Is the petitioner required to contribute to the costs and expenses for both children?

In addressing the respondent’s submission that the petitioner ought to be required to contribute to these costs and expenses for both children, I am specifically mindful of the decision of Carr, J. in Chambers v. Chambers, 2004 MBQB 239 and the necessity to first consider s. 7(1.1) of the Guidelines to decide whether the expenses claimed are indeed “extraordinary expenses” and, thereafter, to advert to the criteria set out in s. 7(1) to make a final determination.
