You did, sort of. If there were 100 masks received, then 80 masks would be distributed across the country to the provinces and territories, depending on their population. If they had a very small population, they might get five masks. If they had a very large population, they might get more. Then 20 of those masks would be stored in the national emergency stockpile, against the potential of an outbreak in another part of the country.
