No, it is not true that investing $100,000 CAD in a government project would automatically grant someone permanent residency (PR) in Canada.
While there are several Canadian immigration programs that allow individuals to obtain PR through investment, such as the Quebec Immigrant Investor Program and the Federal Start-Up Visa Program, simply investing in a government project does not guarantee PR status.
Each immigration program has specific eligibility criteria, and applicants must meet these criteria in order to be considered for PR. Additionally, the Canadian government carefully reviews all applications to ensure that they meet the necessary requirements and that the investment is legitimate and beneficial to the Canadian economy.
