With about 45 seconds left in my time, I'd like to ask a question. Anybody can answer this. It is regarding the requirements for trucking.
At the outset of the pandemic, our borders were quite open. We definitely suggested that truckers should be vaccinated, but we left the borders open so that truckers could move back and forth.
However, those guidelines have changed. Can the minister or Dr. Tam give us an idea of why we have changed those guidelines?
