It would be very much a case-by-case situation. For example, if you are receiving advice in relation to measures to be taken in the aftermath of the Lac-Mégantic incident, and there are recommendations being made and advice being given to a minister or to senior officials, then you would have to assess those particular records and that particular advice to see if there would be harm in disclosing that information at that time, as well as whether there would be an overriding public interest in the disclosure of that information, at that time.
It is very case-specific.
