I will be the first person to admit that I send a lot of mail. Thank you cards, forms, cheques to pay bills for things we're closing up in Quebec (we don't use any of their "Quebec-approved" banks so we have no choice but to pay by cheque. I KNOW.) , and more. It's not often that I'm keen to head over to the post office in our neighbourhood just to mail a letter, but there's just nothing at all on the Canada Post website that helps you to find a mailbox near you. Since I'm new to the neighbourhood, these things are just not well-ingrained yet.
I had seen a few people in our neighbourhood asking this very same question (twitter's #hintonburg feed is so great), so after a couple of aimless trips around the nearby streets on my bike, searching for a mailbox, I decided to take matters into my own hands. As a result, the Hintonburg Mailbox Map was born. It lists the mailboxes I've found to-date, and I'll be keeping it up to date as much as I can.
Missing a mailbox? Let me know!
