Thank you very much for your answers. It will be really helpful! 
I will meet someone at the Canadian Wildlife Minister so I will be able to show him some huge dogs in our breed and I will help him to saw the difference between our breed and the two ”dogs” involved in this case.
I send you an old link to a French forum, when you will be able to see the two “dogs”. Ha ha the owner say that they are Czechoslovakian Wolfdogs…

Apparently they are from Romania with micro chip... But I don't have the kennel name yet... If there is one...
Thanks again for your help, it’s really important for our breed in Canada!
Take care,
Stéphanie
