Hi Roland - I found that with QB too.  They couldn't help me.  I called CRA and she helped me get the T4's filed.  I sign into the CRA web site with the "Represent a Client" because I don't own the company and if you have an access code, you can file them that way.  When you E-File through QB, it creates an xlm? file and that's what you upload on the CRA web site.  Call around 8:00 so you're not on hold for hours.  I hope this helps.  Good luck!
