I can’t accurately recall whether it was validated or not ... but my education and employment were overlapping and it didn’t caused anything bad so far . Validation occurs when u have filled all columns but cic requires your original signature that means your form will show NO validate. But still if you want to add LOE go for it . Better to explain and feel light . Have your criminality passed ???thanks a lot for the help...so it means that your document was not validated..i mean there was "no" written under the validate button..am i correct..also my job and studies are overlapped due to which my form does not validate..i was thinking to write a one page LOE and add it to the pdf file..whats ur suggestions
