Question about Canadian military uniform

[KeyboardPatriot]

Here is a picture that I found online that depicts a column of Canadians wearing camo in the center, and on the left and right, columns of Canadians wearing more official uniform. The question is this: on the left and right, are they wearing No 1, No 2 or No 3? And could someone post what No 1, No 2 and No 3 look like for enlisted men? Apparently, it can vary by regiment, so please post the most common ones for all three.

FYI, the Canadian Army will begin to transition to a more traditional Commonwealth-style uniform later this year. The uniform is more or less in line with the pre-unification uniform.
