I live in Canada and you're right I haven't heard of them.
And no I don't live in Nova Scotia.
But I am fairly involved in the dog show world, and they are not an accepted breed with the CKC (Canadian Kennel Club) so therefore they cannot be shown.
I would be interested in knowing the name of the show that the dogs are shown in as well as the "organization" that recognizes them.

One other thing is that dogbreedinfo is not the greatest site when dealing with dog breeds as they list many mixed breeds as "purebreds" some examples being the toy munchkin, schnoodles, cock-a-poos, etc.
