Thank you, Chair.
Thank you so much for being with us today and bringing your vast knowledge to our committee.
I want to go back to youth. Earlier, when we had CSIS and CSE here, I said that when TikTok appeared, they said the only thing they collect is an email address. They make sure that young people give them their birthdate and everything is just tickety-boo. They don't have any young people who shouldn't be on there. I challenged them at the time.
I wonder if you could just share with us a little bit. Young people sign up. They give an email address. How much more information are TikTok and Instagram, which are the two popular ones with young people, gathering and how are they gathering it? Is it of concern to you?
