Stack Review

What is STACK?

STACK is a fin-tech company based in Toronto and founded in 2017. The STACK Mastercard is not a credit card, rather it is a reloadable prepaid card that makes it easy for you to spend money at home and abroad without paying any fees.

The company has a partnership with People’s Trust, a financial institution with more than $6.9 billion in assets under management.

How Does The STACK Mastercard Work?

Opening a new STACK account is easy…it took me only about 3 minutes in total.

You will need your phone to download the STACK app and create an account after entering your basic personal details (No SIN is required).

After you receive your card in the mail, you can activate it and load funds using either Interac e-Transfer, Visa Debit, direct payroll deposit, or free STACK-to-STACK transfers. Additionally, you can choose to load cash up at a participating Canada Post or retailer with your STACK QR code.

Since the STACK Mastercard is not a credit card, you do not need a good credit score to sign up.


There are many reasons why Canadians choose to add the STACK Mastercard to their wallet, from zero foreign transaction fees when travelling abroad to meaningful rewards on everyday purchases.

1. Zero Monthly Fees: On this blog, I always look for an opportunity to highlight how Canadians lose money every year through exorbitant banking and investment fees. Not to worry, unlike your bank, STACK does not charge monthly maintenance fees.

2. No Foreign Exchange Fees: Banks make a lot of money from foreign currency transactions. In addition to the poor FX rate you get abroad, they also slap on a 2.5% – 3.5% foreign currency conversion fee.

While there are options to avoid FX conversion fees when you use a no foreign transaction fee credit card, there are no debit or prepaid cards in Canada that waive this fee.

Not so with STACK! When you pay with your STACK Mastercard, you pay ZERO (Nada!) foreign exchange fees. In addition to this, STACK uses the base Mastercard exchange rate which is very close to the mid-market rate and gives you the best bang for your money.

3. No ATM Withdrawal Fees: You can withdraw cash at any ATM worldwide without paying fees to STACK. Note that the ATM provider may independently charge a fee.

4. Automated Savings: The STACK app makes it easy to set a savings goal and it can automatically round up your purchases to the next $1, $2, $5, or $10 and save the difference. You can cash out your savings at any time.

5. Financial IQ: The STACK app has a financial IQ feature that analyzes your weekly and monthly spending and provides useful insight into how your money is being spent.

6. Everyday Rewards: STACK does not offer a points or cash back loyalty program. Instead, members receive offers they can easily redeem such as free membership to Amazon Prime, discounts on coffee, groceries, and gas.

7. Early Paycheque: You can get your paycheque 2 days early. To take advantage of this offer, you need to set up payroll direct load in your STACK account.

Note that the STACK Prepaid Mastercard is now available in Quebec.

Is STACK Right For You?

If you are looking at cutting your transaction fees within and outside of Canada, the STACK Prepaid Mastercard comes in very handy. When abroad, it saves you the 2.5% foreign transaction fee and ATM withdrawal fees. You also get a fair currency exchange rate.

The app makes it easy to reach your savings goals through an automatic savings plan and the ability to round up your purchases. It is also great for getting a snapshot of your spending habits.

Wondering where all your money is going? The STACK app tells you where and when.

I find their rewards to be practical. Save on your morning coffee, weekly groceries, gas, entertainment, and more. They offer great customer service and you can chat with them via the app or call them at 1-877-STACK-01.

Lastly, you get cash bonuses when friends sign up using your referral link. What’s not to like?


The only downside I see with the STACK Prepaid Mastercard is that:

  • It is not a credit card, so if you were hoping to use the card to build a credit rating, that is not possible.

Overall, I like the STACK Mastercard, find it practical, and an excellent addition to my suite of money-saving cards, which includes the KOHO Prepaid Visa Card ($20 welcome bonus).

  1. Hi, I just got this card by using your link (yes mobile) but I don’t see $25 credit yet. Do you know how long it will take to get a credit or should I already see it?

  2. Hi,
    I’m traveling to Vancouver end of September for 6 months. Since I am Swiss, am I eligible to a Stack card? and where can I get a physical card in Vancouver. In other words can I just simply convert cash into a Stack prepaid?
    Thanks a lot (interesting reading you by the way).

    • Hi Nathan,

      I believe you need to be considered a Canadian ‘resident’ to be able to apply for STACK.

      As per their website:

      “Who can apply for STACK?
      Any Canadian resident outside of Quebec who is the age of majority or older in their province can apply for a STACK Prepaid Mastercard and STACK account.”

      Safe travels!

  3. Hi,
    Do you know if Stack checks with the CRA for Canadian tax residency status? I’m Canadian citizen with Canadian address Ontario driver license Canadian banks account (both credit bureau states my address is in Ontario) but I’m not a Canadian tax resident since I only spent 2-3 months per year in Canada.

  4. Hi,
    Does stack card charge any other kind of fee? I know they don’t charge for exchange rate. suppose I load 500 dollars on my card and want to use 500 dollars at different times. that money still be there or do need to load some extra money for their fees?

    • I want to use their card for a long trip in New Zealand. Is it a good idea or i will risk to have a lot of decline with local store and groceries ?
      Someone has a feed back of their card use in foreign country ?

  5. Stack is crap. They don’t honour what they promise. Card was declined multiple times, even though enough funds were in the account. Customer service very rude. Highly do not recommend.

    • I have had issues with authourizations as well. It is usually an address issue – but when i speak to the merchant, or Stack, there are no solutions. Biggest problem is then money is held for 5 business days – which sucks. So i’m always nervous to use it because I’m never 100% confident it will work.

  6. They change conditions on promotions without informing you. They update their terms and conditions and you are suppose to read it every month. When you talk to customer service they are rude and refuse to help you and if you cancel card they will hold your money for 45 days any balance that you have since its prepaid card.

  7. I just received my Stack card and noticed that despite this article pointing out that “the company has a partnership with People’s Trust which is a CDIC-insured financial institution with more than $6.9 billion in assets under management”, the Stack cardholder agreement specifically states “Funds loaded onto the Card are not insured by the Canada Deposit Insurance Corporation.” I suggest the article be updated to know longer imply that Stack is CDIC insured.

  8. We have had Stack in Europe for around 6 months.

    A lot of machines in airports set the exchange rate and you have choice, ie, you pay full bank fees.

    You are limited to 2000 CAD a month, so if you load 5000 CAD on it will take 3 months to withdraw. Kind of like a ponzie scheme, Stack has your money, you can not use it. Yes some is for money laundering but 2k a month.

  9. Signed up through your referral link but didn’t notice anywhere where I had to enter anything about a specific referral. Is the referral $5 promo still on?

    • @CJ: Thanks for reading!

      Just a quick note to mention that people may have different experiences with the STACK Mastercard depending on their peculiar needs and expectations. I have personally used the card several times abroad, including in Africa and Europe and have always been able to access my cash.

      • Same here. Got it because I was tired of getting ripped off on foreign currency exchange. Great rates. Haven’t had a problem yet, but so far use it mostly (though not exclusively) for on-line purchases. People that don’t have problems don’t tend to seek out & post on blogs like this. I think that’s why the comments are skewed a tad.

  10. This card is great in an ideal sense however I have just had the pleasure of dealing with them twice in less than 3 days about cancelled or declined transactions with merchants and the card still processing the charge and showing up as ‘pending’ on their end but still taking the money regardless. Their customer service solution is to just ‘wait’ for the money to be returned onto the card as the ‘pending’ will drop and the money will show up again…… So while that’s all great in theory, if the cancelled transaction was a $1000 hotel room and STACK still takes the charge and money anyways…. You’re stuck waiting over 10 days for them to ‘return’ it to you….. Because we are all money trees?? With tons of money to just be held hostage because they can’t come up with a better system on their backend to not process declined or cancelled transactions by the merchant?? How does that make any logical sense. Absolutely ridiculous and makes the card look pointless if you’re stuck with tons of ‘pending’ declined transactions with money held up because the card will sometimes work or not work at foreign merchants… Which is the whole point of the card????? FOREIGN TRANSACTIONS??

    • SarahH, yes, it sucks. But this isn’t specific to Stack. It’s the nature of regular credit cards and pre-paid cards too.

  11. Absolutely horrible and canceling. It’s never available. You add funds and automatically get a ‘sorry, etransfer isn’t working’. Always- this last time no notice, nothing – simply not loading. I’m lucky I have other options but I would NEVER recommend this to someone that will depend on it for traveling or actually having to use it as their only source. It simply is aweful. They do not allow reviews on their only social channel (Facebook), not surprising but truly hope people research before wasting their time. Revolt was way better and sadly is gone from Canada.

  12. So I signed up last week to use this card. I tried to access my account I used the ID and Password (it is 100% correct. I wrote it down and have been using it) it says invalid credentials.

    Like… Is this thing even possible? They just blocked me randomly. I have money loaded in the card too..
