Canada SMS messaging regulations and restrictions
Articles in this section
Ensure you understand the relevant regulations before sending messages in Canada. All programs are required to be compliant with the regulations outlined in Canada's Anti-Spam Legislation. Your program also needs to comply with the specific country laws, guidelines, and mobile operator policies that continue to evolve and are subject to change without prior notice.
Here is a link to the published best practices for Application-to-person (A2P) messaging that must be followed.
Non-compliant messages may result in your program being blocked and filtered by major carrier networks in Canada.
Clickatell recommends the use of a short code or a Toll-Free Number (TFN) for optimal delivery for A2P (application-to-person) messaging use cases. We'll be phasing out the purchase of new long numbers and for existing long numbers, we recommend that you send no more than one message per second and avoid bulk or burst SMS programs. Should you require a higher sending frequency, please contact our sales team for more options.
