Delta Hotel Canada
OK, I have mostly been a lurker in the shadows, but today I'll comment.
I use Delta Hotels when I can, and have found them to be great. I had a bad service experience once and complained at the front desk; they admitted the error and since then have taken care of me exceptionally well at that hotel (14 stays later).
The hotels are in reasonable condition, the service is pretty good, and the staff are nice/heplful. The program is a good one and I intend to stick with it.
One recomendation: if you have to stay in the Sydney NS hotel, then book ahead as it can often fill up.
