December 2011: Canada Post, which owns the copyright to Canadian postal codes, requested that we remove the postal code listing from our site. We're very sorry for the inconvenience.
We have included a single postal code:
Below are more of the post codes for Connaught, Ontario but the numbers have been replaced with "#" in the second part of each postal code.
Be aware that we have listed only a single complete postal code for
Connaught, Ontario (ON)
due to the request from Canada Post. You may search for full list of postal codes for
at Canada Post.
Our full U.S. zip codes and Australian post codes are still available.

Why is zip code data on an environmental science site?
In 2002 I was working on a project that correlated pollution and income for postal codes across the United States and Canada. While the Canadian effort did not work out so well, visitors told me the data files were very useful so I left them on the site and now update the postal information on a periodic basis even though the focus of the site is conservation.
