All or almost all proposed measures as far as I know regulations for PSB (personal services business) exist now. PSB should not make profit and then pay dividends. If somebody has corporation and make income by giving speeches salary should be paid and reasonable expenses not dividends! Small business is enough challenging, if you are not well connected with government(s) , so CRA regulations with 100 shades of gray definitions  just add final straw to break camel back.
