Consumers should understand that registering on the National DNCL will reduce but not eliminate all telemarketing calls. There are certain kinds of telemarketing calls that are exempted from the National DNCL Rules.

The exemptions include telemarketing calls made by, or on behalf of:

Canadian registered charities;
Political parties, riding associations and candidates; and
Newspapers of general circulation for the purpose of soliciting subscriptions.
Telemarketing calls from organizations with whom you have an existing business relationship are also exempt. You are considered to have an existing business relationship with a telemarketer if you:

Purchased, leased, or rented a product or service in the last eighteen (18) months from the telemarketer;
You have a written contract with the telemarketer for a service that is still in effect or expired within the last eighteen (18) months; and/or
You asked a telemarketer about a product or service within the last six (6) months.
Telemarketers may also call you if you have provided express consent to be called. Express consent includes:

Your permission on a written form, electronic form, or an online form; or
Your verbal permission.
The National DNCL Rules to not apply to telemarketing calls made to businesses.

What can you do to reduce telemarketing calls that are exempt from the National DNCL Rules?

If you do not want to be called by a telemarketer making an exempted call, you can ask to be put on the telemarketer’s own specific do not call list. Every Canadian telemarketer is required to maintain such a list and respect your wishes not to be called. Organizations conducting market research, surveys, or public opinion polls are not required to keep their own specific do not call lists.

What about calls from market research or polling firms?

Calls from organizations conducting market research, surveys, or public opinion polls are also exempt from the National Do Not Call List Rules and are not required to keep an internal do not call list. These types of calls are not telemarketing calls because the caller is not asking you to purchase, lease or rent products or services.
