(Canada: SAR) ISED Seeks Public Comments on SAR Measurement Criteria for Camera Protrusions
On December 1, 2025, Innovation, Science and Economic Development Canada (ISED) issued Notice 2025-DRS0008, initiating a public consultation on proposed Specific Absorption Rate (SAR) measurement criteria related to camera protrusions on wireless devices.
According to the notice, when a device incorporates a camera module that protrudes beyond the main body, SAR measurement approaches may need to be adjusted depending on several factors, including the height of the protrusion, antenna location, and separation distance from the phantom. In such cases, SAR measurements may be required to be performed with the device positioned parallel to the phantom surface or at a tilted angle, rather than using a single fixed configuration. Based on the measured SAR values and simultaneous transmission conditions, ISED indicated that additional SAR evaluations may be required to ensure compliance with applicable exposure limits.
The deadline for submitting comments is February 10, 2026. Stakeholders are encouraged to review the published notice for detailed technical considerations and submission procedures.
(Canada :WCS) ISED Publishes Draft RSS-195 Issue 3 and SRSP-516 Issue 2 for WCS Equipment in the 2300 MHz Band
ISED has released draft revisions to RSS-195 Issue 3 and SRSP-516 Issue 2, covering Wireless Communications Service (WCS) equipment operating in the 2305–2320 MHz and 2345–2360 MHz frequency bands. The public consultation period concluded on December 3.
These proposed updates aim to support the efficient use of WCS spectrum by reflecting the introduction of advanced technologies such as Active Antenna Systems (AAS) and by refining technical requirements to address potential interference with adjacent band systems.
- 1. RSS-195 Issue 3
-
The draft explicitly defines the 2305–2320 MHz and 2345–2360 MHz bands as 15 + 15 MHz paired blocks, with the updated allocation presented in a dedicated table within the standard.

Maximum transmit power requirements have been introduced for Fixed Stations, Base Stations, and Subscriber Equipment.

- Technical rules have been consolidated to facilitate the deployment of Active Antenna Systems (AAS).
- Protection of Aeronautical Mobile Telemetry (AMT):
To protect non-government AMT systems operating in the 2360–2400 MHz band, the draft specifies that coordination is required when a WCS base station is located within 5 km of an AMT receiving site. - Protection of Satellite Digital Audio Radio Service (SDARS):
New prior notification procedures and interference mitigation requirements have been introduced to ensure coexistence with SDARS operating in the 2320–2345 MHz band.
(Canada: C-V2X) ISED Publishes RSS-252 Issue 3 for C-V2X On-Board Units (OBUs)
On December 12, 2025, ISED released RSS-252 Issue 3, updating the technical requirements applicable to C-V2X On-Board Units (OBUs).
The key update aligns Canada’s regulatory framework with that of the United States by harmonizing channelization and unwanted emission limits in the 5895–5925 MHz band with FCC requirements. This change is intended to support cross-border interoperability and facilitate the deployment of C-V2X systems.
Unlike the FCC approach, ISED did not introduce additional requirements such as geofencing or other location-based control mechanisms as part of this update.
