2. Cut out junk mail: Canada Post will not deliver unaddressed junk mail to homes which place a sign inside their mailbox saying "no junk mail", "no flyers" or something along those lines. Unfortunately, Canada Post is still obliged to deliver addressed junk mail. However, you can register online with the Canadian Marketing Association's Do Not Contact List (again, it takes about 30 seconds) and CMA members will stop sending you their junk.
3. Get rid of bulky phonebooks: Who needs them when a phone number is just a click away? Save a tree or two and a trip to the recycling bin by opting out of phone book delivery, again through a handy online form from the Yellow Pages Group.
While these tips won't completely banish all unwanted advertising, they should significantly reduce the amount which finds its way into your home. Not bad for five minutes, right?
