Something to consider from a CKC breeder are references, show records, community participation and health guarantees. We know someone whose puppy, unfortunately, had to be put down due to serious health complications. The breeder was willing to provide a new puppy at no cost using two different parents ($3,000 value). Additionally, when we started looking for Westies, we ended up finding out that a lot of people we met at dog parks or friends of friends all referenced back to specific breeders -- they were popular breeders who provided healthy, long-living dogs. There may be backyard breeders who do it routinely but CKC breeders are certainly much easier to inquire about.
That said, we went with a backyard breeder who ended up being wonderful. It felt like a huge gamble to me at the beginning, but in the end we didn't have a choice when it came to using a breeder. My frustration with every single breeder in western Canada was due to ambiguous waitlist positioning (are we 3rd or 30th? No one would say) and frankly 80% of them didn't return emails or voicemails. I'm not sure what it is about dog breeder websites but they all look like they were made using GeoCities from 1994!
To your specific breed, I inquired with someone on the pathway about their Havanese and I'm pretty certain they mentioned a great breeder in Camrose. Google returns this one but I don't know if it would truly be the same one:
