I can confirm that it is legitimate. This is an automated message from BMO Security informing you that your debit card has been compromised. If you get this call it means your debit/Interac card is now dead and you need to go to your branch immediately to replace it. It does not necessarily mean you've lost money, it means you recently used your card at a location that has had its debit machines compromised.  What is annoying is the caller ID just shows "Toll Free Service" instead of BMO so I ignored it as all other "Toll Free Service" calls I get are bogus. But if you get this call and you are a BMO customer, take it seriously and go to your branch. If you are not a BMO customer and for some reason get the call, something has gone wrong and you should contact your closest BMO branch as well. There is no "Call Type" option for "legitimate security notification" which is why I left it as unknown.

I received 2 calls from this number on 19 Aug 13. 1st call at 3PM and the 2nd at 4:30PM. No message was left on the answering machine.

Legit call! BMO automated call - included certain identifying info for our account - letting us know our non-chip debit card would cease to function in a month; need to visit a branch to have it switched out with a chip version. Non-interactive call, didn't request us to do anything during the call, simply an outbound advisory.

it can also be to follow up on a loan or mastercard application

This number is for Bank of Montreal Card Security.  They detected possible unauthorized use/skimmed card on my ATM card, and shut it down and were calling to notify me.

Bank of Montreal Security. The also detected possible fraudulent transactions on my card. Online banking and my card were both shut down. They call you to notify you and to give you steps on how to get your card working again.

Same as above

May 2010 we got the automated message as well.  I call the bank to see if it was for real and they said it was and confirmed that our acc't was fine.  Our PIN number had to be changed before the card would be useable.

BMO called me to tell me that my card was blocked due to unauthorize usage.

I keep getting a call from this number and some how i keep missing it..i dont even have an account with BMO!..urghh so annoying!..

This is a call from Bank of Montreal. Probably to tell you to activate your debit card at a BMO terminal.
