I want to come back to the history perhaps, from the CRA perspective.
It wasn't necessarily a refusal. We, like many tax jurisdictions, have concern over the accuracy and the difficulty with measuring a tax gap. In terms of co-operation with parliamentary officers, we had privacy concerns and legal advice that prevented us from co-operating to the full extent that they might have desired.
The minister is correct, though. Last June, we did release information on the GST. This June, instead of just pointing out how complicated it is, we've partnered with the Canadian Tax Foundation to hold an international summit on tax gap. Through the Canadian Tax Foundation, we're bringing in international experts, inviting stakeholders, and we're going to explore these methodological difficulties with measuring the tax gap. We're actually seeking to engage academics, statisticians, and others to get past “it's difficult to measure the tax gap” and develop actual strategies that will bring us, I think, to what we all want, which is a fair tax regime.
