When it comes to cross-tabulations, we've done cross-tabulations of counts. We don't have access to census data with names on it, so we haven't done those kinds of cross-tabulations.
In maintaining the national register of electors, we measure the quality of the list by comparing it to those census numbers. We look at the census counts and ask how many people should be Canadian citizens and of voting age in your riding and compare that to how many we've got. Then we publish those quality indicators with the preliminary list of electors at the start of an election, and every candidate should be getting a copy of those numbers.
