As Ontario grapples with U.S. tariffs and ongoing economic uncertainty, the province’s 2025 budget and fiscal plan focuses on providing support to workers and businesses through new and enhanced measures to develop the energy sector and stimulate infrastructure and home-building.
The $232.5 billion budget, presented by provincial Finance Minister Peter Bethlenfalvy, projects a $14.6 billion deficit in 2025-26—a drastic increase from the government’s previous estimates in last year’s budget and the fall economic statement. This is due to a renewed focus on spending to respond to the changing economic environment.
Here are some of the major takeaways from Ontario Budget 2025.
Corporate tax measures
Deferring select Ontario-administered taxes
Ontario Budget 2025 reaffirms an earlier proposal that, from April 1, 2025 to Oct. 1, 2025, businesses paying taxes under 10 of Ontario’s business-focused tax programs can defer payments for taxes owed without incurring any interest and penalties.
Ontario businesses must file their tax returns on time during this period.
Enhancing and expanding key manufacturing credit
The new budget outlines proposals that would both expand and enhance the Ontario Made Manufacturing Investment Tax Credit (OMMITC).
Currently, the OMMITC is a 10 per cent refundable corporate income tax credit for Canadian-controlled private corporations (CCPCs) making eligible investments in Ontario.
Eligible investments include expenditures for constructing, renovating or acquiring buildings used for manufacturing or processing—as well as machinery and equipment used in the manufacturing or processing of goods in the province.
The new proposals include:
- Temporarily increasing the current OMMITC rate from 10 per cent to 15 per cent, applicable to CCPCs that make eligible investments in property that becomes available for use between May 15, 2025 and Jan. 1, 2030.
- Expanding the eligibility of the OMMITC to non-CCPCs that have a permanent establishment in Ontario and make eligible investments between May 15, 2025 and Jan. 1, 2030. The proposed OMMITC for non-CCPCs would be non-refundable but could be carried forward up to 10 subsequent taxation years.
- Enhancing the integrity of the OMMITC by requiring repayment of the credit if relevant capital property is sold, converted to a non-manufacturing or processing use, or if certain assets move out of Ontario within five years.
Ontario presented these proposals with the goal of encouraging future investment in the province’s manufacturing industry—including from corporations that may be controlled by non-residents. This signals a policy intent to make Ontario more attractive for foreign capital investment.
Introducing a rail maintenance credit
The Ontario Shortline Railway Investment Tax Credit (OSRITC) is a proposed refundable corporate income tax credit for capital and labour expenditures related to railway maintenance.
If approved, the refundable tax credit of 50 per cent could represent a robust incentive for eligible corporations to invest in the maintenance of Ontario railways at a time when building and maintaining infrastructure is critical.
According to the new budget, the OSRITC would be:
- Applied at a rate of 50 per cent for eligible railway-related maintenance expenditures between May 15, 2025 and Jan. 1, 2030—limited to $8,500 per track mile in Ontario.
- Eligible for corporations licensed provincially under the Shortline Railways Act or federally under the Railway Safety Act, excluding urban rail transit systems and industrial railways.
- Available in respect to eligible investments including capital investments in depreciable property—specifically Classes 1, 3, or 13—for capital cost allowance purposes and labour expenditures directly related to railway track maintenance performed by Ontario residents in the province.
Individual tax measures
Introducing a fertility treatment tax credit
Effective Jan. 1, 2025, the provincial government will offer the new Ontario Fertility Treatment Tax Credit (OFTTC) to support individuals with eligible medical expenses related to fertility treatment for conceiving a child.
The OFTTC will be a refundable personal income tax credit equal to 25 per cent of eligible expenses, up to a maximum of $20,000, resulting in a maximum annual credit of $5,000.
Expenses related to fertility treatment, fertility preservation and surrogacy in Canada will be eligible, provided they are paid by the individual or their spouse or common-law partner. The OFTTC will be available in addition to the existing non-refundable federal and Ontario medical expense tax credits.
Supporting affordable rental housing
As part of Ontario’s broader goal of increasing housing supply, municipalities will be allowed to reduce property tax rates by up to 35 per cent for eligible affordable rental housing units beginning in 2026.
The province also eliminated the 13 per cent HST on qualifying new purpose-built rental housing as part of its efforts to support affordable rental housing.
As a result of these measures, taxpayers investing in or operating eligible affordable rental housing in Ontario will now have a lower overall tax burden.
Other tax measures
Introducing updates to the gasoline and fuel tax framework
To provide relief to individuals and businesses, the Ontario government proposes:
- Introducing new legislation to permanently keep gasoline and diesel tax rates at nine cents per litre. The reduced rates introduced in July 2022 were set to expire in June 2025.
- Eliminating the tax on propane used in licensed road vehicles starting July 1, 2025.
If enacted, these measures could reduce compliance costs and be particularly beneficial to households and small businesses.
Upcoming alcohol tax and mark-up changes
The province will implement the following changes, effective Aug. 1, 2025, to modernize the liquor market and support local producers:
- The spirits basic tax will be reduced from 61.5 per cent to 30.75 per cent.
- Microbrewers will benefit from a reduced beer tax rate of 17.98 cents per litre for draft beer and 19.88 cents per litre for non-draft beer.
- The Small Beer Manufacturers’ Tax Credit, a refundable corporate tax credit, will be amended to align with new tax rates.
Ontario Budget 2025 also proposed increasing the LCBO wholesale discount rate for beer, wine, cider, spirits and ready to drink (RTD) beverages from 10 per cent to 15 per cent, as well as reducing LCBO mark-up rates for ciders, wine-based RTD beverages and spirit-based RTD beverages.
Enhancing digital tax services for businesses
The new budget outlines Ontario’s plan to enhance the provincial tax system by simplifying processes, expanding digital services and reducing compliance costs for businesses through ongoing updates and improvements.
This includes delivering digital services to help businesses meet their tax responsibilities, such as enabling secure payment processes and the ability to manage tax accounts from any device.
