When a pensioner requests a reassessment because a pensionable condition has deteriorated, is it properly said to be making an application for a new pension?

In contrast, when a pensioner requests a reassessment because a pensionable condition has deteriorated, the pensioner may then properly be said to be making an application for a new pension. There would be no reason to backdate an increased pension, awarded on the basis of a deterioration, to the time of the original pension application, because the deterioration had, by definition, not then occurred. Further, since the decision in Leclerc v. Canada (Procureur général) (1998), 1998 CanLII 7445 (FC), 150 F.T.R. 1, involved a pension entitlement, it is not necessarily dispositive of the issue in the present case.
