scam.

Okay I just did some further research on this number/caller, and it is indeed a scam. For example, check here... http://800notes.com/Phone.aspx/1-(613) 927-9687 , dozens of people have identified this and reported it as a nuisance call.

I got that earlier today (Saturday).  Just a robocall saying that they, CRA, had been trying to get me and will file a law suit.  That, of course, is not CRA methodology.  I'd know more if I called back, but I won't.

Same here.  Just got one on my work phone.

Exactly...same message

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.
