Watch out for this - it is quite obvious but if you are in desperate need for cash, do not fall for it. I just received an SMS message:

First warning: Canadians do not write the $ sign after the amount. CRA will never send Interact payments to you personally - they send cheques. Then there is the URL.

A careful check reveals the perpetrators:

waldo@waldopcl ~ $ curl -I http://bit.ly/2s4N6as
HTTP/1.1 301 Moved Permanently
Server: nginx

Clearly not CRA. Be warned. Be safe.
