Jamming Devices are Prohibited in Canada:That's The Law

July 2011

The importation, manufacturing, distribution, offering for sale, sale, possession and use of radiocommunication jamming devices in Canada are prohibited under sections 4, 9 and 10 of the Radiocommunication Act.

What is a radiocommunication jamming device?

A radiocommunication jamming device, also known as a signal silencer, blocker or disabler, is a radiocommunication transmitter designed to interfere with, disrupt, or block radiocommunication signals and services. Although most jamming devices are manufactured for the purpose of disrupting the functioning of wireless cellular networks and low-power communication devices (cordless telephones and cameras, Wi-Fi networks and reception of GPS signals), they can also prevent communication to emergency services (9-1-1, ambulance, fire, police, aeronautical service, etc.).

Over the past few years, Industry Canada has encountered several cases of illegal importation, possession and use of radiocommunication jamming devices.


A conviction under the Radiocommunication Act carries a fine of up to $5,000 and/or imprisonment not exceeding one year (individual) or a fine of up to $25,000 (corporation), as well as forfeiture of the radio apparatus and possibly an injunction to refrain from activity related to the offence.

For further information on the associated Canadian regulations, please consult: http://www.ic.gc.ca/eic/site/smt-gst.nsf/eng/sf01329.html.

Importation of Equipment

In Canada, radio apparatus, interference-causing equipment and terminal equipment are subject to Canadian regulations. Canadian consumers and others seeking to import radio transmitting equipment into Canada should verify that the equipment meets Industry Canada's technical regulations prior to making any purchases. Jamming devices may be detained or seized at the border, and the importer may, on prosecution, be liable to a fine or to imprisonment.
