My worry

Since my ex-company was restructuring last year, I am not manage to prepare the company's staff EA form on time. Actually I still don't know what the status of the company tax file application handing by the company tax agent. I am wondering shall I prepare all the forms first. After we get the employer file number then I just plug in the number. I think I better contact the tax agent soonest as possible to prevent any delay of the company Form E submission.
