Postal code and route mapping in Canada is a little different from that of the States. In fact, they are undergoing a change in the way they handle their street addresses. One example of this, is in the Burlington area. Most of this area is a part of Rural Route #2 Milton, and Rural Route #6 Milton, and then still Rural Route #3 Campbellville for their mail delivery.
But, while this is true, these areas all still have an address that is a Burlington street address. This fact has caused many to suffer having their mail incorrectly reflect them living in the wrong location. It has made delivery very difficult and confusing. It has also been the cause of loss of access to emergency services. So they decided to change the postal identifier to Burlington so the rural areas will get the same type of mail delivery as everyone else in Burlington.
They began the process of fixing this problem in 2005. Local counselors and Parliament members met with people from the Canada Post and work on a solution to this confusing problem. They had to create brand new postal codes for the rural areas within the Burlington system. Their proposal for their solution did not get approved until 2009.
