In 2007 during discovery (at Ontario Superior Court of Justice) I undertook to provide income information for 2000-2006, that is "details of income and Income Tax statements". Now, referring to the undertaking, the adverse party demand me to provide the same information (calling it "sources of income") up to 2009. Am I under obligation to provide income information generated long after discovery took place? Also do they have the right to ask for sources of income where only the size of income would be necessary to define incurred losses?
