Your CWB Optimum Mortgage migration hub
Find the most up-to-date information about the migration of your CWB products and services
Your lending products will migrate in early 2026
At least one month before your scheduled migration, you’ll receive important information about your migration date, your products and services, and any actions required on your part.
We’re committed to making this process as smooth as possible. Most of your migration will take place automatically, but you can always refer to your Migration Letter for detailed information about activities you may need to complete for a successful migration.
