SMS Country regulations and restrictions

Canada

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.

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 for optimal delivery for A2P (application-to-person) messaging use cases. When using a long number, we recommend that you send no more than one message per second, and avoid any bulk or burst SMS programs. Should you require a higher sending frequency, please contact our sales team for more options.
