Cool. I work in the Waterloo Region, but will check that out when I drive back home to the GTA this evening. I seem to recall CHFI (98.1) trying HD out back in the '90's but then abandoning it.
I think you're confusing HD Radio and RDS data displays.
HD Radio is digital broadcast radio, specs adopted by the FCC in 2002 (and I have no idea if the CRTC ever adopted it or any alternate standard). Its been optional on some cars for ~5-6 years, and only now starting to become a bit more common...
RDS is an add-on to "regular" FM analog radio signals that gives info avail for display on the car radio (most commonly track titles). RDS was first introduced in Europe in the 80s, and made its way to North America in the 90s, although didn't become common until the 2000s (I had a 2001 BMW that could display it...)...
