Story from geocoder.ca:
This is the grist of the matter:
Since 2004 we have crowdsourced* the generation of the "Canadian Postal Code Geocoded Database."
When you make a query to geocoder containing for example this
information "1435 Prince of Wales, Ottawa, ON K2C 1N5", we then extract
the postal code "K2C 1N5" and insert it into the database that you may
download for free on this website.
This allows you to look up a postal code (eg K2C 1N5) on www.geocoder.ca, or www.openstreetmap.org or a number of other sites that use geocoder.ca data and technology.
Since we do not have a postal code dataset from the authority on postal
code assignments, namely "Canada Post", we derive and guess this
information sometimes with pretty good accuracy results.
Now "Canada Post" has sued "Geocoder.ca" in Federal Court, asking
"Geocoder.ca" to take this database down from this website, and also to
"pay Canada Post" damages on lost business the later has suffered by not
selling enough copies of their own postal code file (last time I checked at $5,000CAD a piece).
This brings us here. Having to face a crown corporation with deep
pockets in Federal Court, over something we have created but which they
Fighting for principle is expensive, and we will do it. Even against the
odds, namely the foremost law firm in the country for IP litigation,
hired by Canada Post to bring us down.
It will be easier with your help. If you are an entity or person who has
benefited from Geocoder.ca free or commercial products and services write your thoughts on Canada Post's desire to shut down this website.
