Canada
Radio communications in Canada are regulated by a branch of Industry Canada called Radio Communications and Broadcasting Regulatory Branch together with Canadian Radio-television and Telecommunications Commission (CRTC). This means, interested parties must apply for both a certificate from Industry Canada and a license from CRTC in order to operate a radio station. Industry Canada manages the technicalities of spectrum space and technological requirements whereas content regulation is conducted more so by CRTC.
LPFM is broken up into two classes in Canada, Low (50w) and Very Low (10w). The transmitters therefore range from 1-50 watts, as opposed to 1-100 watts in the U.S. As of 2000, 500 licenses (very low and low power FM) have been issued. These transmitters are generally only allowed in remote areas.
The regulation of spectrum space is strict in Canada, as well having restrictions on 2nd and 3rd adjacent channels along with other protections for AM and FM commercial radio. In addition, because there have been a few cases that found that FM frequencies have caused interference to the aeronautical navigation and communications (NAV/COM) spectrum, (though evidence is not very concrete presently) pirate radio regulation has remained very strict as well. However, the two regulating bodies do have certain exemptions. For example, low power announcement transmitters that meet the requirement of Broadcasting Equipment Technical Standards 1, Limited Duration Special Events Distribution Undertakings, Temporary Resource Development Distribution Undertakings, and Public Emergency Radio Undertakings are a few instances, which according to certain criteria, may be exempt from certificate/license requirements.
In Canada, there is no formal transmission power below which, a television transmitter is broadcasting at low power. Industry Canada, in most cases, considers a television transmitter to be low power if the noise-limited bounding contours are less than 20 km from the antenna.

“I fear that I have not got much to say about Canada, not having seen much; what I got by going to Canada was a cold.”
—Henry David Thoreau (1817–1862)
“Though the words Canada East on the map stretch over many rivers and lakes and unexplored wildernesses, the actual Canada, which might be the colored portion of the map, is but a little clearing on the banks of the river, which one of those syllables would more than cover.”
