Some of the "look over there" arguments against these new measures are getting out of hand.  I read another column about the problem of owners having to pay double CPP as an argument against the new measures.   It's a wash between whether owners take a salary or take a dividend or a combination of both, as far as how much tax is paid on it, either by the individual or by the company.  So, if you want to pay the employee portion only of CPP, take a salary and have the company deduct the employer's portion of CPP.  That reduces the company's taxable income. There needs to be mental separation between the company and the individual.  You are not legally your company.
In the end, the only two sure things will always be death and taxes, and only one of those things can be made more fair.
But I expect the government will cave or at least compromise and decrease the proposed tax on passive income.
