Office of the Information Commissioner of Canada
This section, containing information previously published as “The Grids,” is a compilation of information designed to assist investigators in pursuing their investigations into various types of complaints.
The ATIA interpretations provided below are not guidelines, policies or dictates; they are explanations, primarily for investigations into the usage of the various exemption provision of the Act. They include discussions of the legislative provisions, judicial decisions made on those provisions and the logic of the exemptions.
They have been prepared over the years of the Office’s existence to help with the interpretation of the law involved in our investigations. Each one also provides suggested lines of questioning, to assist the investigator in fact-finding and in making recommendations for the resolution of the complaint.
