French canadian here. What are your privacy tools?

In the wake of the surveillance case in Québec, I just wanted to start the discussion about privacy tools. There is a lot out there and I want to gather as much different opinions as I can to get a good picture of what could work. Soon after the news got out, "La Presse" posted an article about different privacy tools that citizens could use so I guess this can be a good starting point.

Article(in french):

TLDR:
- Signal
- Facebook Secret conversations(chuckles)
- PGP
- TOR
- Tails
