Is he CKC as in Continental and not Canadian? Continental is not a reputable registry. The only reputable registry in the US is the AKC. Since you did not get the dog directly from the breeder, you don't know the exact reason or excuse most likely she didn't register with AKC. Usually the reason is it costs more, but really it doesn't. It's bc they can't. They don't have the proper paperwork to do so. Many times, the breeders don't even have the rights to breed the dogs in the first place, that's why they had to register with another registry.

And speaking of these other registries, they don't require extensive paperwork on the breeding history of the dam and sire like AKC does. They will just take your word and your check and believe you. One of our members here registered her coffee table as a purebred yorkie just to prove a point.

Also, was your dog a rehome? You say adopted, so that makes me think you got him through a rescue or shelter. Why was he not neutered? I would also agree with the poster above who said your boy will not be the same after he mates. He will mark a lot more, even in your home. He will have a much higher chance of running away since he can smell a female in heat miles away. It's just not worth it.
