Choosing the right business bank account is one of the most important early decisions for any Canadian small business owner. The right account saves you money on fees, simplifies your bookkeeping, and gives you access to credit and services as your business grows. This guide compares the top business banking options available in Canada in 2025.
Many new entrepreneurs start by running business transactions through their personal chequing account. This works in the short term but creates serious problems:
For incorporated companies, mixing personal and corporate funds can actually pierce the corporate veil, exposing shareholders to personal liability. The CRA also expects corporations to file separate corporate tax returns (T2), and having commingled funds makes this far harder.
Not all business accounts are created equal. Here are the most important factors to evaluate:
Business account fees at major Canadian banks range from $0 (for basic online accounts) to $150+ per month for premium packages. Most fall in the $15–$65/month range for small businesses. Some banks waive fees if you maintain a minimum balance.
Big banks typically charge per transaction beyond a monthly allowance. A "transaction" includes every debit, credit, cheque, and electronic transfer. High-volume businesses that process hundreds of transactions per month should look for flat-rate plans or unlimited transaction packages.
Business accounts generally support much higher Interac e-Transfer limits than personal accounts — often $25,000 or more per transfer. This is important if you pay suppliers or receive customer payments by e-Transfer.
All major banks offer robust online and mobile banking platforms. Look for features like payroll integration, bill payment, multi-user access for bookkeepers, and API connections to accounting software like QuickBooks or Xero.
Your business banking relationship is often the first place you turn when you need a line of credit, business credit card, or term loan. Banks typically give priority consideration to existing customers with strong account histories.
RBC is Canada's largest bank by assets and offers one of the most comprehensive small business banking platforms. Their eBusiness Plan starts around $6/month for businesses with low transaction volumes. The Digital Choice Business Account is a strong option for online-focused businesses. RBC also offers solid integration with Moneris for payment processing and strong small business lending programs.
TD is known for extended branch hours and strong customer service. Their Business Everyday Banking plans start at about $19/month and include a set number of transactions. TD's online business banking platform is robust, with strong payroll and accounting integration. TD also has one of the better small business lending programs among the Big Five.
BMO's Business Start account is designed specifically for new businesses, with low fees and a streamlined setup process. BMO offers good business credit card options and has strong relationships with the BDC for referral lending. Their online platform integrates well with QuickBooks.
Scotiabank offers competitive business banking packages, particularly for businesses that also need trade finance or international banking services. Their Right Size Account for Business allows you to choose a fee structure based on your transaction volume, making it flexible for growing companies.
CIBC has invested heavily in digital banking infrastructure. Their Smart Business Account includes unlimited Interac e-Transfers and competitive pricing. CIBC also has strong integration with accounting platforms and good small business advisory services.
Several newer players have entered the Canadian business banking space. Wealthsimple has not yet launched a full business account, but options like Relay Financial (operated through Peoples Bank of Canada) offer no-fee business banking with modern digital tools. These accounts are best suited for digital-first businesses with simple banking needs.
Opening a business bank account requires different documentation depending on your business structure:
Here's a realistic look at annual business banking costs for a small business processing 50–100 transactions per month:
Many banks offer a free period (3–6 months) for new businesses. Ask about this when you're opening your account.
Don't overlook credit unions. Canadian credit unions like Desjardins, Meridian, First West Credit Union, and Affinity Credit Union often offer lower fees and more personalized service than the Big Five. They are provincially regulated and deposits are covered by provincial deposit insurance (in most cases, unlimited coverage rather than CDIC's $100,000 per category limit).
Regardless of which account you choose, the most important action is to open it and use it exclusively for business. Pay yourself a salary or owner's draw, and keep every business expense running through the business account. This discipline will save you significant accounting costs at year-end and make CRA compliance far simpler.
Legally, sole proprietors can, but it's strongly discouraged. Corporations cannot — they are separate legal entities and must have their own accounts. Using a personal account creates accounting headaches and can complicate CRA filings.
Several online providers offer free or very low-cost business banking. Relay Financial and some credit unions offer no-fee options. Among the Big Five, BMO's Business Start account and RBC's eBusiness Plan are among the most affordable entry-level options.
It's best practice to open one as soon as you register your business. Initial expenses (incorporation fees, software, equipment) should run through the business account to be deductible.
