How to Start a Business in London, Ontario
Thinking of starting a business in London? This comprehensive guide walks you through every step — from choosing the right business structure and registering with ON authorities to securing licenses, finding funding, and building a winning market strategy. Get expert guidance from Ali Sedighi, a seasoned business consultant who has helped 200+ Canadian entrepreneurs launch and grow successful ventures.
Step 1: Choose Your Business Structure
The first major decision for your London startup is selecting the right legal structure. Your choice affects everything from personal liability and tax obligations to your ability to raise capital and sell the business later.
In Ontario, you can operate as a sole proprietorship by registering your business name with the Ontario Business Registry. Partnerships and corporations are also registered through the same OBR portal. Incorporating in Ontario creates a separate legal entity, limits personal liability, and can offer tax advantages — especially important for London businesses planning to scale or bring on investors. Ontario corporations must file annual returns and maintain a registered office address within the province.
Many London entrepreneurs start as sole proprietors and later incorporate as their revenue grows and liability exposure increases. Ali Sedighi helps you evaluate which structure aligns best with your business model, risk tolerance, and long-term goals in the Ontario market.
Step 2: Register Your Business
Once you have selected your business structure, the next step is to formally register your business. In Ontario, this is done through the Ontario Business Registry.
The Ontario Business Registry (OBR) is the one-stop portal for registering, incorporating, and maintaining a business in Ontario. Entrepreneurs in London can register a sole proprietorship, general partnership, or incorporate provincially through this platform. You will need a valid London business address and a NUANS name search report for incorporation.
At the municipal level, the City of London may require a separate business licence for operating within city limits. Here is what you need to know about London-specific registration requirements:
- London Business Licence: Most businesses operating in London require a municipal business licence, which must be renewed annually. Check with London City Hall for specific zoning and licence requirements applicable to your industry.
- CRA Business Number: Register for a federal Business Number (BN) and set up GST/HST, payroll, and corporate income tax accounts through the Canada Revenue Agency.
- Provincial Tax Registration: Depending on your structure, you may need to register for ON provincial sales tax (HST through the federal system) separately.
Ali Sedighi streamlines the entire registration process for London entrepreneurs, ensuring all federal, provincial, and municipal requirements are properly addressed.
Step 3: Obtain Necessary Licences & Permits
Beyond the basic business licence, London businesses may require additional permits depending on your industry, location, and business activities. Failing to secure the right permits can result in fines, closure orders, or legal disputes.
The City of London has specific bylaws regulating signage, noise, health and safety, fire codes, zoning, and waste disposal. If you are opening a retail shop, restaurant, manufacturing facility, or home-based business in London, familiarize yourself with the municipal development permit and building permit requirements applicable to your location.
- Food Service: London restaurants, cafes, and food trucks need health permits from the local public health unit, plus fire inspections and liquor licences where applicable.
- Trades & Construction: Electricians, plumbers, HVAC technicians, and general contractors in London need Ontario College of Trades and municipal building permits for work performed.
- Professional Services: Lawyers, accountants, engineers, and other regulated professionals must be licensed by their respective Ontario governing bodies before offering services in London.
- Home-Based Business: Many London entrepreneurs start from home. Check London municipal zoning bylaws for restrictions on client visits, signage, parking, and the percentage of your home usable for business purposes.
- WSIB Ontario Registration: If you plan to hire employees in London, you must register with WSIB Ontario for workers compensation coverage, which is mandatory in Ontario.
Navigating the full permit landscape can be overwhelming. Ali Sedighi helps London entrepreneurs identify every required licence, complete the applications correctly, and avoid costly delays in launching their business.
Step 4: Secure Funding & Access Grants
Securing adequate funding is one of the biggest challenges for London startups. Whether you are bootstrapping or seeking external financing, knowing which programs are available at the federal and provincial levels can make the difference between a stalled idea and a thriving business.
At the federal level, all Canadian businesses — including those in London — can access programs such as the Canada Small Business Financing Program (CSBFP), which helps secure up to $1 million in loans through participating banks, and the Business Development Bank of Canada (BDC), which provides loans, venture capital, and advisory services. The Scientific Research and Experimental Development (SR&ED) tax credit program also provides significant relief for London companies investing in innovation.
At the provincial level, Ontario offers several targeted funding programs for London entrepreneurs:
- Ontario Innovation Tax Credit: Refundable tax credit for Ontario corporations conducting R&D, applicable to ${cityName} tech and manufacturing startups.
- Eastern Ontario Development Fund: Provides grants and loans to businesses in Eastern Ontario for expansion, productivity, and innovation projects.
- FedDev Ontario: Federal economic development agency offering interest-free loans and grants for Southern Ontario businesses in ${cityName} and surrounding areas.
- Canada-Ontario Job Grant: Covers up to two-thirds of training costs for new and existing employees at ${cityName} businesses.
Additionally, London entrepreneurs can explore private financing options including bank loans, angel investors, venture capital, and crowdfunding. Ali Sedighi helps London startups build compelling business plans and funding applications that meet lender and grant reviewer expectations.
Step 5: Market Research in London
The London market benefits from Ontario's status as Canada's economic engine, with diverse industries including finance, technology, manufacturing, and professional services. Conducting thorough market research in London means examining the local demographic profile, consumer spending habits, competitor analysis, and regulatory landscape. Use tools like Ontario's Open Data catalogue, Statistics Canada census data, and London municipal economic development reports to validate your business idea. Identify unmet needs in the London market, evaluate barriers to entry, and size your total addressable market before making significant investment decisions.
Supply chain logistics, workforce availability, and local business networking opportunities are equally important factors to assess before launching your London business. Organizations like Ontario Small Business Enterprise Centres provide free or low-cost workshops, mentorship, and networking events that connect you with other London entrepreneurs and potential partners.
