I'll give you a few and I'll ask my colleague Patricia Kosseim to complete the list.
We say “including” because this kind of discretion exists under PIPEDA. We can manage our work volume, essentially, by refusing to handle certain complaints on various grounds, including if a complaint is frivolous or vexatious. There are, however, other grounds in PIPEDA. For instance, is there another effective remedy available to the individual, other than to make a complaint to the Privacy Commissioner? Is the commissioner seized of another complaint that raises the same issue? In order to be efficient, you look at one complaint, not a number of complaints. These are two of the grounds in PIPEDA.
Madam Kosseim will complete the list.
