I don't normally agree with this government on public policy, but if they are proposing tax simplification, I am in full support.  I've been doing my own taxes since I was 17, and the form has gotten progressively more complicated.  And the last government made it longer still.  Enough, get rid of most of these tax deductions.
My suggestion to Mr. Morneau is that he focus on eliminating the charitable donation tax deduction.  Of all the deductions, this is the one that is the most abused by scammers, criminals, and salary-collecting executive directors.  People are happy to donate to charities with after-tax dollars, so let's stop helping the scammers in this sector.
