I'll start off with that.
On public health, if the system is meant to protect the safety of travellers and Canadians, it isn't so much that there's a problem with that objective; the question is whether the current process actually facilitates meeting that objective.
As Dr. Crowcroft suggested, I'm not sure we're the right people to speak to public danger, or placing excessive demand on the health care system. But when it comes to matters of public health, I think the question I was trying to raise was: does the current process and the current medical screening process actually address the objective of protecting public health? I suggest to you there are elements of it that do not.
