I do not know what regulations Canada has, but US postal regulations require a chick to be processed and in the mail 24 hours after hatch. There has to be a reasonable expectation that the chick will be delivered within 48 hours after entering the mailing system. That is a total of 72 hours. A healthy chick that absorbs the yolk can go that 72 hours without eating or drinking and still be in great shape. It lives off of the yolk for food and water. For the health and safety of the chicks, you do not have to remove them from the incubator for at least 72 hours. If the hatch is over earlier than that, you can remove them. They probably won't eat or drink a lot if you take them out early, but some will. It will not hurt them to eat or drink earlier, it's just that they don't have to. The incubator is a safe temperature for them.
It is possible to shrink wrap a chick that has not hatched by opening the incubator before it hatched, especially if it has pipped. The reason you raise the humidity for hatch is to help reduce the chance of shrink wrap. Since there is a risk I try to avoid letting the moisture out by opening the incubator. I personally don't see any reason to take unnecessary risks with hatching chicks. But, even if you open the incubator at a bad time you usually do not see any shrink wrap. The actual risk is fairly low. If I have an emergency in the incubator I'll open it and take care of the problem. One time, half of an eggshell from a chick that had hatched cupped around an unhatched egg. That would have made it really hard for a chick to pip or zip so I opened the incubator and took care of the problem.
From what you described I do not see that you have any kind of emergency. I'd wait.
