During a caisse merger, your account (folio) number changes. The caisse usually adds 100 000 to 900 000 to your former folio number. If, for example, your folio number was 12 345 before the merger, your new folio number would be
112 345 (if 100 000 was added) or 912 345 (if 900 000 was added).
If you're registered for the online statement of account, you keep your pre-merger statements. For the month of the merger, you'll have 2 statements: 1 pre-merger and 1 post-merger. If you're registered for paper statements, you'll have access only to
transactions made after the merger.
You should have received a letter from your caisse informing you of this a few weeks prior to the merger.
