I'll start off once again. Thank you.
We have a very similar process to that laid out by my colleague Mr. Fenrick. We receive our data from four main sources. We're very up front about all of these.
The primary one we don't purchase. It's provided to us as part of the electors list from Elections Canada. That is 90% of our data. It is the information about who is an eligible voter. That makes up the lion's share of what we have in our system.
We do purchase data from two sources. One is InfoCanada. It's basically the white pages. We buy the phone book, so we get some phone numbers to match up with those constituents who we get from the list of electors. The second one we purchase from is Canada Post's change of address list, so that our lists are as up-to-date as possible, because that is issued more frequently than the list of electors.
