Ann: Proposal to Voluntarily Delist from ASX, page-26

If they delist then there is a significant chance they won't relist in Canada or Australia. With the onus on the shareholder to make their own sale arrangements through a broker, there is a very real chance that nobody will ever be able to offload their shares ever again. This would make CHP an unclaimable loss.
Not only are they running the company into the ground, but they're taking everyone else with them with no life rafts.
