*******************************************************************************
In response to your request, here is the all-Canada 2001 postal code population 
weight file (wcf01da.can) together with its record layout (wcf01da.doc). 

For each 2001 postal code, this file shows the percentage the total population 
served by that postal code which is found in each 2001 dissemination area (DA). 
Most urban postal codes only serve 1 DA (in which case the weight is 100, and 
there is only one record on the file for that postal code), while most rural 
postal codes serve multiple DAs (in which case there will be multiple records 
for that postal code, and the weights across the various DAs served by that 
postal code will sum to approximately 100). Note that the populations were 
random rounded before calculation of the percentage weights, so the sum of 
weights for any particular postal code may not equal precisely 100. A weight of 
zero means that less than 0.5% of the postal code's population  was found in 
that particular DA (after random rounding).

This file was produced from 2001 census postal code and population data. It is 
conceptually similar to the 1996 postal code population weight file, except that 
it shows the percentage distribution of the population of each postal code 
across 2001 DAs rather than across 1996 enumeration areas (EAs). Note that the 
service areas of postal codes shown on this file are not necessarily the same as 
those implied by the Postal Code Conversion File (PCCF). 

The 2001 postal code population weight file was produced not as a stand-alone 
product, but rather to serve as input for PCCF+ Version 4, which uses a 
relatively small subset of the total records (for delivery mode types which 
typically span multiple dissemination areas).
