I can see income taxes being increasingly replaced by transaction taxes, are you listening President Trump? I can see some fiddling here at home with capital gains and feel good stuff in the budget but it will be financed with increasing the GST in steps to at least 7%.
What might kill our economy if it exists across the country is the way in which Calgary calculates it assessment/mill rate. It is called "revenue neutral" which means no attention is paid to the drop in assessed values (6 B last year, and that is probably less than actual since it is a lagging indicator). Instead the assessments are increased on other classes of property and the mill rate edged up to meet revenue targets,all while maintaining various reserve funds of about 2 B.
This means that the City "planners' and spenders " will never  address reality of the real world. They do "comparisons" to other jurisdictions with the same type of tax regime and declare success.  How about bringing in a zero base increase??????
