I want to start by saying that every country is different—given their domestic capacity, for example—and therefore the negotiations with countries and the resulting contracts are not identical.
In terms of Canada's bilateral contracts with vaccine producers, there are a number of clauses that we as the Government of Canada, as one of two contracting parties, need to respect as a matter of law. More importantly, perhaps, we don't want to put our vaccine procurements at risk. We all need vaccines. If we were to disclose these contracts, we would risk receiving those vaccines, because we would be in a potential breach of contract.
