a private post-secondary institution that operates under the same rules and regulations as a public institution, and receives at least 50 percent of its financing for its overall operations from government grants (currently, only private college-level educational institutions in Quebec qualify) or
a Canadian private institution authorized by provincial statute to confer degrees
