Hint: you want your email to be encrypted in transit. Now, lets take a look at some stats. From my earlier post about ‘Why is Canada less encrypted than the US‘?, and from Google’s Transparency Report, we dig into Sympatico. This is Bell Canada‘s brand for Internet. We see that there is no encrypted email exchanged to Bell from Google (so your friend with a Gmail account mails you on your Sympatico account).

Gobsmacked, I double checked this. First we find the mail exchanger (as below), and then we head to https://www.checktls.com/. Story checks out. Bell does not allow encryption in transit of your email, from anywhere in the world.
