Most Ys in Canada still have them. Mine does, and from what I've seen online, other Ys do as well.
Universities are hit and miss now My old university got rid of them years after I graduated, and it has totally destroyed the locker room dynamics. It's now cold, impersonal, and eerily silent. Some universities like the U of T still have them from what I've been told.
I went to a really upscale gym in downtown Toronto a year ago that has stalls and a large communal shower. I used the communal shower as did some other young guys and older guys, but there were also older and younger guys using the stalls. I guess the older guys using the stalls were the guys that couldn't get over themselves when they were younger and complained about having to use communal showers when they were the norm. I would think being older now that they would be happy that anyone wanted to see them naked. Believe me, I wasn't bothered in the slightest by not seeing those older guys naked. Same at my current Y. For every one hot guy I see naked there are at least a hundred I could have gone a lifetime without seeing naked. All kidding aside, I think it's sad when a guy is past 20 and still can't get naked around other guys. I look for gyms that still have them because I find there is a friendlier atmosphere in those locker rooms. In my experience, gyms that offer ultra privacy also attract an ultra unfriendly and uptight crowd. Gyms that have communal showers attract a friendlier easier going crowd.
