Two words: Venture Capital.

Most Canadian employers are not VC-funded, the pay they can offer has to be in line with general rules of finance: spend less than you make.

Compare that to something like Uber where the company makes 9-figure losses, and yet can afford to pay high six-figure salaries. Someone has to make up the difference, and as is often the case with tech companies, it'll be venture capital firms.
