Businesses need cash for two main purposes: covering day-to-day expenses and maintaining reserves for unexpected costs or future plans. But traditional banking products often force a trade-off between keeping cash accessible and earning interest on it. Money in a chequing account is ready for bills, while funds in a savings account may need to be transferred before they can be used.
The right business account can help you make more of your operating cash without sacrificing liquidity. Whether you need a traditional savings account or a more flexible option for working capital, the key is finding a competitive rate that lets your money earn interest while remaining available for the payments you need to make. Understanding your working capital needs can help you decide which account makes the most sense.
A traditional savings account works well for reserve cash, meaning money set aside and not expected to move, like an emergency fund or tax set-aside. It doesn't work as well for operating cash, the money that funds near-term payments: payroll, vendor bills, card purchases, tax remittances. If a savings account can't make a required payment, you have to transfer the money to an operating account first, and it may stop earning while it waits in chequing.
That's the gap that usable cash fills: the share of operating cash that can stay in an interest-bearing account without blocking a required payment. Float, Venn and Wealthsimple are built around this. They let some operating cash earn interest while it also funds business transactions, instead of forcing a choice between earning and spending.
The value of usable cash can’t be overstated, and it becomes even clearer when you can put a dollar amount to it.
Let’s say a business keeps $500,000 in cash and needs $150,000 available for monthly operations. A 2% savings account on the remaining $350,000 earns about $7,000 per year. An operating account paying 1.75% on the full $500,000, which covers all required payments, earns $8,750. The lower rate yields $1,750 more because an additional $150,000 stays interest-bearing.
Subtract monthly and transaction fees before comparing the result. A high marginal rate on a small top tier, or a bonus on only net-new funds, should never be applied to the entire balance unless the terms allow it.
Once you know how much of your balance is usable, the next step is matching to the right account. Here’s what to look for with providers to get the most from each of these areas.
A good fit here lets CAD and USD balances keep earning while they're actively funding cards, bill payments and reimbursements, instead of forcing you to choose between interest and liquidity. Look for no minimum balance, a rate that applies to the full amount (not just a top tier), and support for the payment types your business actually runs, like PADs if payroll depends on them.
Float and Venn both build around this model, with Venn adding a broader payment set including PADs, though it isn't available in Quebec. Wealthsimple can also work well for eligible incorporated businesses running CAD-based operations, provided their combined assets qualify them for a useful rate.
For money that isn't expected to move, the priority shifts to a strong whole-balance rate, low-friction transfers, and clear CDIC protection. A whole-balance CAD rate with free bank-to-bank transfers avoids the trap of a high top-tier rate that only applies to part of your balance. Keeping CAD and USD reserves at the same traditional bank (as BMO allows) can simplify tracking. If a reserve can move through free internal transfers rather than a per-debit fee, that's worth more than the headline rate alone.
The right account keeps USD balances doing something productive rather than parked, whether that means funding operating workflows directly or earning a straightforward rate while it sits. Look for whether USD gets its own rate and rules instead of riding along with a CAD product, and whether the account matches how your business actually uses USD: spending it, holding it, or just moving it.
Float and Venn are two options that tie USD directly to operating tools like cards and bill pay. BMO offers direct-bank USD savings with progressive rates. Manulife favours easy transfer access over yield.
At scale, the right fit depends on whether the balance needs to stay usable for near-term payments or can sit as pure surplus for 30 days or more. Look for a rate that keeps improving as the balance grows, solid support for both CAD and USD if the reserve spans both, and a clear sense of how much will actually fund operations versus sit untouched.
Decide how much cash can remain usable and how much exceeds the applicable protection limit.
The annual interest estimates assume a constant Canadian-dollar balance for one year, simple interest before tax, and no transaction fees unless marked in USD. Progressive accounts apply each rate only to the corresponding portion, while whole-balance accounts apply one rate to every eligible dollar.
Below is an example of the interest you could earn on CAD and USD cash held across providers.
The other options currently support CAD only, so aren’t featured on the USD rates table.
Canada Deposit Insurance Corporation (CDIC) covers eligible deposits up to $100,000, including principal and interest, per insured category at each member institution. The legal holder, account category and underlying member determine how that limit applies.
A trust account or partner bank doesn't automatically insure every dollar above the applicable limit. If your business holds more than $100,000, map each balance to the underlying member, insured category and aggregation rule before allocating the cash.
With those comparisons complete, let’s take a closer look at each highlighted option.
Float is one option for businesses looking beyond a traditional bank. Its Business Account pays a variable 2.5% base rate on CAD and USD Cash balances, calculated daily and paid monthly. There is no minimum and no base-rate cap.
The real advantages are that your cash doesn’t have to sit still to earn it, and that the product offerings become part of using Float. Pre-funded Float Cards, Bill Pay and Reimbursements draw from Float balances, so cash assigned to those workflows keeps earning until it is spent. There is no monthly account fee, no fee to send or receive ACH/EFT and no fee from Float for a connected-account withdrawal. Intermediary banks can still deduct SWIFT fees.
Float fits Canadian businesses that hold operating cash in CAD and USD and need cards, vendor payments or reimbursement payouts. At a constant $500,000 CAD balance, the 2.5% base produces about $12,500 over one year.
The benefits of using Float pay. Toonie Tours, a Canadian tour operator who receives payments in both USD and CAD, earned more than $6,000 through Float's interest-bearing accounts while that money stayed available for corporate cards, vendor payments and guide reimbursements. Nothing had to be locked into a savings account. Instead, their operating cash earned a return in the gap between when revenue landed and when it went out the door.
Like any financial platform, Float suits businesses whose needs align with its products and workflows. Before getting started, see how Float fits alongside your existing banking setup and how your business manages spending, payments, and expenses.

Venn is a technology company, not a bank. Eligible CAD and USD balances earn a standard 2% annualized rate while supporting cards, reimbursements, Interac transfers, EFT/ACH, PADs, accounts payable, invoicing and payment approvals.
Essentials costs $0 monthly and charges $2 for EFT, ACH or Single Euro Payments Area (SEPA) transfers and $10 for international wires. Plus costs $40 monthly with free local transfers and $8 international wires. Pro costs $100 monthly and lowers international wires to $6. Receiving local payments and international wires is free.
Venn fits a Canadian business outside Quebec that wants CAD and USD balances connected to payment and expense workflows.
Venn isn't a CDIC member itself. Client funds are pooled in trust with Bank of Montreal and kept separate from corporate funds, so coverage depends on BMO's CDIC status rather than Venn's, and it's worth confirming whether that $100,000 limit aggregates CAD and USD before parking a protection-sensitive balance there.
Venn is also unavailable to Quebec businesses. Opening online requires identity, business, beneficial-ownership and compliance verification.
With Wealthsimple, you can draw from the same CAD balance for linked prepaid business Visa, bill payments, corporate income tax, GST/HST, and payroll remittances. Wealthsimple Business Chequing pays interest on that balance, with no monthly fee or account minimum.
The whole balance earns one ongoing rate, set by combined personal and business assets, client status and, for some tiers, an eligible direct-deposit boost:
This account fits eligible incorporated businesses that run in CAD and the interest rates are beneficial for businesses already qualifying for a competitive Wealthsimple tier. A company at 2.25% would earn about $11,250 on a constant $500,000 balance while keeping supported chequing functions in the same account. A company at the default 1.25% would earn $6,250, so checking the combined-asset tier is part of the decision.
Businesses that do best with Wealthsimple are generally Canadian-controlled private corporations registered in Canada, or charities or associations registered with the Canada Revenue Agency. The application criteria limit ownership to a single layer and require a nine-digit federal business number. Sole proprietorships, partnerships, financial entities and strata or condominium corporations are not supported.
The account supports CAD only. Incoming USD wires are converted to CAD for a fee, and outgoing USD wires are not supported. Incoming e-Transfers, direct deposits and wires are free.
With this account, progressive CAD and USD rates give surplus cash a separate home without a monthly fee, minimum balance or lockup, and can be paired with BMO business chequing for daily operations. Both currencies use progressive tiers, so at $1 million CAD only the portion from $500,000 upward receives 2%, producing about $18,940 (the USD schedule produces about $18,740 at $1 million USD), and amounts above $50 million in either currency fall into a 0% excess tier.
The CAD tiers are:
The USD tiers are:
BMO fits a business that wants CAD and USD savings at the same bank as its operating account. Internal BMO transfers are free. What should you know before choosing BMO?
Branch withdrawals and bill payments cost $5 each, so frequent operating use can quickly eat into the interest earned. Deposits are cheaper but not free. Branch or ATM deposits cost $1.25, deposited cheques cost $0.20 and direct deposits cost $1.25. Cash deposits cost $2.25 per $1,000 of notes or $100 of coin. Electronic statements are free; paper statements cost $4.
BMO offers online or branch opening for sole proprietorships, corporations, partnerships and unincorporated associations.
For a reserve account alongside a primary operating account, the CAD Business Advantage Account at Manulife pays 1.45% on the full balance, calculated daily and paid monthly. There is no monthly fee, minimum deposit or lockup. Posted rates apply to aggregate deposits up to $5 million (or its USD equivalent) in each account type. Manulife may adjust the rate above that amount.
Manulife's separate USD account pays 0.20%. It also has no monthly fee or minimum and supports transfers to another USD account at a Canadian bank.
The CAD account suits a smaller business that wants a simple reserve account alongside its primary operating account. Bank-to-bank transfers and deposits are free. Bill payments and outgoing Interac e-Transfers cost $1, while cheques cost $1.50. Canadian business tax payments cost $2 after a one-time $25 enrollment fee.
CAD balances can fund PADs, bills, cheques, transfers and enrolled tax payments. However, Manulife does not support business debit/credit cards or employee reimbursements, so those workflows should stay elsewhere. USD access is limited to transfers to another USD account at a Canadian bank, so keep USD bill and PAD needs in another account.
Eligible organizations include corporations, partnerships, trusts, estates, associations, condominium corporations, unions, charities and not-for-profits. Applications can be completed through an advisor or by phone, not online.
This is an account built for small-to-medium sized businesses looking to grow their surplus cash balances. To earn interest, a business must maintain a daily balance of at least $10,000 daily. The CAD-only account has no monthly fee and a maximum balance of $2 million. The excess tier earns 0%. Interest is progressive:
This account fits an existing Scotiabank business that can keep at least $10,000 in reserve and move funds to another Scotia account. Self-service internal transfers are free. A $500,000 constant balance earns about $8,850 at ongoing rates.
Automated banking machine (ABM) withdrawals, cheques, direct payments, bill payments and other debits cost $5.50 each. Frequent operating transactions reduce the interest retained after fees.
Applications can begin online or through a branch appointment.
The businesses getting the most out of their cash aren't choosing between earning interest and staying liquid, they're matching each dollar to the account built for its job. That's what separates the best business savings accounts from a default chequing setup: long-term reserves go where the rate and CDIC protection fit best, payroll and routine bill pulls stay in a primary chequing account built to handle them, and the operating cash in between no longer has to sit idle just because it needs to stay accessible.
That last piece is where most businesses leave money on the table. Float's Business Account closes that gap, paying interest on CAD and USD balances while they still fund day-to-day spending. If usable cash makes up a meaningful share of your working capital, it's worth exploring Float to see how much of your cash could be earning.
Yes, interest earned on a business savings or operating account is considered business income and must be reported to the CRA, regardless of which institution holds the account or whether it's a traditional bank or a fintech like Float or Venn.
Since Float and Venn aren't CDIC members themselves, they hold client funds in trust accounts with a partner bank (Float uses Scotiabank; Venn holds funds with BMO). Coverage depends on the terms of that trust arrangement and the partner institution's CDIC status, so it's worth confirming the current coverage limit and structure directly with the provider before parking a large balance there.
Yes, and most businesses do. The article's core argument is that this traditional split, interest-earning savings paired with a zero-interest chequing account, often leaves usable cash earning nothing while it waits to cover payments, which is why some businesses are shifting operating cash into interest-bearing operating accounts instead.
There's no single rule, but common guidance is 3 to 6 months of operating expenses. The right amount also depends on how predictable your revenue is and how much of your operating cash could instead be classified as "usable cash" and kept earning interest rather than sitting idle.
It varies by provider rather than following a universal rule. Some accounts in this comparison charge a per-transaction fee instead of a hard limit (e.g., BMO and Scotiabank charge $5 to $5.50 per debit), while others like Float and Venn are built to support frequent transactions without per-transaction penalties.
