There are significant differences between Canada's anti-spam law, CASL, and the U.S. CAN-SPAM. Key differences include:

1. CASL is opt-in, while CAN-SPAM is opt out;

2. Canada has an opt-in exception for existing business relationships that must be renewed every two years; and

3. CASL applies not only to email but to any electronic message, including a message sent via an installed program.
