McMaster has been involved in the Pearson study; that's travellers coming off Air Canada flights voluntarily at Pearson airport. The Calgary pilot is being run in that sense by the health authorities provincially.
Part of the McMaster study was point-of-entry testing and then day seven testing. It doesn't change quarantine; it's essentially a data-finding expedition in that sense. There is no public health advice tied to it.
Calgary is different in the sense that they're using day two testing to release people from quarantine and then using a day seven test as a follow-up for those people. They're contracted to do the test, day two and day seven, but they're using the day two rapid test to take people out of quarantine and then using the fail-safe of day seven, telling those people to be very careful about their interactions. They are not necessarily imposing a strict quarantine, just masking and minimizing interactions, not going to public places, and not seeing vulnerable individuals. Day seven would be getting a secondary test and if the secondary test is negative, then they can go about their business as normal.
I have to apologize. I don't know what's going on in Montreal. You're probably the first one to mention it to me.
