Do Canadian lenders oppose BRRRR?

[Noah Audette]

I am three houses into my Brrrr method, but am now "maxed" and "borrowed out" I've met with/spoken with over 30 brokers/lenders, and everyone is looking at my monthly income. All of my houses are 2% rule, fantastic cash flow, 100k + in the bank ready to go, no debt (but 660 credit score and building), and am told I cannot legally acquire anymore properties because of my personal income. I make 55k a year at my job. No one in USA is encountering this. Is BRRR possible in Canada?
