Navigating Canada’s radio compliance landscape just got clearer—and stricter. The Department of Innovation, Science and Economic Development (ISED) has rolled out updated guidelines for RSS-248 compliance, reshaping how modules are certified. Think of it as a traffic cop directing the flow of wireless innovation: no exceptions, no compromises. Let’s break down the critical updates.
LMA Takes the Crown, MA Bows Out
Under RSS-248 Issue 3, Limited Modular Approval (LMA) is now the default for all modules. Full Modular Approval (MA) is officially off the table, with ISED doubling down on stricter oversight. Here’s what this means:
- Indoor subordinate devices are banned from module certification entirely—no MA, no LMA. Treat them as “permanent residents” in their host devices.
- Even if your module ticks every box for MA eligibility (via RSP-100 Form D), RSS-248 overrules: LMA automatically applies.
Why it matters? If your product uses modules, LMA is your new reality. Plan for tighter integration controls.
Legacy Devices Get a Pass (But Don’t Get Too Comfortable)
ISED is cutting some slack for pre-existing setups:
- No retroactive C4PC applications required for hosts already on the market with RSS-248 modules.
- But wait—manufacturers must still self-certify that legacy hosts comply with RSS-248 Issue 3. No free rides here.
For new hosts (not yet launched), the rules tighten: Submit a C4PC application to prove compliance with RSS-248 class requirements.
C4PC Flexibility—With Strings Attached
ISED offers a streamlined path for modules targeting specific host classes:
- A single C4PC application can cover multiple hosts within the same class—but only if RF exposure compliance is identical across all module-host combinations.
- Catch: Need to integrate into a second class? Prepare for another C4PC application.
Pro tip: Ensure your CB certificate includes clear conditions limiting module installation to designated host classes. Installation instructions are your legal shield.
