Yes, I assumed that was generally known.
My point was that "Champagne Service" was a brand/product name - like advertising "The World’s Most Effective" or "Less is More” or "“Better Ingredients. Better Pizza”" - which have never been held to factual standards, per US law. I'd say "Champagne Service" falls into that realm, especially when qualified with actual services. (iirc - "Puffery is not illegal and is a common method used in advertising.").
The actual description of the service being offered specifically calls for "sparkling wine".
I don't know if product marketing tag lines are legally binding in Canadia, but in the US there's no case here.
