"giving tax advantages to a select few. We don't think that's fair."

And giving tax breaks to a large number of people who can use it because they have money is unfair, massively unfair. And one form of tax breaks is a direct attack on democracy.

First, tax breaks are unfair because those without tax breaks or more important, those who do not have money to use tax breaks, pay additional tax to make up for the lost revenue. There are RRSPs, TFSAs and countless financial instruments including "charities". 

So called charities are restricted in their political activity. They cannot lobby government for fear of losing their tax break. So government can pass odious legislation and a large number of people cannot (well will not) lobby against it. 

Now incorporation is exposed. Another tax break.

All tax breaks should disappear. A level tax playing field.
