1.  Cut spending in a meaningful way. 
2. If you are going to fiddle with capital gains do something useful like vary the inclusion rate to allow for time factors.  If a stock or a house flip doubles in a year,  tax it a higher rate than farms or buildings or long term holds and after 10 years holding add in the inflation rate to the original cost.  As it is now capital gains are a tax on inflation after long holding periods.
3. Dividends are taxed at various rates depending on other income sources.   For retirees they might be the only income they have outside of CPP and OAS and occasional capital gains. 
4. And if your goal is fairness single people are already getting the short end of the stick for paying all the bills on one income. The immediate personal deduction should be increased for single people. 
5. How about raising the GST? It was bad idea according to the Liberals when Harper lowered it to 5%!!! they have been busy reversing everything else.........
