I don’t know any doctor or high earning professional that makes millions of dollars per year. You’re still thinking about the wrong bracket. We’re talking about the mega wealthy, hundreds of millions to billions in net worth. Also, no, the effective tax rate never actually decreases in Canada. You get taxed at higher percentages the more money you make. Someone making $750k a year gets taxed at a higher rate, both marginally and effectively, than someone making $50k. You’re assuming that all of this extra money is just coming from capital gains. It’s not.
