"Specifically I asked why the AGM was cancelled, although I don't expect them to provide an answer aside from ''we can't say''...."

Asked and answered.
"....and if notification for a rescheduled meeting would be announced with a PR or another SEDAR filing. I also asked why they didn't issue a PR with respect to the cancellation."
Because it's neither necessary nor required.
