Canada, and to commercial electronic messages sent to or accessed from electronic addresses in Canada. A hardware company based in the US, EU, or Asia that sells connected devices to Canadian consumers and sends OTA updates or marketing emails to those consumers is subject to CASL for those activities. CRTC (the Canadian Radio-television and Telecommunications Commission) has jurisdiction over CASL violations affecting Canadians regardless of where the violating company is based. ### What are the penalties for CASL violations? CASL carries significant civil penalties. For individuals, penalties can reach CAD $1 million per violation. For corporations, penalties can reach CAD $10 million per violation. Each prohibited software installation or non-compliant CEM can constitute a separate violation. CRTC has issued enforcement notices and undertakings to companies for CASL violations, and the private right of action (though not yet in force as of 2026 for certain provisions) would allow affected individuals and organisations to sue directly. ### Is installing a security patch without consent a CASL violation? Security patches that fix known vulnerabilities without adding new functionality are generally understood to fall within the implied consent exception — the user's original consent to use the device and its software implicitly covers maintaining the security of that existing functionality. However, CASL guidance is not entirely clear on this point, and the safest practice is to disclose your security update policy at the time of initial device setup, including that security patches may be applied automatically, so users are aware and consent is documented. ### How does CASL interact with PIPEDA and Canada's privacy laws? CASL and PIPEDA (Personal Information Protection and Electronic Documents Act) operate in parallel. CASL governs the installation of software and the sending of CEMs; PIPEDA governs the collection, use, and disclosure of personal information. A CASL-compliant OTA update that adds new data collection functionality also requires a PIPEDA-compliant privacy consent for the new data collection. Connected device companies operating in Canada must satisfy both frameworks — CASL for the installation act and PIPEDA for data privacy, and Quebec's Law 25 for Quebec-resident users. **Disclaimer:** Educational resource only. CASL interpretation by CRTC continues to evolve.
