I may be wrong, but it appears that the rules for unlicensed TV in the U.S. are part of a larger initiative to use the ‘white space’ amongst the unused TV channels. Other devices will also be permitted. It also appears that they need to be certified.
Canada is lagging behind, and while I found several discussion papers and a framework on the use of the white space, I could find no hard and fast rules.
