Just to help understand the issue this is a note posted here on rc forums about this issue its from an industry Canada officer
The 902 to 928 MHz ISM (Industrial, Scientific and Medical) band is a licence exempt band in Canada as long as the proposed transmitter is certified for use in Canada. Certified devices operating in the 902-928 MHz band are limited to 1 watt or 4 watts E.I.R.P (Effective Isotropic Radiated Power). You may search the Radio Equipment List (REL) to determine if the device has been certified for use in Canada by visiting our web site at http://www.ic.gc.ca/app/sitt/reltel/....do?lang=engAn
Amateur Radio Operator with Basic Qualifications may operate in the 902-928 MHz band with an emission bandwidth of up to 12 MHz as long as their radio transmissions do not cause interference nor are protected from interference from stations licensed in other services operating in that band.
Please contact the undersigned if you require any additional information.
Although it was talking about the 900 band I think the ism band also applies to 5.8
Hope that's helpful fb
