I see your question, at its core, as this: What would it look like if interprovincial trade were more fluid at higher volumes and with less regulatory friction?
I think it would allow Canada's more innovative entrepreneurs, those who are more careful about their costs and so on, to get those markets internally. In that way, it would have this effect of competition bringing productivity and better choice for consumers. It would essentially give better integration of the economy overall.
As for what that would look like in terms of economic variables so that we could track progress, I think that's something we could certainly do separately, or the government could establish metrics that it could commit to follow in terms of how it plans to target that aspect of what success looks like in interprovincial trade. Whether that's the government bringing that forward through its economic budget, updates, departmental plans and departmental results or whether that's the committee asking the parliamentary budget office to do that within our work plan, it's the type of thing you can put numbers to.
