However, I think the issue, which the Democrats have raised as well, and so have New Democrats here in Canada, is the fact that the enforceability of side agreements, the eligibility of those, is quite weak. We saw that in the original NAFTA, that when things are in side agreements, we haven't been able to enforce those provisions. That's the fear, that if we add on, after the fact, in side agreements, we won't be able to actually enforce them at all.
