I'll make a couple of points. First of all, it's worth underlining that the mobility of Canadian workers has improved quite markedly over the last decade. We have some research done at the Bank of Canada that shows this, and we can share it with the committee. This has noticeably improved the efficiency of our labour markets. While there are still issues of matching workers with jobs and of skill gaps, the efficiency of the labour market is better than it was.
In other words, for every level there's a locus between unemployment and vacancies, and that is shifting to the origin, so that there are fewer unmatched jobs. A big part of this is due to improved mobility.
There are other elements to that matching. We've already talked about skills. That is an important element: making sure that the workers have the skills the employers need.
In terms of further improving mobility, there has been some progress, and there is room for more progress around accreditation. It's a case of having a labour market across Canada, in which particular workers in trades can move seamlessly across provincial boundaries—
