In Ontario the Ontario Provincial Conference governs agreements for BACU Locals and IUBAC Locals. IUBAC Local 2 BC has arranged reciprocal arrangements with the health and welfare and pension plans for all locals in Ontario. Attached here (click) is the BACU Agreement and here (click) is the IUBAC Agreement. The terms are the same essentially. For reciprocity you will have to sign reciprocity papers to bring your money home for the benefit plans.
Safe travels if you are heading that way. If you have any questions call the union hall or the president.
