What I think people in the thread are getting right is that CP is an upscale brand and as such a notch below upper-upscale brands such as Marriott or Hilton.
But I think the defining feature of CP is that each and every one has facilities for conferences and meetings. The brand standard requires it not just in city and airport but also in resort locations. Quality of CP's is a bit above HI, sure (slightly larger rooms, higher-quality furniture on average, better front desk service, valet service). But the main difference is that HI is supposed to be more "fun" whereas CP is a bit more "serious". They want to appeal to the business traveller and to firms/institutions looking to host a conference. So they have decent meeting rooms as well as usually a more usable desk than an HI.
But they're not trying to deliver an experience that's upper-upscale or luxury. No marble bathrooms, no concierge service on the level of a Hyatt, dining options that are usually a notch below those of a Hilton or Radisson Blu, etc.
