I haven't seen child-targets marketing from them in decades here in Canada. Where do you live and what do you see?

Example of prohibited advertising: The Rappido Company is advertising a remote-controlled toy car like one seen in an animated film. The advertisement is broadcast on Saturday morning on a TV channel for children during a cartoon program. The ad is in animated film format and shows a young boy who is thrilled to be operating his high-speed car. This ad would be prohibited.
But there's no mention of product placement. I imagine that would be hard to account for.
Can't really confirm that assumption, even outside of Canada where there's no regulation in place. Last time I remember McDonald's specifically marketing to children was in the 80's, since then they've changed their marketing approach several times focusing more on how "healthy" the food supposedly is or how it's locally sourced.
