Ontario Holdback Release – Contractor Paperwork

Ontario holdback release planning should be tied to the project record, the invoice trail, substantial performance or completion status, published notices where applicable, and unresolved deficiencies or claims. Contractors should avoid treating holdback as an afterthought at final payment.
