OTTAWA - Canada's telecommunications regulator is looking at tweaking its telemarketing rules just weeks after introducing a national do-not-call list.

The CRTC says it's considering exempting electoral candidates who are not members of political parties from the list.

Only candidates that are members of registered political parties are presently exempted from being listed in the national registry.

The CRTC is also brainstorming ways to track and remove from the list numbers that have been disconnected or re-assigned.

And the commission may also harmonize its telemarketing rules with provincial laws that restrict the hours in which auto-diallers can be used.

More than 3.3 million telephone, cellular and fax numbers have been registered on the do-not-call list since it was launched Sept. 30.
