Four Canadian banks run true cross-border banking between the US and Canada: TD Bank, Royal Bank of Canada (RBC), Bank of Montreal (BMO), and Canadian Imperial Bank of Commerce (CIBC). Each holds a US charter or subsidiary alongside its Canadian parent, so you can open a US dollar account and a Canadian dollar account under one institutional relationship and move money between them internally. No major US-only bank offers a comparable reciprocal program into Canada, which is why these four dominate the space.
The Four Banks That Actually Do This
TD Bank
TD runs one of the largest branch networks on the US East Coast, and its Cross-Border Banking program lets Canadian clients open US dollar accounts and vice versa.1TD Canada Trust. Cross-Border Banking The catch: the TD Complete Checking account on the US side has to be opened in a TD branch in person, so you cannot finish the whole setup remotely. TD’s density from Maine to Florida makes it a natural fit for Canadian retirees wintering along the coast.
Royal Bank of Canada (RBC)
RBC Bank describes itself as the only US-based bank specifically designed for Canadians, and it pairs US checking, savings, and credit card products in a single bundle.2RBC Bank. Cross-Border Banking for Canadians in the U.S. Its distinguishing feature is that it will pull a Canadian client’s credit file using their Social Insurance Number, so Canadians can qualify for a US credit card, mortgage, or line of credit without starting a new credit history from zero.3RBC Bank.

Bank of Montreal (BMO)
BMO has the deepest US footprint of any Canadian bank, especially in the Midwest. Its cross-border setup pairs a BMO Canada chequing account with a US dollar chequing account, and existing Everyday Bank Plan holders can add a US dollar savings account at no extra cost.4BMO.

Canadian Imperial Bank of Commerce (CIBC)
CIBC’s US subsidiary offers the CIBC Bank USA Smart Account, a US checking account aimed at Canadians who live, travel, or study in the US. It has no monthly fee, allows unlimited transactions, and supports real-time transfers between your Canadian and US CIBC accounts.6CIBC. US Cross-Border Banking It also refunds up to four non-proprietary ATM fees per statement cycle, capped at $20.7CIBC Bank USA. CIBC Bank USA Smart Account Welcome Guide
What You Actually Get in a Cross-Border Bundle
The core of every program is a dual-currency structure. You hold a US dollar account at the bank’s US subsidiary and a Canadian dollar account at the Canadian parent, so you can receive income, pay bills, and pull cash in whichever currency you need without converting each time.
Most programs also include a US dollar savings account held at the Canadian institution. This is a parking spot for US dollars you don’t immediately need, so you avoid forced conversions at bad rates. Yields on these accounts tend to be modest; the point is currency, not income.
The credit-history bridge is what makes these programs worth more than a wire transfer service. A move across the border normally means rebuilding credit from zero. RBC, for example, uses a client’s SIN to pull their Canadian credit file for US lending decisions.3RBC Bank. The Importance of Canadians Establishing U.S. Credit That can shave years off the wait for a decent credit card rate or a mortgage on either side of the border.
What Currency Conversion and Transfers Cost
Every cross-border transfer that changes currency goes through the bank’s retail exchange rate, not the mid-market rate you see on Google. Banks build in a spread. Typical markups at major banks run roughly 2% to 4% above the interbank rate, though the exact figure varies by institution, transfer size, and account tier. On a $10,000 conversion, a 2.5% markup is $250 in fees you never see itemized.
Third-party services like Wise convert at the mid-market rate and charge a transparent percentage fee starting around 0.57% for some currency pairs. For large or frequent transfers, comparing the bank’s all-in cost against a dedicated transfer service can save real money. The trade-off is speed and integration; internal transfers between your own linked bank accounts settle faster and don’t require sending money to an outside platform.
Timing matters too. Transfers submitted after the bank’s daily cutoff process on the next business day, so initiate anything time-sensitive early on a weekday morning.
How Deposit Insurance Works on Each Side
Coverage doesn’t follow your money across the border. Deposits at the US subsidiary of a Canadian-owned bank are covered by FDIC insurance the same as any other US bank. But any deposit payable solely at a branch outside the United States is not FDIC insured.8FDIC. Deposit Insurance Basics
On the Canadian side, the Canada Deposit Insurance Corporation covers eligible deposits in both Canadian and foreign currencies up to $100,000 CAD per insured category.9CDIC. Protecting Your Deposits Your US dollar savings account held at a Canadian branch is CDIC-protected, but only up to the Canadian-dollar equivalent of $100,000 CAD within that deposit category. If you’re holding large balances, split them so each side of the border stays inside its own insurance limit.
Opening the Accounts
Documentation is straightforward, but a single missing item can stall the file for weeks.
- A valid, unexpired passport is the universal starting point. Most banks also want a secondary government-issued photo ID such as a driver’s license.
- Proof of address is usually required for each country where you’re opening an account. Recent utility bills, lease agreements, or property tax statements work.
- For US accounts, banks generally require a Social Security Number or an Individual Taxpayer Identification Number. Some accept alternative ID from non-residents who have neither, but this varies by institution. For Canadian accounts, expect to provide your Social Insurance Number.
- US persons complete IRS Form W-9, which certifies your taxpayer identification number. Non-US persons complete Form W-8BEN, which certifies foreign status to the withholding agent.10Internal Revenue Service. About Form W-9, Request for Taxpayer Identification Number and Certification11Internal Revenue Service. About Form W-8 BEN, Certificate of Foreign Status of Beneficial Owner
Existing customers can often start the foreign-country application online or by phone, but some steps may still require an in-person branch visit. TD, for instance, requires the US checking account to be opened at a TD Bank branch.1TD Canada Trust. Cross-Border Banking Plan the timing if you’re setting things up before a move.
Once approved, expect several business days before the account is fully active. Debit cards ship to the address on file in the corresponding country. Credit card access may take longer. After everything is live, link the new account to your existing ones through the online portal and set up any recurring transfers or direct deposits.
The US Tax Reporting You Take On
Holding a Canadian bank account as a US person creates reporting obligations that exist whether or not you owe any tax. This is where cross-border banking clients most often get into trouble.
FBAR (FinCEN Form 114)
If you’re a US person and the combined value of your foreign financial accounts exceeds $10,000 at any point during the calendar year, you must file a Report of Foreign Bank and Financial Accounts with FinCEN.12FinCEN. Report Foreign Bank and Financial Accounts That threshold is the aggregate across all your foreign accounts, not per account. $6,000 in checking plus $5,000 in savings puts you over.
The FBAR is due April 15, with an automatic extension to October 15 that needs no paperwork. You file it electronically through FinCEN’s BSA E-Filing System, separately from your tax return.13Internal Revenue Service. Report of Foreign Bank and Financial Accounts (FBAR) The penalty for a non-willful failure to file can reach $10,000 per violation. A willful violation can cost up to 50% of the account balance or $100,000, whichever is greater, with inflation adjustments.14IRS Taxpayer Advocate Service. Modify the Definition of Willful for Purposes of Finding FBAR Violations
Form 8938 (FATCA)
Separately from the FBAR, FATCA requires certain US taxpayers to report specified foreign financial assets on IRS Form 8938, filed with the income tax return. For taxpayers living in the US:
- Single or married filing separately: total foreign assets exceed $50,000 on the last day of the tax year, or $75,000 at any point during the year.
- Married filing jointly: total foreign assets exceed $100,000 on the last day of the tax year, or $150,000 at any point during the year.15Internal Revenue Service. Do I Need To File Form 8938, Statement of Specified Foreign Financial Assets
The FBAR and Form 8938 can both apply to the same accounts in the same year. They go to different agencies, have different thresholds, and carry separate penalties. Filing one does not satisfy the other.
Where Cross-Border Banking Stops Being Simple
Everything above works cleanly for ordinary chequing and savings. Investment accounts change the picture.
The IRS classifies most Canadian mutual funds and many Canadian ETFs as Passive Foreign Investment Companies. Income and gains from a PFIC are taxed as ordinary income no matter how long you held the investment, and the “excess distribution” rules can push the effective rate above 50%. If you hold investments on both sides, keep Canadian-registered funds in Canadian accounts and US-registered funds in US accounts.
Registered Retirement Savings Plans get better treatment under the US-Canada tax treaty: US persons can defer US tax on income accruing inside an RRSP or RRIF until distributions are taken, and the old Form 8891 election is now automatic.16Internal Revenue Service. Publication 597, Information on the United States-Canada Income Tax Treaty The RRSP still has to be reported on the FBAR and potentially on Form 8938.
Tax-Free Savings Accounts are a trap for US persons. The IRS treats a TFSA as a foreign trust, so its income is taxable annually and it can trigger Form 3520 and Form 3520-A filings.17Internal Revenue Service. Instructions for Form 3520-A Most cross-border tax advisors tell US persons to avoid TFSAs entirely.
A Note for Snowbirds on Tax Residency
Spending significant time in the US can make you a US tax resident even if you’re a Canadian citizen with no intent to immigrate. The IRS applies a substantial presence test: you’re treated as a US resident for tax purposes if you were physically present at least 31 days in the current year and your weighted three-year total reaches 183 days. The formula counts all days in the current year, one-third of the prior year, and one-sixth of the year before that.18Internal Revenue Service. Substantial Presence Test
A Canadian who spends four months in Florida each winter can hit that threshold faster than they’d guess. If you meet the test but have stronger ties to Canada, the US-Canada tax treaty provides tie-breaker rules covering permanent home, centre of vital interests, habitual abode, and citizenship.19Government of Canada. Convention Between Canada and the United States of America Claiming treaty protection means filing a US non-resident return, so this needs attention before the filing deadline, not after.
Cross-border banking makes financial life between the US and Canada substantially easier, but it works best when you go in aware of the reporting obligations that come with it. Set up the accounts, and budget for a cross-border tax professional for at least the first year.
