I got the same message , I though some one is kidding, called back no response, CRA does not have my cell number too.

Same here.  Just got one on my work phone.

This is a scam!..the person claims to be from the CRA....the calls originate from India and use a Canadian number via VIOP. I right away realized that this wasnt the CRA and swore at the person in hindi, the individual on the other side started swearing back in Hindi!...it was quite funny!....just go along with it and have fun...in the end they will ask you to pay vis some electronic payment thing....i started laughing by that time! ...btw i told the person ill keep calling back every hour and make his life miserable....after the third time i think ive been blocked by them!

I just got a call/message from this exact number as well. Automated voice, claiming to be CRA (Canada Revenue Service), sounds legit and official, but I've called the number now several times to see what it's all about but after several rings it redirects the call and I get a busy signal, every time.

I just got the same message. My mother works for Revenue Canada and will be reporting this scam when she goes into work tomorrow.

Odd call from (613) 927-9687 - left call back number -  when calling back they identified themselves as Canada Revenue Agency.  All on a Saturday morning - quite irate that I could not tell them what my call was about when I was returning their call.
