01 · The connection
Scotia OnLine, via Plaid's OAuth integration
Scotiabank is one of the major Canadian banks with full Plaid OAuth support. When you pick Scotiabank inside Mozaic, a Plaid-managed popup loads scotiabank.com and you sign in with your sign-in card (your access card or username) and password the same way you would on Scotia OnLine. If you have the Scotiabank Mobile Approval push enabled on the Scotiabank app, the popup waits for the tap on your phone. If you use SMS or email verification instead, the code prompt appears inside Scotia's popup.
After you authorise the connection, Scotia issues a read-only OAuth token to Plaid. Plaid forwards it to Mozaic, your accounts appear in the app within a minute, and a rolling sync schedule keeps them current. The token is good for roughly ninety days before Scotia requires you to reauthenticate — Mozaic surfaces an in-app reauth nudge ahead of the expiry so the connection doesn't quietly fail.
02 · Every Scotia account, one roof
Chequing, savings, Visa, Amex, mortgages — all of it
Mozaic reads every product Scotia exposes through Plaid. Deposit side: Preferred Package, Basic Bank, Ultimate Package, Student Banking Advantage, the MomentumPLUS Savings tiered-rate buckets, Money Master, and the TFSA and RRSP cash savings accounts. Credit side: Scotia Momentum Visa Infinite, Passport Visa Infinite, Scene+ Amex, Scotiabank Gold American Express, Platinum Amex, Value Visa. Liabilities: Scotia Line of Credit, ScotiaLine Home Equity, Scotia Total Equity Plan, and Scotiabank mortgages — with current rate and principal-paid trend.
The Amex cards are one of the things Scotia does differently from the other Canadian banks — they issue American Express on the same Scotia OnLine profile as their Visa cards. The Plaid integration covers both networks under one connection, so you don't have to maintain two separate links for one institution.

03 · Scotia quirks worth knowing
Mobile Approval, the sign-in card, and Scotia iTRADE
The Mobile Approval push is the smoothest way to clear Scotia's out-of-band check during the connection. If you have the Scotiabank app installed and have enrolled Mobile Approval, the OAuth popup tells you to approve on your phone, you tap once, and the sign-in completes. If you don't use Mobile Approval, the same popup falls back to SMS or email verification — pick the channel that matches your Scotia OnLine profile, enter the code, done.
Scotia iTRADE accounts are not part of this connection — and not part of any automated connection today. iTRADE lives on a separate system from Scotia OnLine, and neither Plaid nor SnapTrade currently exposes it for read-only data sync. If you hold positions at iTRADE you can still track them in Mozaic as manual assets — balances, holdings, and notes you update on your own cadence — so they sit beside the rest of your accounts in net worth and goals. The day brokerage coverage opens up we'll surface a one-click upgrade from the manual entry to the API-driven sync.
The sign-in card is Scotia's name for the access card number used to sign in to Scotia OnLine — typically a 16-digit number from a Scotia debit card, or a username you set yourself. Either works in the OAuth popup; pick whichever you actually use on scotiabank.com. If you've forgotten it, the popup has a reset link that takes you to Scotia's own recovery flow.
04 · Beyond the chequing line
Scotia sits in a bigger picture once it's connected
The point of connecting Scotiabank isn't to see your Scotia balance — Scotia OnLine does that already. The point is to see Scotia alongside everything else: your Wealthsimple TFSA, your Questrade margin, a TD mortgage from a previous home, the US 401(k) you still hold. Mozaic composes them into one net-worth line in your reporting currency, narrates cash flow across the whole picture, and tracks the goals you actually care about against the accounts that fund them. The Scene+ Amex rewards balance even surfaces as a counter alongside the credit-card spend pattern, so the points you're earning aren't mentally siloed.
The institution is just the start of the story — the rest is what your money is doing across institutions, and Scotia is a sturdy anchor account for a lot of Canadian households.
