In the amateur radio service, business communications:

The amateur radio service is strictly a non-commercial, hobbyist service. Canadian regulations explicitly forbid the transmission of business, commercial, or pecuniary (financial) communications over amateur frequencies at any time. This strict rule preserves the purely amateur and volunteer nature of the radio bands. Distractors suggesting exceptions for emergencies or specific bands are completely incorrect. While emergency situations allow for special types of communications to protect life and property, conducting business transactions or commercial operations over amateur radio remains prohibited without exception.
