7.7 MPAC Lists and Jury Selection Juries are selected in Ontario through a process described in the Juries Act. Enumeration lists are obtained from the Municipal Property Assessment Corporation (MPAC). These lists are updated only once every four years, and persons at the households contacted by MPAC provide their date of birth and citizenship information. As a result, MPAC lists do not reflect changes in personal circumstances within that time period. The random selection process for juries proceeds as follows: a request for jury selection is made and MPAC selects persons for each district who have indicated by the returns (enumeration form) that they are over 18 years of age and are Canadian citizens. Questionnaires are subsequently mailed out to the randomly selected indi- viduals to determine whether they may be considered as potential jurors. In what ways might this list not cover certain sectors of the population adequately?
