What do you mean by that? Did they tell everybody to do the oath in both languages?
I did the oath in Montreal a couple of months ago and we were specifically told that we could choose a language or do it in both languages.
I did the oath in both languages, but not because I had to do it. I chose to do that because 1) I speak both languages and I'm proud of this since I had to learn both of them, and 2) they check if you're doing the oath and I wanted to avoid any misunderstanding (what if they look at your lips during the oath in the other language?)
In any case, I wouldn't say that I was asked to do the oath in both languages.
