It could be but the glades around CBC are a lot tighter, this looks pretty open...and yea, the hike-to glades next to the edge are great
I'm pretty sure that is not johansen, or atleast the part that is hikeable from Tremblant. There are no Huts up there and it doesn't really look like it. My best guess is it is somewhere in the Parc Mont Tremblant.
Johansen to the southside is garbage, don't even bother with it. It's flat the entire way. Tried it once and you are pretty much stuck on the hiking trail single tracking it the entire way. If you try to break off of the hiking trail and hit any kind of powder you will just stop and have to push your way down.
Dropping in to the north side is your best bet. There is a lot of terrain out there and a lot to discover. You can pretty much drop in anywhere along a 2-3km hiking trail from the top of the edge to the top of Johansen so there are a ton of lines. There is a x-country ski trail that shoots you out when you are done. I've done a few there that were pretty good, the snow is great, barely ever do you see any other tracks and it's steep enough to get going, similar to the top of the edge.
The only problem is finding areas where the trees are not too dense... That vid the glades looked pretty open. Most of the ones I've done of Johansen are pretty thick :(
