I'll answer the last question first.
I have not had a discussion with the Public Health Agency of Canada about the rationale for vaccine requirements—especially after some of us started questioning exactly what the requirements were.
I will say that many provinces recognized that proof of vaccination outside of special domains like health care and long-term care was unlikely to offer a significant benefit to the population to reduce transmission, and it was largely dropped. Many provinces started going through this in March and April as omicron started fading, recognizing again that the evidence behind a two-dose vaccine mandate or a single dose of Johnson & Johnson, which could have been a year or more ago, was that they likely had very little impact on pandemic transmission.
That was March and April of 2022. We're talking right now in September 2022 about finally dropping it at the airport to cross the border. There was a delay in recognizing that this was not an effective measure. Again, the impacts of it were felt across a number of different sectors.
