If it were to become abundantly clear to the Canada Revenue Agency that the HRTC was not going to be passed.... Currently, Parliament has agreed in principle to the ways and means motion that was tabled with the budget, and the CRA will continue administering it on that basis until such time as it becomes clear that Parliament will not pass it.
So, for example, if Parliament were to defeat this bill, then the CRA would have to suspend its administration of the measure.
