Ontario’s Top Solar & Storage Companies Today
Ontario remains a national hub for solar manufacturing, EPC, and storage. Below we compare eight Ontario-tied leaders – what they build, where they excel, and which use-cases (home, commercial, utility) they fit best – plus a brief SunRise Power retrospective.
How We Selected These Industry Leaders
To ensure this list highlights credible and proven contributors to Ontario’s renewable energy market, each company was evaluated based on:
- Operational footprint in Ontario (headquarters, facilities, or active projects)
- Proven capacity delivered (measured in MW/MWh of solar or storage)
- Segment strength (manufacturing, EPC, or energy storage specialization)
- Net-metering or utility-scale expertise relevant to Canadian markets
- Safety and compliance record (ESA/CSA certifications and operational reliability)
- Customer and community outcomes, including sustainability impact
Below are the Ontario-based firms leading the way in solar power and renewable energy development today:
- Alectric Renewables – Founded in 2015 in Markham, Alectric has installed over 150 MW of solar PV systems and manages 2.5 GW of projects in development across Canada and internationally.
- Amp Energy – Based in Toronto, Amp is a global energy transition leader with over 14 GW of renewable and battery storage assets, integrating AI and green hydrogen technologies.
- Borea Construction – Operating from Toronto and Saint-Nicolas (QC), Borea has built more renewable projects in Canada than any other contractor, delivering over 7,500 MW of wind and solar power.
- Canadian Solar – Headquartered in Guelph, Ontario, Canadian Solar is one of the world’s largest solar energy manufacturers, shipping over 165 GW of solar modules and 13 GWh of battery storage systems to more than 160 countries.
- Cordelio Power LP – Headquartered in Toronto and owned by the Canada Pension Plan Investment Board, Cordelio manages a 396 MW portfolio of wind and solar projects across Ontario.
- NorthGrid Solar – Established in 2009 in Markham, NorthGrid provides EPC and O&M services for solar and energy storage projects, with 45,000+ systems deployed in 62 countries.
- Otter Energy – With offices in Picton and Etobicoke, Otter has installed over 450,000 solar panels since 2009, helping homeowners and businesses reduce their hydro costs by up to 80% while annually cutting millions of pounds of carbon emissions.
These firms collectively illustrate the breadth of Ontario’s solar cluster: from raw silicon to finished solar panels distributors, to advanced system innovation. In that context, one of the earlier regional leaders was SunRise Power (SunRise Solar) – now defunct – whose history offers both lessons and insights for today’s industry landscape. Today, Ontario’s solar sector is not only advancing manufacturing and construction – it is also powering the province’s fast-evolving digital infrastructure. From financial services to high-demand online platforms, secure data centers increasingly rely on renewable energy to support growth, reliability, and sustainability.
Smart Technologies: Data Centers, Solar Energy & Player Safety in Online Gaming
Ontario’s growing digital economy – including cloud computing, fintech, and the regulated online gaming market overseen by AGCO and iGaming Ontario – relies on secure and always-on digital infrastructure. These platforms operate 24/7, processing high volumes of transactions and player activity. As a result, data centers are transitioning to renewable energy sources for greater reliability and efficiency.
Solar power now supports digital services by helping to:
- reduce the carbon footprint of high-demand computing
- ensure stable and scalable energy supply
- meet ESG standards across Ontario’s tech sector
- lower long-term operational costs for energy-intensive services
In the iGaming industry, sustainability also translates directly into stronger player protection. Resilient, renewables-powered data centers help safeguard encrypted payments, maintain continuous platform uptime, and ensure that responsible gaming tools remain available without interruption. For users comparing the best online casino Ontario options, a look at the regulated digital entertainment sector connects those behind-the-scenes infrastructure standards with real-world considerations, outlining how licensed platforms are evaluated within the province.

Legacy
Though SunRise, Sunris, Sunrie, Unrise, and even Sunsrise were names often seen in searches, all referred to this same innovative solar Ontario firm. The company’s pioneering work in domestic-content solar manufacturing and lean EPCM practices influenced later firms in Canada’s renewable sector. Even experiments like the Sunrise iPad control interface once showcased the brand’s focus on integrating technology and energy – an early vision of the modern smart-grid era.
SunRise Power once embodied the best of Canada’s renewable spirit – bridging innovation, manufacturing, and sustainability. From SunRise solar panels to global collaborations and engineering excellence, the SunRise company left a meaningful footprint in Ontario’s solar history, even though it eventually closed its doors.
While SunRise Power represented the early wave of Ontario’s solar pioneers, the province’s renewable industry continued to evolve through new innovators. Among the companies carrying that momentum forward is Alectric Renewables, a modern developer that has expanded Ontario’s solar reach both at home and abroad.
