Do you have to wait 30 days after disputing with the CRA and get their response before sending a DV to the CA. And also please correct me if I am wrong..... you should send a DV before you PFD even if you know you owe it, and you should send them (DV,PFD, and GW) CMRRR. Thanks for any comments I am completely green at this repair business and just soaking up all the info I can find
