These are just my thoughts on that. Firstly, at the initial outbreak of this pandemic, there was not a lot of information, unfortunately. We're learning as we go along, quite frankly. Where we are now with the knowledge of COVID-19, its pathogenesis, essentially its incubation period, the fact that there is a percentage of asymptomatic and presymptomatic carriers and the potential spread are some things that we didn't know early on in January and February.
Having said that, the work for opening up the borders, that's not done by me alone. I would certainly not make that determination. That would be done in consultation. That would be driven by government, participating with all the stakeholders, including the aviation industry and Canadians in general, on determining what those factors are that would minimize the risk as much as possible.
I know that it's not going to be zero, but we need to minimize the risk as much as possible, be that setting up certain measures for the other country in terms of its case rate, its positive infection rate, the number of tests they do per capita, etc. These factors would really have to be worked on and determined, but that would be in collaboration with all stakeholders, including government, the public and the aviation sector.
