Joyeuses Fêtes à tous à toutes - Is this accurate french?

Question

I was just given this line from a Canadian government French translation department, but I don't think that it makes sense, does it? > Joyeuses Fêtes à tous à toutesTranslates to “Happy Holidays to all to all”, doesn't it?----------J'ai reçu cette phrase du département de traduction du gouvernement Canadien, mais je ne suis pas certain qu'elle soit correcte, l'est-elle?> Joyeuses Fêtes à tous à toutesLa traduction serait «*Happy Holidays to all to all*», n'est-ce pas?

Answer 1

The word "et" is missing.

Moreover, we usually start in French with the feminine form (like "Mesdames et Messieurs"), so I would say "Joyeuses fêtes à toutes et à tous" but "Joyeuses fêtes à tous et à toutes" is also correct.

Answer 2

I would say Joyeuses fêtes à tous et à toutes. It's OK to just say Joyeuses fêtes à tous, meaning to all, male and females, but the second part à toutes, emphasizes that it goes to all, including and specifically to the females.
