While changing planes at YYZ T1 next week (SYR-YYZ-DUB) I'd like to mail some letters to people in Toronto. I have NEXUS so going through Canadian immigration into the landside terminal shouldn't be a problem.

There's reputedly a mailbox near aisle H and the newsstands sell stamps. Can anyone say whether the mailbox actually exists, and the landside newsstands really have stamps? Tnx.
