Most of the companies in my industry are very secretive about their competitive advantages and the jobs they have available and those people they've lost or couldn't bring in.
Anecdotally I hear this all the time that companies are on the verge of losing the opportunity to bring in a worker for a position because they simply can't get the labour market impact assessment through, that there are jobs that are absolutely necessary for a project to happen and they are unable to bring those people in because we're unable to find them here in Canada.
In terms of giving you statistics I don't have them.
