You should read the survey you quoted. You'll find it overlaps when the regulations started - May 2014. It took over six month for Health Units to inspect salons and make sure they were following the regulations. I can see why the researcher didn't wait until 2016 to do the follow up survey. It wouldn't have given them the results they wanted. 
Fake beliefs, check the research and you'll see a tan create protection, some research says up to a protection equal to a SPF of 11. I would say that was protection. If you want to talk about using chemical sunscreens, make sure you apply it correctly, most don't. Most apply 1/3 to 1/2 the amount, if you used an SPF 30, that changes the SPF rating to approximately 2 to 4.
