Canadian Politics Today

That depends on what they're saying. If they're simply stating what the deficit was from year to year, or how much spending has grown then I don't really see how they could be wrong aside from outright lying. But their bias in all things is fairly clear. They were founded by social workers, after all, and are ever eager for more government spending and more taxes. At least the Fraser Institute was founded by an economist.
