How does MACPASS work?

The MACPASS transponder is a small electronic device that attaches to the windshield of your vehicle and contains information that identifies your account. As you approach a toll lane on either the MacKay or Macdonald Bridges, an overhead antenna identifies your MACPASS transponder and deducts the toll.

You can use MACPASS in ALL lanes on the Macdonald and MacKay Bridges. For added convenience, there are “MACPASS Only” lanes on both bridges.

Watch our MACPASS installation video here.

The transponder works in most vehicles with standard windshields. Vehicles with heated windshields, windshields with chromium oxide for UV protection, or windshields with a built-in antenna can interfere with the MACPASS transponder working propery. In this case, please contact or visit the our MACPASS Customer Service Centre for advice on installation.


If you have a sticker transponder, you must remove the old sticker from the vehicle and deactivate it. Contact MACPASS to receive a new sticker.

Please de-activate any stickers you no longer have online or by calling the Customer Service Centre.

Can I use my MACPASS transponder at other toll facilities?

You can use MACPASS at the Cobequid Pass and Confederation Bridge tolls by creating an account with them.

If you are applying for a MACPASS account and you already have an E-Pass or a STRAIT Pass, indicate your transponder serial number (located on the lower left hand corner of your transponder (i.e. CAHD ########) on your MACPASS application. If you have a commercial account with several transponders, you should attach a list of the transponder serial numbers to your MACPASS application.

To set up an account, call:
Cobequid Pass: 1-877-727-7104
Confederation Bridge: (902) 437-7300

Please note: You should not have more than one transponder in your vehicle.

Sometimes the toll gate does not lift. Why?

Most commonly, the toll gate does not lift when:

  • Users let their account balance reach zero
  • Users do not use the transponder correctly

If you allow your account balance to reach zero, you will get a stop signal in the lane when you attempt to use your MACPASS. If this happens you will need to make arrangements to make a payment or your account may be suspended and a $10.00 reactivation fee will be applied.

Please note: As your account balance nears zero, a low balance message will appear under the “GO” sign as you travel through the toll lane.

Other reasons why the toll gate may not lift are:

Speeding through the tolls: Motorcycle, moped and scooter drivers are encouraged to come to a complete stop and swipe their MACPASS in front of the MACPASS reader located above the coin basket in all cash lanes. All other vehicles must reduce speed to 25 km/h to ensure that the MACPASS transponder will work correctly. All vehicles should be prepared to stop at any time while going through the tolls.

Defective transponder: Unfortunately, it is possible that your transponder may be defective. To get a new transponder just log onto your account at www.myMACPASS.com or visit the MACPASS customer service centre between 8:30am – 5:30pm, Monday to Friday. Report and return your defective transponder in person or by mail at PO Box 39, 471 Princess Margaret Blvd, Dartmouth, NS, B2Y 3Y2.

How do I pay for my MACPASS?

You can choose from the following payment options:

Automatic credit-card replenishment :
The convenient credit-card replenishment option is the easiest way to make MACPASS payments. When you use a valid VISA, MasterCard or American Express card, your MACPASS account will be replenished automatically. For automatic replenishment the amount we request varies depending on how much you use the MACPASS. The usage is based on a three-month average. When your account reaches 1/3 of your average monthly amount (low balance threshold) your credit card will be charged that amount.

Pre-authorized debit (PAD):
To make payments using pre-authorized debit you must provide your banking information, as well as the preferred date during the month you would like your account debited for MACPASS usage. Debit replenishment occurs monthly on the PAD charge date that you selected. This is a once per month payment type.

Please contact customer service at (902) 463-3100 to confirm the day of the month and adjust the payment amount if needed.

Please note: If the account balance on the payment date is above your monthly payment amount, no debit payment will be processed for that month.

Are there any fees associated with MACPASS beyond my monthly usage charges?

Most people will not have to pay additional charges for using their MACPASS. However, fees will apply for the following reasons:

  • If your account is suspended for any reason there is a reactivation fee of $10
  • The minimum payment on an account is $20
  • If, during an electronic funds transfer on your account, you have non-sufficient funds, there will be a fee of $10. After two non-sufficient funds transfers, we will deny electronic funds transfer as a payment option.

Motorcycles and Mopeds

I drive a motorcycle/moped/scooter. What is the best way to use my MACPASS?

For safety reasons, motorcycle, moped and scooter drivers are encouraged to avoid the MACPASS only lanes.

If you have a hard shell transponder, swipe the MACPASS in front of the MACPASS reader to lift the toll gate. MACPASS readers are located above the coin basket in all cash lanes.

If you have a sticker transponder, you must ensure it is installed properly. Since all bikes are different, please consult the MACPASS Customer Service Centre to ensure the right location for your bike.
