After an objection is filed, the CRA is required to reassess a tax return "with all due dispatch" according to subsection 165(3) of the "Income Tax Act". This may have different meanings depending on how busy the CRA is, the time of year, and other factors. Subsection 165(3) says:"On receipt of a notice of objection under this section, the Minister shall, with all due dispatch, reconsider the assessment and vacate, confirm or vary the assessment or reassess, and shall thereupon notify the taxpayer in writing of the Minister's action."
