Senate legislation states that "Normally requests for deferred standing must be communicated within one week following a missed examination of the last day to submit course work. The period during which the University is officially closed for December holidays is not counted in the determination of deadline days."
For circumstances arising after the withdrawal deadline, you would normally be expected to arrange deferred standing (more time to complete the outstanding final assignment or final exam). Even if you petition for late withdrawal, the committee may decide that your circumstances warrant deferred standing. Since you would then be subject to the deferred standing application deadline, it is important that you always petition immediately following the development of your circumstances.
Faculty of Liberal Arts & Professional Studies legislation states "that petitions for an extension of deferred standing will not be accepted more than 1 week (7 calendar days) after the date of the missed deferred exam, or the deadline for completion of the deferred term work without evidence of circumstances which account for the delay."
