Canada Post is telling Canadians Junk mail is good for you,

The national postal service has been sending out letters across the country to those with the audacity to post “no flyer” signs on their mailbox, telling the reader they are missing out on “being connected with your local community.”

Canada Post has mailed more than 900,000 of the letters in hopes the recipients might change their mind.
“Your address is part of Canada Posts’ Consumers’ Choice database as a result of having a ‘no flyer’ notice on your mailbox,” read the letter. “You are currently not receiving unaddressed mail delivered by Canada Post that your neighbours are receiving. This includes mail that can save you money and keep you connected with your local community.”

To receive unaddressed mail (i.e. junk mail), Canada Post asks recipients to sign up by sending an enclosed paid postage card and remove their no flyer notices from their mailboxes.

Canada Post spokesperson Anick Losier says the letters were intended to update its Consumer’s Choice program, saying the program has not kept pace with Canadians who have changed their addresses.

STOP unwanted waste delivered to your porch

How to stop unwanted waste delivered to your porch?
1. Call the Canada Post to request no more junk mail: 1-866-607-6301.
2. Adhere a “No Junk Mail” sign to your mailbox.
Stop unwanted newspapers by calling them directly. It’s a tedious job, but someone has to do it, and because many of these papers are opt-out, you are the only one who can take action.

How do I stop delivery of Admail items to my home or business?

To stop receiving unaddressed advertisements such as coupons, flyers and newspapers, free magazines, catalogues, and municipal service notices (e.g. schedule of snow removal, changes in garbage pickup, etc.), place a note in or on your mailbox stating that you do not wish to receive Unaddressed Admail™.
The only unaddressed materials that we will continue to deliver are some community newspapers, as well as mailings from the House of Commons, provincial chief electoral officers, municipal electoral offices and Elections Canada.
We are required by law to deliver any mail that bears your address (including some advertising material). Please note that since Canada Post is only one of many distributors of unaddressed materials, you may continue to receive these materials from other distributors.
