I have looked it up, Andy.  The total contribution by Ontarians to federal coffers has always been, and continues to be, the biggest portion of federal revenues.

And, let's be clear, _Alberta_ (or Ontario, or BC) does not contribute a cent to equalization.  _Albertans_, like all Canadian taxpayers, do.

And even recently, while equalization payments went to the Government of Ontario, _Ontarians_ continued to be net contributors to federal revenues.

I'm surprised that you haven't come across these basic facts in your research on equalization, Andy.  Robin Boadway's articles on fiscal federalism might be a good place to start in adding to your reading.
