Some look like cadets but some of those guys have gray hair.
The video is apparently from Remembrance Day ceremonies in 2024 held in the Edmonton Mall. (I couldn't imagine such ceremonies in mall but I guess, when you pray to the Almighty Dollar, a mall is the proper place).
Here's a link to a longer video shot from the second floor of the mall:

Chinese invaders are already here, they have a strongly fortified base at the River Rock Casino.
They are ‘commanded’ by volunteers, possibly retirees, mostly ex-RCAF, RCN, or Cdn Army.
AFA Remembrance Day ceremonies, in Calgary, there are a number of different locations where the ceremonies are held.
Of course, the National service is held at the Cenotaph in Ottawa.
I had a quick look at the vid. It looks like it was at the ‘Ice Palace’ at centre of WEM. Given that Remembrance Day is a stat holiday in Alberta, having it there, many would see it, who might never go to a Remembrance Day ceremony. There are good and bad points about having it at a mall.
