Thank you again.
There is no data, and there won't be any for quite some time. In Quebec, the measure was introduced in the last budget, along with the ways and means. In Saskatchewan, the proposal for an innovation box was presented in the budget as a proposal, with the details to be worked out later. The government undertook an internal task force, which will be reporting on the details any time around now in Saskatchewan.
I would anticipate very modest results, because it is relevant only to provincial income taxes, which is a small portion of the overall tax bill that a corporation faces. Larger corporations and multi-jurisdictional or multi-national corporations tend not to pay much provincial income tax. Small businesses within a province tend to pay none at all. It would only be a small subset of businesses that would be able to avail themselves of the benefits of a provincial innovation box. In conjunction with a federal program designed similarly, the impact could be quite different.
