Gino's case against us has been dismissed. Scientists cannot effectively sue other scientists for exposing fraud/errors in their work. Those who work to correct the scientific record can sleep better tonight. Those who don’t want it corrected, well, I don’t care how they sleep.

Interprovincial trade barriers costs us up to 7% of the national GDP, in 2024, that amounts to $90 billion. Harmonizing and reducing regulation would boost productivity and help an economy in need. What are we waiting for? theglobeandmail.com/opinion/editor…

Another thing to add to this discussion of "negative probabilities" is that they have nothing to do with negative quasi-probability objects in quantum physics. They are just a consequence of allowing for arbitrage in your model. You don't want to price options with that model.

The whole narrative that Trudeau is spinning is full of half-truths and half-lies: yes, universities have increased international student enrolment over the last decade. But this happened with the explicit encouragement of the federal, Trudeau government. There was a federal

.Chrystia Freeland is absolutely correct that the HST holiday and $250 checks are political gimmicks and very bad economics. It is very comforting to see a politician make a stand on principle especially for something likely to be politically unpopular.

Decades ago, the US and Canada slapped tariffs on Korean and Japanese cars. The result? Stagnation in American auto innovation, while creativity surged abroad. We all know what followed—better cars from elsewhere. History’s repeating itself now. Protectionism doesn’t work—it just
