Not being rude, just passing along some info for educational purposes. It is actually against the law to use the word ''''purebred'''' or the words ''''pure breed'''' unless a dog or puppy is registered with the CKC or AKC. And it is also illegal to charge more for a puppy that is registered vs one that is not: if a breeder is doing this, they need to be reported to the CKC. $900 is actually pretty reasonable for a CKC registered dog.
Edited to add: Another source of finding a pup is a breed club. There is a Chihuahua Club of Canada - they can probably point you in the direction of a reputable breeder.
