I wouldn’t use the word “assured” to describe separation in your first scenario, KR. The aircraft taking off might have to abort the take-off for some reason, the landing aircraft might have to do a go around for some reason …
CASR 91.370 is about when the aircraft taking-off commences the take-off run. It’s about the circumstances at that point in time, and I would hope that at that point in time we’re thinking about, or have already thought about, all of the things that could go wrong.
