Thanks for the question, Madam Chair.
In terms of regulatory co-operation and working with the provinces and territories, it won't surprise anybody if I say “it depends”. It depends on the complexity of the issue, the complexity of the regulatory framework and potentially how divergent the perspectives are between the provinces and territories.
With the building code discussions, momentum had already been built, and they were probably a source of frustration, so those negotiations I believe took a little less than a year. Then the real heavy work begins in terms of truly harmonizing the regulations going forward, and that's the phase of work they're in now.
If I give another example, in terms of the negotiations with the EU over the sunblock issue, again, there was probably a lot of groundwork behind the scenes before we even got involved from a true alignment formalization perspective, but again it's about 12 to 18 months, and then the systems are in place almost immediately.
