How long should I wait for the tax refund . It's been nearly 30days.

Please ensure you have received your 6 digit confirmation number (if you used NETFILE). If you have received a confirmation number, then you must wait for the CRA to process your return:

I filed in March and it is now mid-May.  Am I too patient?

As per the citation from the CRA`s website above, "If you filed your return on or before April 15, wait four weeks before you call." I'd say you've been more than patient enough, and it's time to call.
