Investor visas (aka Golden Visa) aren't really a loophole, they're quite intentionally designed to bring money into a country and provide employment for existing citizens.
Nope, as part of the golden visa, he would've paid an immigration attorney to set up a Canadian company, shove some money into it and hire the minimum amount of employees. This is unrelated to the coffee business and doesn't have to be profitable, it's merely a requirement to gain residency.
After 6 years of residency, he can then apply for citizenship.
