Suppose you're relocating from Toronto to Vancouver next month and planning to return in six weeks' time. Where would you prefer your mail to be directed? Perhaps you're operating a small business from your home and would rather not have clients appearing at your residence.
This is precisely where P.O. Boxes prove invaluable. They've been Canada's reliable answer to postal challenges since Confederation in 1867.
What exactly is a P.O. Box? In simple terms, it's your private, secure mailbox located at a Canada Post facility. It’s like a temporary mailing address, where you can safely pick up your mail when you’re away.
Countless Canadians depend on P.O. Boxes for various purposes – from business correspondence to deliveries from online retailers like The Bay or Canadian Tire.
Canada Post offers a wide range of services, and learning how to navigate them is key to maximizing their value.
This guide will cover everything you need to understand about P.O. Box services across Canada, from initial setup to what items are actually delivered to your postal box.
A P.O. Box, also known as "post office box" or "postal box," is a locked space inside a Canada Post branch where you can get mail and small packages. Canada Post gives you a unique box number and keys or a combination to use the box. Your P.O. box is now your official mailing address, which is different from your home address.
Unlike community mailboxes, P.O. Boxes remain open 24/7 in major cities. Pick up your mail when it’s convenient for you, rather than depending on carrier delivery times. Canada Post manages more than 6,200 post offices across the country, with P.O. Box services available in most locations.
Deliveries to your P.O. Boxes are fairly simple across Canada. Canada Post handles your mail sorting and places items directly into your assigned box. Smaller parcels fit inside, while larger deliveries are set aside with a pickup notice at the counter. You control who uses your P.O. Box address and can collect your mail whenever it’s convenient for you.
Canada Post offers a comprehensive range of P.O. Box services to meet the diverse postal needs of Canadians.
Standard P.O. Boxes: If you are a small business handling routine mail, this is ideal for you. Standard P.O. Boxes easily accommodate letters, publications, and smaller parcels.
Large P.O. Boxes: If you are a business with higher mail volumes, this type of mailbox will serve your needs better. Large P.O. Boxes efficiently store legal documents, commercial catalogues, and medium-sized packages.
Personal P.O. Boxes: Such P.O. Boxes prioritize privacy while providing convenient, flexible access.
Business P.O. Boxes: These often include corporate identification options, serving as professional mailing addresses. Many locations feature clusters of boxes in different sizes, allowing businesses to scale their service as their needs grow.
Specialty P.O. Boxes: These cover short-term rentals for seasonal residents and mail redirection services for travellers. Canada Post tailors availability and features based on local demand and facility capabilities.
Remote workers and freelancers benefit greatly from Canada’s P.O. Box services to create professional mailing addresses. Instead of sharing your home address for work correspondence, a P.O. Box helps you distinctly differentiate personal addresses from business addresses. Your clients see an official address, which is far more professional than a home-based setup.
For small business owners, a P.O. Box is more than just a mailing address. It helps your business look professional and established. Displaying a P.O. Box on your website, invoices, or business cards shows clients you run a credible operation. At the same time, it keeps your personal address private, which is especially useful for government paperwork, registrations, and other official correspondence.
People who move frequently, including students or professionals relocating for work, benefit from P.O. Boxes because they provide a stable mailing address. The P.O. Box securely holds mail, ensuring uninterrupted receipt of important correspondence, regardless of residence changes.
Canadians who value their privacy often turn to P.O. Boxes to keep their home addresses more secure. All your online shopping, contest entries, and magazine subscriptions can go straight to your P.O. Box instead of your front door. This helps reduce unwanted visitors and gives you better control over your family's privacy.
If you are a seasonal resident, whether you’re heading north for the summer or south for the winter, P.O. Boxes are essential. Your mailbox stays safe and organized while you're away, so you don't have to worry about bothering the neighbours or missing anything important during your time away.
Canada Post has five different box sizes to fit various sizes of mail. Here's a complete breakdown of P.O. Box dimensions and recommended uses:
| P.O. Box Size | Dimensions (H x W x D) | Best For |
| Small | 5 cm x 12 cm x 23 cm | Individual users, minimal mail |
| Medium | 12 cm x 12 cm x 23 cm | Regular mail and small packages |
| Large | 23 cm x 12 cm x 23 cm | Small businesses, magazines |
| Extra-Large | 23cm x 23cm x 23cm | High-volume business mail |
| Jumbo | 30cm x 23cm x 23cm | Large businesses, bulk mail |
Modern P.O. Boxes across Canada are built with strong metal construction and reliable locking systems. Each key is unique and difficult to duplicate, giving you peace of mind that your mail is secure.
Many larger Canada Post locations offer round-the-clock access to P.O. Boxes. Whether you stop by before work, after hours, or on weekends, you can collect your mail on your schedule.
When a package is too large for your box, Canada Post places a pickup slip inside. Simply bring the slip and your ID to the counter, and you can collect your parcel quickly and easily.
For frequent travellers and seasonal residents, Canada Post offers mail forwarding and vacation hold services. These features make it easy to manage your mail while you’re away or changing addresses.
All individuals 18 years and older may apply for P.O. Box rental services in Canada. Canadian citizenship is not mandatory, though proper identification must be supplied. Minors are welcome to apply with parental permission and adult co-signatory support.
The application process requires current, government-issued photo identification, including driver's licenses, passports, or provincial identification cards. Please ensure your identification remains valid and displays your complete name and photograph clearly.
You'll also need to provide recent proof of residence—utility statements, banking documents, or rental agreements dated within the last 90 days are acceptable. This verification assists Canada Post in maintaining accurate customer information and service standards.
Business P.O. Box applications involve additional documentation requirements, such as business registration papers, incorporation records, or partnership agreements. Sole proprietors may present personal identification combined with business name registration documentation.
Step 1: Check availability
Some locations do not provide P.O. Boxes, and there may be waitlists for popular sizes. Call ahead or check online to make sure that service and size are available.
Step 2: Choose your P.O. Box size
Choose a size based on how much mail you expect to get and receive it. Upgrading later may require waiting for a larger compartment to open up.
Step 3: Fill out the application for the P.O. Box
Make sure to fill out the application correctly. Check your contact information carefully because Canada Post uses it to send bills and other notifications. Mistakes can slow down activation.
Step 4: Show the required ID and documents
Bring the right forms and ID with you. If everything is right, staff will check your documents and process your application in about 10 to 15 minutes.
Step 5: Pay for Your P.O. Box
Settle your P.O. Box rent at the counter with cash, debit, credit, or a certified cheque. Some locations can even set up automatic payments so you don’t have to think about renewals.
Step 6: Pick Up Your Keys and Box Number
You will get your keys and your new box number after you make your payment. They will guide you to where your box is and tell you how to get to it. Check the keys to make sure they work before you leave.
Government-issued photo identification is non-negotiable for all the applications. Your ID must be original, current, and clearly legible. Photocopies or expired documents won't satisfy P.O. box requirements.
Proof of address establishes your connection to the service area. Recent utility bills, mortgage statements, or lease agreements work well. The document must show your name and current address within the past 90 days.
Business applicants need valid business registration documentation. Provincial incorporation certificates, federal business numbers, or partnership agreements establish legitimate business operations. Solo proprietors combine personal ID with business name registration.
Additional identification might be required in certain circumstances. If your primary ID lacks current address information, bring supplementary documents. Bank statements, insurance documents, or official government mail can be used to verify your address.
You have to go to a Canada Post branch in person to fill out a P.O. Box application. Some places have online pre-application forms, but you have to go in person to finish the setup and collect your keys.
You can look up box prices and availability online before you go. Canada Post's website has information about P.O. box services and current fees that are specific to each location. This preparation makes your in-person visit easy.
You can make a phone call to find out if boxes are available and what paperwork is needed. Staff can also put you on waitlists for the box sizes you want if they are not available.

| Cash on Delivery (COD) | COD purchases cannot be delivered to P.O. Boxes because payment must be collected in person. Use alternate payment methods instead. |
| Oversized Packages | Items that exceed your box’s dimensions (e.g., large appliances, furniture) are redirected to the counter for pickup. Canada Post determines limits based on your box size. |
| Prohibited Items | Hazardous materials, perishables, and illegal goods cannot be sent to P.O. Boxes, in line with Canada Post’s standard mailing restrictions. |
Delivery Notice Cards appear in your P.O. Box when items exceed compartment size. These slips contain tracking information and pickup instructions. To collect the package, you present the card along with valid government-issued identification at the designated counter.
Most locations offer package pickup during regular business hours, Monday through Friday. Some larger centres provide extended pickup hours.
You need a government-issued photo ID matching your P.O. Box registration for package pickup. A Canada Post employee will verify your identity before giving you the package. This security measure protects P.O. Box holders from unauthorized pickup.
The amount of time packages remain at locations depends on the type and local rules. Regular packages usually stay for two weeks before they get processed for return. Express Post and registered items may have different holding times depending on service level.
P.O. Box access hours depend on your local Canada Post branch configuration. Many locations provide 24/7 lobby access for P.O. Box holders, even when retail counters close. Larger centres often maintain extended P.O. Box access schedules.
Holiday schedules affect box access in some locations. Statutory holidays might limit lobby hours or building access. Check with your local postal facility for holiday P.O. Box access arrangements during Christmas, New Year's, and other closures.
After-hours P.O. Box access policies vary by location and building security. Some facilities provide key card systems or extended lobby hours. Rural locations might have more restrictive P.O. Box access due to security concerns.
Proper addressing format ensures smooth mail delivery. Use the "P.O. Box [number], [City], [Province] [Postal Code]" format for domestic mail. International mail should include "Canada" as the final line.
P.O. Box addresses work perfectly for online shopping with most retailers. Enter your P.O. Box information as your shipping address during checkout. Some services might require phone number verification for P.O. Box deliveries.
Business correspondence using P.O. Box addresses maintain professional appearance. Include your business name above the P.O. Box line for clear identification. This format works for invoices, contracts, and customer communications.
P.O. Box address sharing requires careful consideration of privacy needs. Provide your P.O. Box address instead of your home address for subscriptions, contests, and online accounts. This practice protects your residential privacy effectively.
Canada Post offers flexible mail management options to ensure you stay connected, no matter which place you go.
Temporary mail forwarding allows you to receive your P.O. Box deliveries while travelling within the province, across Canada, or abroad. For a set fee based on destination and duration, Canada Post redirects your P.O. Box mail to a specified address.
Permanent moves, such as relocating from Alberta to Ontario, require cancellation of your existing P.O. Box. At the same time, you can request mail forwarding to your new address. This ensures uninterrupted delivery while you update your contacts with your new details.
Vacation holds provide another layer of convenience. During extended absences, Canada Post securely stores your P.O. Box mail until your return. This prevents overflow and ensures your correspondence is protected while you are away.
