That's a great question.
It's hard to predict. It's virtually impossible to say that a national rollout would be x simply because it depends on a whole number of factors. The first is what we learn from the pilots. The second is the decisions by both the federal and provincial governments on where to go with these kinds of issues. The third would be where our international partners go, because it looks like we're heading to a system where there will be some kind of recognition. If the work that's under way at ICAO that Canada is involved with pans out, there would be some sort of rules of the road or rules of the air, if you will, with respect to testing for international flights.
When we look at how to do all that, you come back to first principles and how you enable Canadians to travel by air whether domestically or internationally so that they are safe, given the COVID threat. Testing is part of that, but a lot of things go into that. Among them are the cleaning protocols, the mask wearing. In Canada, in mid-April we required passengers to wear masks on planes. It turns out that if the cleaning protocols of the airlines, the physics of how air moves within a plane and strict protocols like masking all come together, it almost counterintuitively results in air travel being a reasonably low-risk activity for passengers.
We've worked really closely with the industry. There's real leadership in the industry on the part of the airlines. The airports are under extreme financial and economic stress, but they're committed to doing whatever it takes to keep their clients safe. Working with them we've been able to put together the flight plan. Canada has something called the flight plan, which is a national plan for COVID-safe air travel. We see testing fitting into that, but I think the question is making it work from a system perspective. There is progress to make. I think the pathway will depend on some government decisions, some international partner decisions, but also really close collaboration with the industry operators.
