(The following is directed mostly at non-Canadians.)
Like most news channels, CBC Radio One claims to be "the source Canadians trust," but unlike almost all the rest, it can make the claim and be taken seriously. The round the clock coverage of the invasion of Iraq has (so far) been critical, sane, civil and balanced, constantly getting a different and relevant perspective on events.
In a world where Fox News and CNN can be referred to as "journalism" without everyone within earshot cracking up at the mere suggestion, I must say my standards have been lowered considerably. But still, if you're looking for a news source that isn't a bombastic, self-righteous reprocessor of official propaganda, I recommend tuning in. Did I mention there are no ads?
