I believe that once something is “officially” announced at the Federal level (it’s currently burried within a budget), it should just be a case of advising HR that it’s a Federal requirement now (providing with the announcement or link to this). That department will need to provide the data required–having the directive from CRA should (in theory at least) be all that’s needed to get the ball rolling.
I’m watching for that official CRA notification myself. 😉
