I believe this shit, or the cover up for it was still going on even fairly recently, so acting like this was ancient history is nonsense. Obviously they won't put out an arrest warrant for the Pope, but they should be demanding all records pertaining to this stuff and be investigating those involved, and be talking about revoking whatever their special religious status (tax exemptions, etc) is in Canada if they don't. Until these organizations face real repercussions for this behavior it won't change.
And yes, Canada needs to really own their role in this as well. Unfortunately this will probably boil down to nothing as the two sides just blame the other for everything and then conservatives will get in lead roles at one or both and kill anything being done about it.
