You are right bro....its not mentioned in the AOR ...but yes its mentioned in the PER mail.... I have just now gone through it once again...
Please inform the visa office of any changes in your application (e.g. birth or adoption of a child, marriage or common-law relationship, new occupation or employer, submission of an Arranged Employment Opinion approved by Human Resources and Skills Development Canada, change of address, change of e-mail address, change of immigration representative, etc). Please include a letter identifying what the changes are and any relevant supporting documents.
Thanks once again...
