What are the risks of applying for Canadian investment immigration?

There are several types of Canadian investment immigrants.

There is no risk in moving to Quebec. You can get permanent resident status in one step. You won't make money until the immigration application is passed. You can invest 800,000 Canadian dollars in the designated fund and return it to your capital without interest after five years. The price is 800,000 Canadian dollars in interest for five years.

It is risky for other provinces to nominate investment immigrants, because the money is invested in enterprises, and applicants can only get temporary status first. The invested enterprise must create a certain number of employment opportunities, and the enterprise must survive and meet certain conditions before it can become a formal permanent resident, otherwise it will draw water with a sieve.
