Seamless CAD/USD dual-currency account management, foreign exchange solutions, and access to BMO's US banking subsidiary for Canadian businesses with American operations, suppliers, or customers.
The Canada-US Business Relationship — Currency as Infrastructure
Canada and the United States share the world's largest bilateral trade relationship — over $1 trillion CAD in goods and services crossing the border annually under the Canada-United States-Mexico Agreement (CUSMA). For the majority of Canadian businesses engaged in this trade, the US dollar is not a foreign currency in an academic sense but rather an operational currency: they invoice American clients in USD, pay US suppliers in USD, and must manage the conversion between CAD and USD with a discipline that directly impacts profitability when the exchange rate moves.
A Canadian technology company billing a US enterprise software client at USD $500,000 annually runs its entire cost base in Canadian dollars — engineering salaries, office lease, Canadian income taxes. The CAD/USD exchange rate at the time of invoice payment determines whether that USD $500,000 converts to CAD $675,000 when CADUSD is 1.35, or CAD $710,000 when CADUSD is 1.42 — a variance of $35,000 CAD that flows directly to earnings based entirely on rate timing. Over a portfolio of US clients representing 40% of the company's revenue, this currency exposure can materially exceed the company's annual EBITDA improvement target — making FX management a first-order strategic priority, not an afterthought of the treasury function.
BMO's cross-border banking infrastructure addresses this currency management need at multiple levels: operational (USD accounts for day-to-day US dollar flows), transactional (wire transfers in USD to US beneficiaries), and strategic (forward FX contracts, options, and balance sheet hedging tools for larger exposures).
USD Operating Accounts — Holding Dollars Before Converting
The BMO US dollar business account — a foreign currency chequing account denominated in USD and held at BMO — is the foundational tool for any Canadian business with regular USD revenue or expenditure. Without a USD account, every USD receipt must be converted to CAD at the time of deposit, eliminating any opportunity to accumulate USD and use it directly for US dollar expenditures. This forced conversion means paying a conversion spread twice — once when converting USD receipts to CAD, and again when converting CAD back to USD to pay a US supplier — yielding a round-trip conversion cost of approximately 0.5% to 1.5% of the transaction amount depending on the prevailing BMO rate.
A USD operating account eliminates this double-conversion inefficiency: US customer payments deposit directly to the USD account; US supplier invoices are paid directly from the USD account; and conversion to CAD occurs only when the net surplus of USD receipts over USD expenditures needs to be repatriated to fund Canadian operations. The business converts only the net USD position, at a timing of its choosing — rather than converting every transaction individually regardless of whether a USD use is anticipated.
The USD account appears in the BMO Business Online Banking portal alongside the CAD accounts, with real-time balance visibility and full transaction history. USD payments — US dollar wire transfers to American suppliers, USD EFT payments to US payees — are initiated directly from the USD account balance rather than requiring a conversion step. The consolidated dashboard shows both the CAD equivalent of the USD account balance (at the day's spot rate) and the actual USD balance, enabling the treasurer to see the business's total liquidity position in a unified view.
Foreign Exchange Risk Management — Spot, Forward & Options
For businesses where USD exposure is material — say, USD revenue exceeding 20% of total revenue, or USD cost-of-goods exceeding 15% of total COGS — informal FX management ('convert when we need to' or 'check the rate on Google and call the branch') introduces unacceptable earnings volatility. A 5% move in the CAD/USD rate on USD $5 million of annual US revenue exposure creates a CAD $250,000 to $350,000 earnings variance — equivalent to several percentage points of EBITDA margin for a typical manufacturing business. This variance is not operational performance — it is pure currency exposure that proper hedging instruments can substantially eliminate.
BMO's FX forward contract is the most widely used hedging instrument for this exposure. A forward contract is a binding agreement to exchange a specified amount of one currency for another at a predetermined rate on a specified future date. A Canadian exporter who knows they will receive USD $500,000 from a US customer in 90 days can enter a 90-day USD/CAD forward sell contract today — locking in the conversion at today's 90-day forward rate. When the US payment arrives, the exporter delivers the USD $500,000 to BMO under the forward contract and receives CAD at the locked rate — regardless of where the spot rate has moved in the intervening 90 days. The exporter has converted currency risk into a known, certain accounting outcome.
For situations where the anticipated USD exposure is less certain — a bid-stage contract where the business may or may not win the business — a forward contract creates a liability risk: if the contract is not won and the USD revenue does not materialize, the forward contract must be settled regardless, potentially creating a speculative position. FX options resolve this problem. A USD put option gives the Canadian exporter the right — but not the obligation — to sell USD at a specified strike rate. If the USD appreciates (strong Canadian dollar, bad for the exporter), the option is exercised, protecting the budget rate. If the USD weakens (weak Canadian dollar, good for the exporter), the option expires unused and the exporter converts at the favourable spot rate. The option premium — paid upfront — is the cost of this asymmetric protection, analogous to an insurance premium.
BMO Bank N.A. — US-Domicile Banking for Canadian Businesses
BMO Bank N.A. (formerly BMO Harris Bank) is BMO's full-service US banking subsidiary, operating throughout the United States with particular strength in Illinois, Wisconsin, Indiana, Kansas, Missouri, Minnesota, Florida, Arizona, and California. For Canadian businesses that have progressed beyond simply having US customers to actually establishing US-sited operations — a warehouse, a sales office, a manufacturing facility — a USD account at the Canadian BMO parent may be insufficient. US payroll must be processed through a US bank account to access ACH; US commercial leases require a US-domicile deposit account; US corporate cards with US credit reporting require a US banking relationship.
BMO Bank N.A. provides the US domestic banking infrastructure for Canada-based companies with US subsidiaries or branches. Through a single coordinated relationship — introduced through the Canadian BMO commercial relationship manager — the US subsidiary can establish US checking accounts, US operating lines of credit, US commercial cards, and US ACH payroll capabilities, all coordinated through a unified North American banking relationship rather than requiring the Canadian parent to separately navigate the US commercial banking market.
The intercompany transfer between the Canadian operating account and the US subsidiary account — funding the US operation with capital from the Canadian parent — is managed through the BMO Business Online Banking portal as an international wire transfer (or as a same-day USD intercompany wire between BMO entities when routing through BMO Bank N.A.'s Fedwire routing number). The treasury visibility over the consolidated North American cash position — Canadian CAD operations plus US USD subsidiary — is maintained through the BMO portal's multi-currency account view, giving the Canadian CFO a consolidated liquidity dashboard spanning both operating jurisdictions.
CUSMA Compliance & US Market Entry Banking Checklist
Canadian businesses exporting goods to the United States under CUSMA (the Canada-United States-Mexico Agreement) must meet specific documentation requirements to claim preferential tariff treatment — including certificates of origin attesting to the Canadian content of the exported goods. While this is primarily a customs compliance exercise, it has banking implications: US customs brokers who clear Canadian goods at the border require the Canadian exporter to provide documentation that may include commercial invoices denominated in USD, confirming the commercial value. USD invoicing from a BMO USD operating account, with settlement to a US importer's USD account at a US bank, simplifies this documentation chain considerably compared to CAD-denominated invoices requiring real-time conversion rates applied by US customs.
For Canadian professional services firms — law firms, consulting practices, engineering companies — delivering services to US clients, the USD invoicing and collection infrastructure is similarly foundational. US corporate clients typically prefer to pay their Canadian professional service vendors in USD, through US ACH or wire — a preference that is difficult to accommodate without a USD account to receive the payment. A Canadian consulting firm without a USD account that invoices in CAD requires the US client to perform a currency conversion on their end, adding administrative burden and potentially deterring US business development.
FBAR (US Foreign Bank Account Report) reporting obligations apply to US persons (including US citizens and US corporations) who hold accounts in non-US financial institutions. Canadian businesses with US shareholders or US-citizen employees on payroll have a corporate governance responsibility to ensure their US reporting obligations are understood. BMO's cross-border team can facilitate introductions to US tax counsel with FBAR/FATCA expertise — ensuring the banking structure is implemented with full visibility into the US regulatory reporting it may trigger for US-connected parties.
