Here in Canada it is illegal to listen to Police, Fire, or Paramedic radio broadcasts, for the purpose of making money from the information derived from listening in. Most of those types of frequencies in Canada are now encrypted so that private individuals cannot hear them. Authorized media outlets, like radio and TV news have to apply to the Federal Government to get a permit to listen. Private companies, like industrial plants, taxi services, courier services and the like, can be heard if you buy a channel index book, sold at radio stores that lists frequencies by geographical locations.
