That is right. The law in Canada explicitly excludes taxis from the $30k exemption, and taxis must collect gst/hst on all rides, regardless of how much the taxi's sales were in a year. Uber was exploiting this rule by saying their services weren't 'taxis', and each driver was independent, and therefor that rule didn't apply to them. It's a sneaky way to charge most people 5-15% less than their taxi competition.
