I am not aware of any studies that we have that quantify those measures right now. I don't think I have anything I can provide. I can check when I get back to see if anything has been done.
The only thing I can maybe point to is a recent survey done by Statistics Canada that outlined some of the key local-level impediments to supply. It doesn't quantify in terms of additional cost, but it identifies, at the local level, some of the impediments that have the biggest impact on the supply response.
