Best Startup Accelerators in Ontario: Our 10 Top Accelerators + What to Look For

Startup accelerators (also called business accelerators) are programs that provide startups with mentorship, resources, and networking opportunities to help them grow and succeed. These programs have become increasingly popular in Ontario, with hundreds of accelerators and incubators available to entrepreneurs across Canada.

In this article, we explain what business accelerators are, their pros and cons, and highlight some of the best accelerators in Ontario to help you make an informed decision about which program to join.

What are Startup Accelerators?

A startup accelerator is a program designed to help early-stage businesses grow and succeed by providing them with mentorship, resources, and access to investors. It is a time-limited program that typically lasts between three to six months, during which time the participating companies receive intensive support to help them achieve specific goals and milestones.

Business accelerators are usually run by organizations such as universities, venture capital firms, or government agencies. They are often sector-specific, focusing on industries such as technology, healthcare, or clean energy.

Startup Accelerator vs Business Incubator: Key Differences

Startup Accelerators

  • Ideal for businesses that already have a minimum viable product
  • Help early-stage companies scale quickly 
  • Have a set timeframe, usually lasting several months
  • Provide mentorship and funding

Business Incubators

  • Help entrepreneurs flesh out their ideas
  • Operate on a flexible timeframe
  • End when a business has an idea or product to pitch to investors or consumers
  • Provide office space, mentorship, and networking opportunities

How Do Startup Accelerators Work?

Accelerators provide startups with a range of resources and support services, typically including:

  • Mentorship from experienced entrepreneurs and industry experts
  • Access to investors and funding opportunities
  • Networking events and opportunities to connect with other entrepreneurs
  • Workshops and training sessions on topics such as marketing, sales, and finance
  • Office space and other resources, such as legal and accounting services

Participating companies are typically required to give up a small equity stake in their business in exchange for the support and resources provided by the accelerator. This helps to align the interests of the accelerator with those of the startups it supports, as the accelerator has a vested interest in helping its portfolio companies succeed.

Overall, business accelerators can be a valuable resource for early-stage startups looking to grow and scale their businesses. By providing access to mentorship, resources, and funding opportunities, accelerators can help startups overcome common challenges and achieve success more quickly and efficiently than they might be able to on their own.

    Before joining an accelerator, it’s important to set clear goals and objectives for what you hope to achieve. This can include gaining access to mentorship, networking opportunities, and funding.

    Additionally, some accelerators require a certain level of participation, such as attending weekly meetings or completing specific milestones. Make sure you understand the accelerator’s expectations and requirements before applying.

    • Equity and Funding Terms

    Most accelerators require equity in exchange for participation in the program. The amount of equity varies by accelerator, so it’s important to understand the terms before applying. Additionally, some accelerators provide funding as part of the program. Make sure you understand the funding terms and any additional requirements, such as a demo day pitch or specific milestones, before accepting funding.
