Someone has a lot of time on their hands, as evidenced by this recent YouTube entry - it presents every top of the hour GTA station identification (and some from Buffalo) ranging from AM 530 to FM 107.9 in excellent quality. Why someone would want to do this is another question, but at least they did it very well.
It takes more than 40 minutes to go through it all, although the visuals that accompany the video don't always match the place that's being highlighted. A small quibble in an unusual piece that took a lot of work to put together. (A hat tip to Canadian Radio News for the link.)

Well. that's one minute I'll never get back. That's as far as I got before ending it.

Yep, very long. But certainly thorough!
