Is it the same as for CA's? What validation letter is used with OC's and where can I get a copy? Also, using the Validate, Estoppel and ITS sequence does anyone have a good ITS letter? I have a couple of CA's that have not validated or refuse to accept a validation letter. For the one that refuses to accept the validation letter, how soon should they get the estoppel letter which I'm sure they will refuse to accept also. Another one has gotten the estoppel letter and has not responded and the information on the CRA has not changed which means they have not updated so how soon should they get the ITS? This whole system is GREAT and I've sure learned a lot. I appreciate all the help I've received here especially the stuff by psychdoc.
