I would suggest that we look at timing and the validity of the medical examination. Right now it's valid for a year. If we're concerned about health during travel and the journey to Canada, it makes more sense to have that medical examination closer to the moment of travel.
The other thing is that there are elements of the medical screening process that are onerous, heavy, and very paper-intensive for local public health, and for minimal benefit. That is why I would suggest that we review the processes currently in place and determine whether, in fact, they serve the objectives of the current act and its regulations.
