Ontario Business Banking: What You Need to Know

Ontario is Canada's most densely populated province for small businesses — over 400,000 small and medium enterprises operate here. Whether you're running a consulting practice in Toronto, a retail shop in London, or a trades company in Hamilton, your choice of business bank account directly impacts your bottom line and CRA compliance posture.

Ontario-Specific Considerations

• HST collection: Ontario charges 13% HST. Once you exceed $30,000 in annual revenues, you must register for an HST number and collect HST on most goods and services. A dedicated business account makes HST remittance tracking simple.
• Ontario Business Registry: When you register a business name with the Ontario Business Registry, your bank will require your Master Business Licence or Business Name Registration to open a business account.
• Employer Health Tax (EHT): Ontario businesses with payroll over $1 million must pay EHT. Your business account will be used for CRA payroll remittances.
• Municipal licensing: Toronto, Mississauga, and Ottawa businesses may require city-specific business licences — your bank may ask for these when opening an account.

Meridian Credit Union — Ontario's Local Business Banking Alternative

Meridian is Ontario's largest credit union with over 100 branches across the province. Their business banking offering competes directly with the Big 5:

• Business chequing accounts from $0–$15/month with competitive transaction bundles
• Business Visa credit cards with cash back
• Business loans and lines of credit with local underwriting
• CDIC coverage up to $100,000 on eligible deposits
• Member profit-sharing via annual rebates

Meridian's branch density across Ontario — particularly in mid-sized cities like Hamilton, London, Kitchener-Waterloo, and Windsor — makes it a strong choice for businesses that need in-person service without Big 5 fees.

Opening a Business Account in Ontario — Step by Step

Step 1: Choose Your Business Structure

Are you a sole proprietor, partnership, or corporation? This determines which documents you need and which accounts are available to you.

Step 2: Register Your Business

Register a sole proprietorship or partnership through the Ontario Business Registry at ServiceOntario. Incorporate federally (Corporations Canada) or provincially (Ontario Business Registry). Get your CRA Business Number (BN) when you register.

Step 3: Gather Your Documents

• Government-issued photo ID
• Master Business Licence (sole prop / partnership) or Certificate of Incorporation
• CRA Business Number
• Corporate resolution if incorporating

Step 4: Open the Account

EQ Bank and KOHO can be opened entirely online in under 15 minutes. Big 5 banks may require a branch appointment or video call for account verification.

HST Savings Strategy for Ontario Businesses

Many Ontario business owners make the mistake of spending HST they've collected before the remittance deadline. A proven strategy is to open a secondary savings account and immediately transfer all HST collected into it. EQ Bank Business Account pays 3.5%+ interest on such a savings buffer — so your HST reserve actually earns money while it waits to be remitted to CRA.

Ontario businesses typically remit HST either monthly, quarterly, or annually depending on their annual revenue. The quarterly remittance cycle is most common for businesses in the $30,000–$6,000,000 revenue range.
