The Ontario government released a powerful advertisement about the new "sex ed" curriculum (formally known as Human Development and Sexual Health) http://toronto.ctvnews.ca/liberals-to-release-sex-ed-ad-blitz-as-school-year-begins-1.2539952 . This new clip is by far one of the most accurate, too. I'm glad the reporter highlighted that teacher prompts and student responses are only suggestions to help navigate the curriculum - they are not mandatory, and teachers can choose to approach the specific expectations in other ways.
I could only find the full version in French - see here, https://www.youtube.com/watch?v=PYPaOTEHyJg. To translate loosely, the ad says that kids have questions and this new curriculum will help answer these questions.
