I want to begin by clarifying that most decisions to refuse requests are made by the corporation or its board of directors. Their mandate is to administer the fund. In most cases, refusals are simply due to the fact that people do not meet the minimum eligibility criteria. They sometimes have little knowledge when it comes to PPPs. They submit a project that does not necessarily fall in line with PPP requirements. It is also part of the corporation's mandate to educate various stakeholders on how PPPs work. Either a project is simply not a PPP, or it is not in a category of projects that are eligible for funding. The refusal may also be due to the fact that the project is far too large to be covered by the fund.
