Can the CBC be actually correct?

Toronto held a gay pride parade a few weeks ago in its downtown core. The Toronto Sun, CityPulse *news* and 680 *news* all reported that crowd estimates stood at over 1 million people. Every year that I can remember the major *news* organizations have reported crowd estimates of over 1 million.

Why then did the CBC and gay pride parade organizers estimate the crowd to be only 150,000?

Who's right?

I'm just curious, not bi-curious, just curious.
