"And also in 2013 the richest 1% in Canada own about 50% of all wealth and they pay roughly 20% of all taxes."

If by richest you mean by wealth, these 1% don't pay any income taxes.  Canada don't tax people based on assets ( apart from property tax).

If by richest you mean by income, the richest make 10% of all total income but pay 20% of all income taxes. 

Got the difference?
