Schengen ATV required for Toronto > New Delhi, via Lisbon and Vienna? [duplicate]

I have a transit visa question.

I am an Indian citizen, and I will be traveling from Toronto, to New Delhi, via Lisbon Portugal and Vienna Austria, through the TAP Airline

Similarly, I'll be coming back to Canada, with valid travel documents, via some Schengen countries, in under 10 days.

I can't find out clearly, whether I need transit visa for this itenarary.

As per Emirates transit visa tool, looks like I don't need one

But since as an Indian citizen, I need a visa for pretty much everywhere, I am confused.
I also read in other answers here that if you're just touching one Schengen area, you don't need an ATV, but I am touching two, which confuses me further.

Any help please? Sorry if this is duplicate.
