Try to block all your junk mail! Call the Post Office. They will refer you to some third party service that will beg on your behalf to get your name off the mailing lists... The Unions fight but they give you an ineffective out, more junk mail means more jobs.. it also means that whole Canadian Forests are cut down every year and thrown away but the Union doesn't give a rat's ass about that...
As an aside, here is how to stop your junk mail: take all the items with prepaid return envelopes and cut them up, leave in the part with your name and address, put them in the envelopes randomly, send them back on the issuer's dime... your junk mail will be reduced by 95% overnight because the junk mailers don't want you messing with them like that... if you have a relative with dementia do that, they won't buy a hundred magazine subscriptions so they can win the big prize...
