As a physicist, I can't offer any economic models that could be used for that purpose. However, just making sure that the decision is always made in Canada is one way of ensuring greater benefits domestically. As everyone knows, when a company's headquarters are not in Canada, the benefits for Canada, as far as knowledge and research go, are minimal. It is imperative to develop a domestic company through various means.
As a physicist and an academic, I come at the issue from a broader standpoint, so I don't have any concrete suggestions to offer.
