Isn't there a difference in range for HD radio compared to the traditional FM station, of like a fifth of the coverage?

There had been an FCC-mandated limitation to FM HD Radio that limited the power to a % of the station's conventional power, but this amount has recently been upped: FCC Authorizes FM HD Radio Power Upgrade in U.S.

I've found on both of my home HD Radio tuners that during bad weather the SeaTac stations' digital streams will go out of service occasionally while the conventional FM carriers are still doing fine or are maybe fluttering a bit.

In my vehicle it was not common to get the digital streams up here since the conventional FM signals from SeaTac are weak anyways.

I think its 1% the ERP of the FM carrier and the FCC has allowed boost up to 10% if the station will not create interference.

Almost. :)

1% originally, then a station can go to 4 or 6% without approval if I remember correctly. 10% does need FCC approval and proof of non-interference.

What I would like to see is a completely digital test of HD Radio and how that impacts adjacent and second adjacent interference plots. I mean, if we're going to make things more efficient, lets go all the way and do it right. Besides, it would be interesting to see the parallels between IBOC transmissions and DTV with respect to distance and power used.

So odds are in Toronto, the Buffalo HD can't be picked up then cause its to far away (?). Being down in Windsor now I am sure I'd get the Detroit ones though.

Any word if/when this comes down the pipe in Canada?

You would definitely get all the Detroit area FM HD Radio stations in Windsor. :) The sound quality is wonderful, and the selection of subchannels on some of those stations is probably good too.
