Yes, and its available to J, Aeroplan elites and *G in any class. It's all over CDG with the signs pictured in the previous post.
you will arrive in terminal 2A which is very small so if your connecting flight is from there you will have a lot of time to kill. Otherwise there is a bus between terminals in a interval of 5-8 min.
You will have to go through baggage check/security at 2A which will on a bad day take 10min with Accès no. 1.
So plenty of time.
Edit: was there on Monday arriving from Canada so can confirm Accès no. 1 is up and running.
