Questions

How many clean energy programs for businesses and corporations are open right now?

Of the 41 clean energy programs for businesses and corporations in our database, 20 are open or ongoing and 2 take applications only in intake windows. The rest are closed, paused or of unknown status, so they are not ranked on this page. Counts reflect our last check on Oct 28, 2026; programs can change without notice.

What is the largest published amount among these programs?

Save on Energy XLerate publishes the largest figure on this page, shown as "Up to $15M". Published figures are program maximums, caps or limits, not what an applicant should expect to receive; many programs pay a share of eligible costs and amounts depend on your project and eligibility.

Which clean energy programs for businesses and corporations rank highest?

Right now the top three by our score are Save on Energy Instant Discounts Program (58, Top pick), Save on Energy Retrofit Program (46, Strong), Electric Vehicle Affordability Program (45, Strong). The score combines the size of the published amount, how much work an application takes, how likely an eligible applicant is to succeed and how many people qualify.

Do I have to pay this money back?

It depends on the program. Grants and incentives are generally not repaid, loans always are, and some contribution agreements are partly or fully repayable, so read the terms of each program. Among the 20 open or ongoing programs here, 3 are in our Grants category, 0 are loans and 17 are other incentives such as tax credits and rebates.

Are these federal or Ontario programs?

10 of the 20 open or ongoing programs here come from the federal government and 10 from the Ontario government. Both levels can usually be combined, but many programs have stacking rules that cap total government funding for the same costs, so check them before you apply.

Is this an official government website?

No. Grants & Loans Finder is an independent research tool. Each program page links to the official source, and applications are always made with the government agency or lender that runs the program.
