Recognizing that advertising can be an effective means of communicating with the public, either Party may, at its own cost, organize an advertising or public information campaign related to the Building Canada plan. However, such a campaign must respect the provisions of this Agreement. In the event of such a campaign, the sponsoring Party agrees to inform the other Party of its intention as soon as possible, as early notice is essential for any required review process. In any event, notice must be provided a minimum of 20 working days before launch.
