No, I don't.
I wouldn't characterize my analysis as critical. I think I'd counsel caution that a one-size-fits-all national approach to this might end up costing everyone more money instead of maximizing benefits. So a province-by-province approach is certainly something we would advocate, primarily because procurement regulation and oversight falls within provincial jurisdiction.
I think the example you bring up in Nova Scotia is a perfect example of our understanding. It was the province alongside the federal government that was mainly interested in using this agreement to continue its own efforts to do exactly what it was doing. So a province-by-province, territory-by-territory approach is going to allow the kind of flexibility and context sensitivity to ensure that the new regulations are as streamlined as possible.
All I'm counselling is caution that a one-size-fits-all regulation at the national level might end up costing more than it needs to.
