I was able to connect with Manulife Bank account but not all the accounts show up. Only check and the Savings account show up and can be linked. The Manulife One account and other Manulife Loan accounts cannot be linked.
My colleague, LilyC already shared her answer about your concern posted on this threadhttps://quickbooks.intuit.com/community/Banking/connect-to-a-manulife-bank/m-p/341254#M384
