Or, perhaps Marco opened a new program without thinking through how it was going to be implemented and left Fraser holding the bag. Or, perhaps no one at IRCC anticipated Hong Kong, Syria, Covid, Afghan, & Ukraine all piling into each other. Or, perhaps all of the above and more.
Some of the latest MP chatter I've read seems to be leading to a possible recommendation that IRCC should have a dedicated 'emergency' line (because with climate change, for example, emergencies will be more common) so that 'regular' processing lines do not have to stop & shift what they are doing. That won't help us now, but it seems logical going forward.
