Funding
How Construction Grant Stacking Works in Canada
Funding sources are designed to sit on top of each other, but not without limit and not without changing each other. Here is how the layers combine, what caps the total, and why a grant and a refundable credit are not worth the same after tax.
Direct answer
AEC Benefits is an Ontario group benefits brokerage for construction employers, and we publish this alongside our 2026 grants handbook. Grant stacking is the practice of combining non-repayable capital grants, refundable investment tax credits, and concessional financing on a single construction project. The sources are designed to combine, but total direct government funding is capped by each program agreement, and government assistance received on an asset reduces the cost base on which a tax credit is later calculated.

The layers, from the bottom up
A funded capital project usually has four layers. Private equity or a senior loan carries the largest share. A non-repayable provincial or federal capital grant sits on top of that. A refundable investment tax credit applies as a tax measure on the remaining eligible cost. Concessional financing, where available, replaces part of the conventional debt at a lower rate and a longer term. The layers are not alternatives, and a project that only reaches for one of them is usually leaving the others unclaimed.
Sequence beats shopping
Funding is cumulative but order-dependent. A planning or audit grant produces the technical work that a lender needs for underwriting and that substantiates a later tax credit claim. Skipping the cheap first step to get to the large one usually costs more than it saves, because the large application then arrives without the design readiness reviewers score hardest on. Assemble the stack in the order the programs were designed to be used, not in descending order of dollar value.
The ceiling is real, and it is per agreement
Total combined federal, provincial, and municipal direct funding on a project is capped as a share of total eligible costs. The exact ceiling varies by program, and it is set in the individual contribution agreement rather than by one universal rule. Read the stacking clause in each agreement before modelling a combination, because exceeding it does not simply cap the last grant, it can require repayment of funding already received.
A grant dollar and a credit dollar are taxed differently
This is the part that changes the answer rather than just the arithmetic. A direct capital grant on an asset generally reduces the depreciable capital cost of that asset, which reduces the capital cost allowance claimed against income in later years. A refundable investment tax credit delivers cash and is subject to its own cost-base rules. The practical consequence is that two funding packages with the same headline total can leave a business in materially different positions once depreciation is accounted for, so the comparison should be run with an accountant rather than on headline percentages.
The net capital cost formula
The arithmetic itself is not complicated. Net out-of-pocket capital is gross eligible expenditure, less the sum of non-repayable grants received, less the refundable credit calculated on the remaining eligible cost. The trap is applying the credit rate to the gross figure rather than to the reduced base, which overstates the credit by the rate multiplied by the grant amount. Model the reduction first, then apply the rate.
Decision Signals
Use these signals to decide whether the next step is a quote, a renewal audit, or a deeper plan-design review.
| Situation | Signal | Next Move |
|---|---|---|
| You have modelled a grant and a credit at their headline rates | Government assistance reduces the cost base the credit is calculated on | Recalculate the credit on the reduced base before committing the capital plan |
| You are choosing between a large grant and a large credit | Grants affect the depreciable cost base differently than refundable credits do | Run both packages past your accountant on an after-tax basis, not on headline totals |
| You want to skip the small planning grant | The planning work is what later applications and lenders are scored against | Fund the design and audit stage first even where the dollar value looks trivial |
| You are approaching the stacking ceiling | Exceeding it can trigger repayment, not just refusal of the next grant | Read the stacking clause in each signed agreement before adding another source |

Frequently Asked Questions
Can you combine a federal tax credit with a provincial grant?
Generally yes. A refundable investment tax credit is a tax measure and applies on top of direct grants, but the assistance received reduces the cost base the credit is calculated on, and each program agreement sets a ceiling on total combined direct funding.
What is a stacking limit?
It is the maximum share of total eligible project costs that combined federal, provincial, and municipal direct funding may cover. The exact figure varies by program and is set in the individual contribution agreement rather than by one universal rule.
Does a grant reduce my tax credit?
It reduces the base the credit is calculated on. Government assistance received on an asset comes off the capital cost before the credit rate is applied, so the two combine on a reduced base rather than at their full headline rates.
What happens if I exceed the stacking limit?
That depends on the agreement, but the consequence is often more serious than simply being refused the next grant. Contribution agreements commonly require repayment of funding already advanced where the stacking clause is breached, which is why the clause is worth reading before adding a source.
