Canada Post Community Mailboxes
Notice: Blue Boxes removed from Canada Post Mailboxes
Canada Post has recommended the removal of blue boxes from all their mailbox sites in the City of Markham. This will allow them to resume full responsibility for site maintenance, including the clean-up of mail-related litter and waste.
In November 2025, those blue boxes were collected by Miller Waste, sorted and then recycled into new plastic products.
We apologize for any inconvenience. However, Markham has experienced ongoing issues with these blue boxes, including contamination from pet waste and illegal dumping, which makes it difficult to properly recycle collected materials. Additionally, unwanted flyers are often left behind, resulting in wind-blown litter throughout our parks and streets.
For more information including how to report an issue at a mailbox, or how to stop receiving unwanted flyers, see below.
- Canada Post Maintenance
Canada Post is also responsible for clearing the snow around the mailboxes and making them accessible.
How to report an issue at a mailbox location:
- To report mail-related litter, contact Canada Post at 1-866-607-6301 or canadapost.ca/support
- To report illegal dumping of household, contact Markham at 905-477-5530 or customerservice@markham.ca
- Bring It Home
Be a good neighbour and bring home all your mail including those unwanted advertising flyers. They simply go in your blue box at home.
Flyers left behind, stuffed in between mailboxes or on the ground creates litter that makes its way onto your streets and into your parks. Although, community mailboxes are owned and managed by Canada Post, picking up street and park litter is done by City staff and dedicated residents. Reducing litter reduces waste going to the landfill.
- How to Stop Receiving Unwanted Flyers
If you were using the blue boxes located at mailbox sites, that indicates you do not wish to bring home some of your mail. If so, Canada Post can help with the Consumers' Choice program. It’s easy and it’s your choice!
To stop receiving unaddressed advertising mail:
- Simply place a small note in your mailbox “No Flyers Please”
- Still getting flyers? Submit a request to Canada Post.
Even if you choose to be part of the Consumers’ Choice program, you will still receive:
- Government mailings – public interest newsletters, service alerts
- Materials from Elections Canada, provincial/territorial chief electoral officers and municipal election officials (or the deputy returning officer), including material from political parties and electoral candidates during an election
- Any addressed mail, including addressed advertising materials – such as Costco membership flyers
- Community newspapers (without commercial inserts/enclosures) – only inserts in the public interest are acceptable
