Frequently asked questions

Here are some frequently asked questions about the Chrono mobile app

How do I know if I'm using the most recent version of the application?

Search for 'Chrono' in the AppStore or Google Play (depending on your device). If a more recent version is available you'll be prompted to update the application.

What happens if I’m on the bus and the 120-minute validity period of my “YUL Aéroport Mtl-Trudeau” digital fare has expired?

When you board the bus, your fare must be activated. Once on board the 747 bus, the driver will give you a transfer that will allow you to travel in zone A (agglomeration of Montréal) by bus, metro, train or REM for the next 24 hours. This transfer also acts as proof of payment for your trip on the bus.

However, we recommend that you activate your fare only a few minutes before departure.

I activated my “YUL Aéroport Mtl-Trudeau” digital fare by mistake, even though I didn’t take the 747 bus. Can I recover it?

No. Fare activation is irreversible. Activating the fare requires dual validation by the user to avoid this handling error. In accordance with the policy on transit fare exchanges and refunds, a “YUL Aéroport Mtl-Trudeau” digital transport fare purchased or activated by mistake will not be eligible for a refund.

What are the exchange and refund conditions for the “YUL Aéroport Mtl-Trudeau” digital fare?

The “YUL Aéroport Mtl-Trudeau” fare is neither exchangeable nor refundable.

Is it possible to activate several fares for family or group travel?

Yes. You can activate several fares if you are more than one passenger. A fare must be activated for each passenger. All passengers must remain together during the trip.

  • However, you can only activate one fare at a time:
    • Access your fare wallet (by clicking the ticketing icon or via the main menu in the top left-hand corner), select a fare, activate it and repeat the operation.
    • To view activated and valid fares individually, return to your fare wallet and select “Activated.”

If a fare is activated by mistake, it cannot be cancelled or refunded.

How long is the “YUL Aéroport Mtl-Trudeau” digital fare valid once activated?

Once activated, the fare is valid for 120 minutes. You can check the activation and expiry times at any time via the app. When the validity period has expired, the fare will display “expired.”

Once on board the 747 bus, however, the driver will give you a transfer that will allow you to travel by bus, metro, train and/or REM throughout the agglomeration of Montréal (zone A) for the next 24 hours.

Do I need an Internet connection to activate the “YUL Aéroport Mtl-Trudeau” digital fare?

Unfortunately, the “YUL Aéroport Mtl-Trudeau” digital fare purchased on the Chrono app cannot be used without an Internet connection. An Internet connection (WiFi or cellular data service) is required to complete the purchase, as well as to activate the fare and ensure its validity during use.

From that point on, your fare will be valid for 120 minutes.

Can I activate my “YUL Aéroport Mtl-Trudeau” digital fare before boarding the bus? 

Yes. Please note, however, that the 120-minute validity period will begin upon activation.

When should I activate my “YUL Aéroport Mtl-Trudeau” digital fare?

Your fare must be activated no later than when you board the Société de transport de Montréal (STM) 747 bus. From the moment the fare is activated, it is valid for 120 minutes.

Do I need to create an account to purchase the “YUL Aéroport Mtl-Trudeau” digital fare?

Yes, an account is required. To create an account, you must provide a valid email address and your credit card information. Your transaction receipts will be sent to this email address.

What languages is the app available in?

The Chrono app is available in French and English. The app language is based on the language set on your phone. If your phone is configured in English, then the app will be in English. If your phone’s language is not English or French, the default language of the Chrono app will be French.

Do I also need to purchase a “YUL Aéroport Mtl-Trudeau” fare for a child travelling with me?

In accordance with current regulations, children aged 11 and under travel free of charge on public transit services at all times when accompanied by a person aged 14 and over who is responsible for their supervision and has a valid, validated fare.

In this case, a person aged 14 and over can purchase their “YUL Aéroport Mtl-Trudeau” digital fare, activate it and show it to the 747 bus driver within two hours. At that time, if accompanied by a child or children aged 11 and under, the children will be admitted on board without a fare.

A person aged 14 and over may not accompany more than five children aged 6 to 11. At all times during the trip, children must remain in the presence of the person accompanying them.

Children aged 12 and over, or any children in addition to the above-mentioned ratio, must pay their fare.

Is the “YUL Aéroport Mtl-Trudeau” digital fare accepted on all public transit services?

No. The fare is only valid on STM bus line 747. It cannot be used on any other bus or other modes of public transit (metro, train, REM, paratransit).

Once aboard the 747 bus, upon presentation of an activated “YUL Aéroport Mtl-Trudeau” digital fare, the driver will visually validate the fare and give you a transfer that will allow you to travel by bus, metro, train and/or REM throughout the Montréal agglomeration (zone A) for the next 24 hours.

Can any other public transit fares be purchased in the Chrono app?

No. Only the “YUL Aéroport Mtl-Trudeau” digital fare is currently available in the app.

For which mode(s) of transportation is data available on bicycles being allowed on board?

Currently, commuter trains provide data on whether or not bicycles are allowed on board. For other modes of transportation, we encourage you to check with your transit operator.

Why is there no real-time indicator for all arrival times?

For various reasons, real-time data may not be available for certain arrival times on the same line. Check back later, the data may be updated.

What do the blue waves next to the arrival time mean?

They mean the arrival time displayed is an estimate in real time.

What does a crossed-out arrival time mean?

A crossed-out arrival time indicates a modified schedule. This means that the mode of transportation is behind or ahead of schedule, and that a new estimated arrival time is available. It can also mean a cancelled arrival time.

I see two arrival time indicators: minutes remaining and an actual time in brackets. Which one should I trust?

Both indicators are accurate. The first shows the number of minutes remaining before the stop or station is reached. The second gives you the actual time of the arrival (hh:mm). You can use both indicators for greater accuracy.

If the bus or train is late or early, you will see a third indicator. The scheduled arrival time will be crossed out, and you will see the new estimated arrival time in real time (in minutes remaining and with the actual time).

What is the FLEX service?

FLEX is one of Communauto’s two distinct car sharing services. It does not require a reservation and offers more flexibility. You can block a FLEX vehicle up to 30 minutes in advance.

This service is only available in certain areas of the Island of Montréal. See the FLEX zone.

Cars are available throughout the FLEX zone and can be left anywhere within the zone or at a FLEX drop-off point at the end of your trip.

While using a FLEX vehicle does offer you certain parking privileges, it also has restrictions. Please consult the FLEX parking guide to learn more.

What does “blocking a vehicle” mean?

Once you’ve located a nearby FLEX vehicle on the Chrono app, press “Block”. The car will be reserved for you for up to 30 minutes. This will give you time to reach the car and unlock it.

What do I do if I need more time to reach the FLEX vehicle I have reserved?

You cannot extend the allocated blocking period.

You can, however, cancel the vehicle block and block it again immediately afterwards. This will give you an additional 30 minutes.

If your 30 minutes have passed and you haven’t picked up the car yet, check the Chrono app to see if it’s still available and block it again.

You can also block another FLEX vehicle once the previous blocking period has expired.

I located the FLEX car that I blocked. What is the next step ?

You have to unlock the car to take possession of it. There are two ways to unlocking the car:

  1. From your FLEX blocking page in Chrono: you'll find details of the car (location, time remaining in blocking period, type of vehicle, etc.) and, at the very bottom, the 'Unlock' button that you can click on.
  2. Using your OPUS card or RFID key: to unlock the car manually.
Can I block more than one FLEX vehicle at a time?

No, you can block only one FLEX vehicle at a time. If you wish to block a new car, please note that your current block will be automatically cancelled.

How do I cancel a vehicle block?

On the home screen, you will see an orange rectangle indicating your current vehicle block. Click on it to see all the details about the blocked car. At the bottom of the screen, you’ll see the “Cancel this block” button.

What should I do if I cannot unlock my FLEX car ?

If you are more than 25 metres away from the car or have not shared your position in the application, you will receive a message in the application asking you to indicate the last three characters of its plate number.

If this does not resolve the situation, contact the Communauto support service.

I have finished my FLEX trip, how do I end it?

After putting the car key back in its place and locking the doors, select your FLEX trip in the Chrono application and click on 'End the trip'.

How and why should I register my OPUS card?

By registering your OPUS card, your card and fares will automatically be covered by the replacement guarantee if lost, broken or stolen. In other words, you can replace your card and recover your valid fares when you report it to your transit agency’s customer service department as lost, broken or stolen.
Registration is free. Visit your public transit agency’s website to register your OPUS card. If you already have a reduced fare photo OPUS card (for schoolchildren, students or seniors), your card is automatically registered and your card’s content is covered by the replacement guarantee.

What is Communauto?

It is a car sharing service where members can reserve a vehicle up to 30 days in advance, for a maximum of 30 days. This service is very similar to renting a vehicle from a car rental agency, except that the vehicles are self-service (24/7). Cars can be accessed at various Communauto stations throughout the metropolitan area. The vehicle you reserve with this service must be brought back to the same station where you originally picked it up.
In Chrono, you will find Communauto in the “Mobility” tab under the map. This service is also available from the app’s menu.

What does “booking a vehicle” mean?

This is a period when you plan to have the exclusive use of a Communauto vehicle. Since you are reserving a specific vehicle, it is almost guaranteed to be available unless the previous user is delayed in returning the vehicle (if there’s a problem, please contact Communauto).

How do I cancel my reservation?

To cancel a Communauto reservation in Chrono :

1- Go to the Communauto page via the app’s menu or under the “Mobility” tab on the home page;

What are the rates and how will I be billed for my booking ?

Communauto offers different packages to suit your needs. For questions about rates and the payment terms of their service, consult the Rates section of the Communauto website or contact the company directly.

Can I reserve a car without a Communauto membership number?

A Communauto subscription is required to make a reservation on the Chrono app. Visit the Communauto website to join now.

Why isn’t there a station-based vehicle available at the time I want?

Station-based Communauto vehicles can be reserved up to a month in advance for a maximum of 30 days. It’s possible that all the cars that meet your criteria have already been reserved for the time you requested. Here are a few tips to find a car:

1- Change the search period. Cars may be available at a slightly different time (different pick-up or drop-off time);

2- You can also reserve a car at a different station that you can still access;

3-Try to block a car with the service Flex.

Can I change my car’s pick-up time?

3- Click on the reservation you wish to see and consult the details (address, vehicle type, etc.).

Can I have more than one active reservation at a time?

There is no limit to the number of bookings you can have in your account as long as they are for different periods. In other words, you can have only one reservation for a specific period.You can book future trips up to a month in advance.

Don’t forget to cancel your reservations to avoid being billed if you decide to withdraw. Doing so will allow other members to reserve the newly released vehicle.

What do I do if I’ve finished using my car before the reservation return time?

If you return your car to the station earlier than expected, you will be able to end the reservation. By opening the current reservation in the Chrono app and pressing “Terminate Booking”, you make the vehicle available for someone else to reserve. Learn more

Can I return my car to a different station from the one where I picked it up?

No, station-based vehicles must be returned to the same station.

How can I bookmark my favourite addresses?

When you search for an address, a bookmark icon will appear on the right. Tapping this icon will open a window where you can select a name and an icon for your new bookmark.

Why does a point of sale appear in chrono when it’s no longer open?

Although this is a rare occurrence, there is sometimes a delay between the closing of a point of sale and the updating of our data source. Please feel free to contact us if you notice any inaccurate information on the results page.

Why are opening hours unavailable or inaccurate?

The opening hours of participating retailers originate from a web service external to Chrono. Retailers are under no obligation to provide their opening hours.

Do I need an internet connection to use this feature?

Yes, you must have access to the Internet and be connected in order to use this feature.

Do I have to enable geolocation in order to use this feature?

No, unless you want to view points of sale near your current location. You can activate and deactivate the GPS in the application settings via the main menu of the Chrono application.

Can I add a point of sale as a favourite?

Yes, you can set a point of sale as a favourite address and choose an icon for it.

Can I view the fares or services offered at a point of sale?

No, this information is not available at this time. The metropolitan ticket offices offer most of the transit fares available in the territory.

Do I need an Internet connection to use this feature?

Yes. You need a network connection to read your card’s content.

Is this feature available on tablets with NFC technology?

No, this feature was designed specifically for smartphones and cannot be downloaded on tablets.

On my Android phone, I was able to read my card’s contents at first, but it does not work when I try to read it again.

For the OPUS card reader to work properly, you need to move your card away from your phone, then move it back into place for the second reading.

It takes me several tries to read my OPUS card.

Your phone’s protective case, shell or NFC location might be causing the problem.

  1. Please take your phone out of its case or shell and try again.
  2. While maintaining contact between your phone and OPUS card, slide it down your phone. It will vibrate once you hit the detection area.

Depending on the phone model, you might need to place your OPUS card on the front or back of the phone to read it. Try positioning the card against the phone’s surface in different spots to check all possible locations. If you are still having difficulties reading your card’s contents, please let us know by using “Contact us” in the app or by sending us an email indicating the issue at support_chrono@artm.quebec.

Are there any security issues or risk of my personal information being stolen when we use NFC technology?

No. This technology is widely used in the banking sector and has a proven track record for security and reliability. It also has scalable security components and always offers the best possible protection.  Rest assured that the Chrono application transmits no personal information via NFC.

Will all smartphones and operating systems support this feature?

No, not every phone will support this feature since some older models lack the necessary software for the reader to function properly.

Can I buy transit fares on the app after the card has been read?

No, the Chrono app does not support transit fare purchases at this time. The application will undergo public testing to identify key parameters for further development and possibly support in-app purchases in the future. We are unable to provide a timeline for this project’s completion at the present time.

Does the Chrono app save my OPUS card’s contents after reading it?

No, the application does not store any information.

How and why should I register my OPUS card?

By registering your OPUS card, your card and fares will automatically be covered by the replacement guarantee if lost, broken or stolen. In other words, you can replace your card and recover your valid fares when you report it to your transit agency’s customer service department as lost, broken or stolen.

Registration is free. Visit your public transit agency’s website to register your OPUS card. If you already have a reduced fare photo OPUS card (for schoolchildren, students or seniors), your card is automatically registered and your card’s content is covered by the replacement guarantee.

Why is my OPUS card being detected as invalid?

The OPUS card may have been invalidated after being reported as lost or replaced. You can learn the exact reason by contacting customer service at your public transit agency. You can also get a new OPUS card at a public transit point of sale.

What does the message “Your phone is not compatible with the OPUS card reader” mean?

Your phone model does not support the NFC feature needed to read OPUS cards.

Why isn’t my phone detecting my OPUS card, even after several tries?

There are several reasons why your card might not be detectable:

  1. Not positioning the card against your phone correctly: Phones will usually, but not always, have the detection area located in the upper part of the phone. While maintaining contact between your phone and OPUS card, slide it down your phone. It will vibrate once you hit the detection area.
  2. Not holding your OPUS card against your phone for long enough: The OPUS card must be kept flat against the phone for a few seconds for the reader to work properly.
  3. Not being able to read the OPUS card chip: Some cards use older chips that cannot be read or recognized by the NFC feature.
  4. Protective case or shell interfering with the NFC signal: Please remove your phone from its case or shell and try again.

If you are still having difficulties reading your card’s contents, please let us know by using “Contact us” in the app or by sending us an email indicating the issue at support_chrono@artm.quebec.

Does it also read “Solo” and “Occasional” cards?

Yes, you can also read “Solo” and “Occasional” card content.

How do I read my OPUS card’s contents?

If you have an Android phone, ensure the NFC feature is activated. For iPhones, NFC is activated by default.

Press your OPUS card against the upper part of your mobile phone. (The detection area’s location depends on the phone model and might be located on the front or back). It will vibrate once it connects. Now, hold your OPUS card still for a few seconds so the app can recognize it.  You can click on the following link for a visual, step-by-step guide: https://www.artm.quebec/en/chrono-blog/

What does “Reading an OPUS card” mean?

This is the action of viewing an OPUS card’s contents. This process lets you see if your card contains transit fares and their status (type, number, expiry dates, etc.).

How can I find out how crowded my bus is?
To find out the level of crowding for a specific bus, select a stop. The schedule for this stop will open and an icon will appear next to the schedule when available.
