Regulations Respecting Non-mailable Matter Whereas, pursuant to section 20 of the Canada Post Corporation Act, a copy of the proposed Regulations respecting non-mailable matter, substantially in the form set out in the schedule hereto, was published in the Canada Gazette Part I on July 22, 1989 and a reasonable opportunity was thereby afforded to interested persons to make representations to the Minister of Regional Industrial Expansion with respect thereto; Therefore, Her Excellency the Governor General in Council, on the recommendation of the Minister of Regional Industrial Expansion, pursuant to subsection 19(1) of the Canada Post Corporation Act, is pleased hereby to approve the revocation of the Prohibited Mail Regulations, C.R.C., c. 1289, and to approve the annexed Regulations respecting non-mailable matter, made by the Canada Post Corporation, effective January 1, 1990. These Regulations may be cited as the Non-mailable Matter Regulations. In these Regulations, letter-post item has the same meaning as in the International Letter-post Items Regulations. (envoi de la poste aux lettres) For the purposes of the Canada Post Corporation Act and the regulations under that Act, the items set out in the schedule are non-mailable matter. Any non-mailable matter found in course of post, other than non-mailable matter that is seized under the Customs Act, shall be disposed of as follows: any non-mailable matter included in item 1 or 7 of the schedule shall be destroyed or disposed of in a manner that does not expose any person or property or the environment to danger; any non-mailable matter included in item 2 of the schedule shall be delivered to an association for the protection of animals or any other facility that shelters or looks after animals; any non-mailable matter included in item 3 of the schedule shall, where its outside cover bears a return address, be returned to the sender or, where its outside cover does not bear a return address, be destroyed; any non-mailable matter included in item 4 of the schedule shall be delivered to a police officer, a peace officer or the competent authority, as applicable; and any non-mailable matter included in item 5 or 8 of the schedule shall, where its outside cover bears a return address, be returned to the sender or, where its outside cover does not bear a return address, be disposed of in accordance with the Undeliverable and Redirected Mail Regulations. Where any non-mailable matter is returned to the Corporation by a customs officer, it shall be held by the Corporation for 30 days, or where legal proceedings in which the non-mailable matter may be required are commenced before and continued after the expiration of the 30 days referred to in paragraph (a), until the final disposition of those proceedings, and thereafter shall be disposed of in accordance with section 4. Where any non-mailable matter that contains an intoxicating beverage is returned to the Corporation by a customs officer, it shall be returned to the country of origin where the addressee so requests and pays the return postage therefor; or held for 30 days and thereafter destroyed, unless within that time the addressee requests that it be returned to the country of origin and pays the return postage therefor.
