The WTO operates by consensus, so I think it would be difficult to imagine how it would be possible.
I would also say, however, that for many members, including Canada, intellectual property issues around COVID-19 are only one aspect of the issue. There is a range of other issues that can be discussed at the WTO, including trade facilitation, including the removal of export restrictions—things that would encourage the supply of vaccines and inputs to those vaccines.
There is thus a range of policy options and legal options available to the WTO, and consensus could be reached on other aspects.
Canada is working hard—for example, in the Ottawa Group—to come forward with proposals that would address some of these other issues.
