Canada / ISED
ISED published Notice 2025-DRS0006 on 10 September 2025, adopting ETSI EN 301 893 V2.2.1 (2024-11) as the mandatory DFS test standard for 5 GHz WAS/RLAN devices -- Wi-Fi and similar short-range wireless technology -- certified under RSS-247. A six-month transition period allowing the older V1.8.1 (2015-03) standard closed on 20 July 2026, so new certifications for 5 GHz devices must now use the updated test method. RSS-247 Issue 4 also became mandatory in January 2026. Both changes apply across the 902-928 MHz, 2400-2483.5 MHz, 5150-5350 MHz and 5470-5895 MHz bands covered by RSS-247.

ISED published Notice 2025-DRS0006 on 10 September 2025, adopting ETSI EN 301 893 V2.2.1 (2024-11) as the mandatory Dynamic Frequency Selection (DFS) test standard for 5 GHz WAS/RLAN devices certified under RSS-247. DFS testing verifies that a device correctly detects and avoids radar signals when operating in shared 5 GHz spectrum. The notice included a six-month transition period during which the older ETSI EN 301 893 V1.8.1 (2015-03) standard remained acceptable -- that window closed on 20 July 2026, so certifications filed after that date need DFS test results against V2.2.1, not the retired V1.8.1 method.

RSS-247 Issue 4 became mandatory in January 2026, ahead of and independent from the DFS test-standard update that followed later the same year. A product certifying against RSS-247 in 2026 needs to account for both changes together: Issue 4 of the standard itself, and, specifically for 5 GHz devices, the ETSI EN 301 893 V2.2.1 DFS test method that replaced V1.8.1 once the 20 July 2026 transition window closed. Treating either change as optional risks a certification that fails to match current ISED requirements.
RSS-247 covers wireless local area network (WAS/RLAN) devices across the 902-928 MHz, 2400-2483.5 MHz, 5150-5350 MHz and 5470-5895 MHz bands -- the frequency ranges used by Wi-Fi and similar short-range wireless technology built into most consumer electronics and IoT hardware. The DFS test-standard change specifically affects devices operating in the 5 GHz bands (5150-5350 MHz and 5470-5895 MHz), where dynamic frequency selection is required to avoid interference with radar systems sharing the same spectrum. Devices operating only in the sub-5 GHz bands under RSS-247 are affected by the Issue 4 update but not by the DFS-specific change.
Any consumer electronics or IoT manufacturer certifying a 5 GHz Wi-Fi-capable product for the Canadian market under RSS-247 -- routers, smart-home hubs, wearables, and any device with 5 GHz radio hardware. A test report generated against the now-retired V1.8.1 DFS standard is no longer sufficient for a new certification filed after 20 July 2026; testing needs to be re-run against V2.2.1 before a new RSS-247 certification can proceed. Canada joins the other jurisdictions already covered here -- US, EU/UK, Brazil, Mexico, South Korea, Japan, India, Australia and China -- as electronics-import markets with an active, dated compliance requirement rather than a static baseline.
ISED published Notice 2025-DRS0006 on 10 September 2025, adopting ETSI EN 301 893 V2.2.1 (2024-11) as the mandatory DFS (Dynamic Frequency Selection) test standard for 5 GHz WAS/RLAN devices such as Wi-Fi under RSS-247. A six-month transition period allowing the older V1.8.1 (2015-03) standard closed on 20 July 2026, so new RSS-247 certifications for 5 GHz devices must now be tested against the updated standard.
RSS-247 covers wireless local area network (WAS/RLAN) devices across the 902-928 MHz, 2400-2483.5 MHz, 5150-5350 MHz and 5470-5895 MHz bands -- the frequency ranges used by Wi-Fi and similar short-range wireless technology in consumer electronics and IoT devices.

Yes. RSS-247 Issue 4 became mandatory in January 2026, ahead of and separate from the DFS test-standard change that followed later the same year. A product certifying against RSS-247 in 2026 needs to account for both changes -- Issue 4 of the standard itself, and, for 5 GHz devices, the ETSI EN 301 893 V2.2.1 DFS test method that replaced V1.8.1 on 20 July 2026.
The transition period that allowed the older ETSI EN 301 893 V1.8.1 (2015-03) DFS test standard closed on 20 July 2026. New RSS-247 certifications for 5 GHz WAS/RLAN devices filed after that date need to be tested against V2.2.1 (2024-11) -- a test report against the retired V1.8.1 standard is no longer sufficient grounds for a new certification once the transition window has closed.
Adding Canada to a market-access review means checking RSS-247 status against Issue 4 and, for 5 GHz devices, confirming DFS test results are run against ETSI EN 301 893 V2.2.1 rather than the retired V1.8.1 standard. We fold Canada's ISED requirements into the same market-access review we run for the US, EU/UK and the other jurisdictions we cover, so it is one process per product, not a separate one to track per country.
