I certainly can.
Your colleague beside you asked the same question. The decision to no longer rely on the Access Copyright tariff but other sources of copyright clearance has nothing to do with the adding of education to the list of purposes for which fair dealing can be engaged in. That decision to not pay the tariff is based on the Supreme Court of Canada decision only. If the Supreme Court of Canada had issued a decision that was different from the one it did, there would have been no opting out of the tariff system.
Prior to that decision, it was not clear whether teachers could make a copy of a short excerpt—“a little bit” was the term being used—for each of the students in their class. It's called “multiple copies for classroom use”. You have a classroom with 30 students in it. You want a copy of a newspaper article. Can the teacher make a copy for each student in the class? It was thought, up until that Supreme Court decision, that you could only make one copy, that making multiple copies for a class of students was not allowed. That decision made a profound change on the law on fair dealing, but had nothing to do with adding education as a fair dealing purpose. The Supreme Court decision happened in July, and the opt-out was the following January 1.
