There are research agencies in Canada that develop drugs and other medications, they will need more funding because the current US is not going to see 2026. Or it will see 2026 but there will be a civil war either brewing or all out happening.
I do not think patents will really be a concern on things coming from the US, but there will be research done in Canada.
0% I am boycotting the US as much as I can and buying Canadian first, anywhere other than the states second, or if I cannot get the product elsewhere I do not need it.
