“Pursuant to s. 130 of the CJA, the court has the discretion to make an order for interest at a rate other than as prescribed by s. 128 (pre-judgment) or s. 129 (post-judgment). However, the manner in which that discretion is exercised is mandated by s. 130(2) of the CJA. That subsection provides that “the court shall take into account” six specific factors (ss.130(2)(a)-(f)). Those factors include:
a) Changes in market interest rates;
b) The circumstances of the case;
…
e) The amount claimed and the amount recovered in the proceeding; [and]
f) The conduct of any party that tended to shorten or lengthen unnecessarily the duration of the proceeding.”
