Does Canada’s new sovereign wealth fund make sense given its deficit?

From BBC:

'"Norway, Singapore and Saudi Arabia run big budget surpluses which they accumulate and put into their sovereign wealth funds," Poilievre said. "Carney has no surplus, and therefore no wealth to put in such a fund."'

'But unlike Norway, Canada is in debt, meaning its sovereign wealth fund will not be paid for by revenues but rather borrowed money, says Joseph Steinberg, an economics professor at the University of Toronto.'

should the contributions to the fund be going towards the debt instead?
