Must the lessee renounce to compensation?

The Civil Code of Quebec states that there is compensation when two persons, who are debtors and creditors of each other, extinguish their debts up to the lesser of these debts. The lease usually contains a clause to the effect that the lessee renounces to any compensation and that, in order to avoid that the lessee refuses to pay sums due to the lessor by invoking that he has paid expenses for the building and that the latter were not reimbursed to him.
