How to stack grants forup to $48,000 in combined funding.
Most Ottawa families leave money on the table — not because they don’t qualify, but because they don’t know which programs can be combined, in what order, with what documentation. This guide lays out the complete strategy: seven programs, when each applies, and how to sequence them correctly.
Stacking is not a loophole. It is explicitly permitted by the CRA and program administrators, provided the rules are followed. The rules are what this page explains.
The seven programs that stack
Each row links to the full program page. Review eligibility carefully — some are income-based, some are service-linked, and the timing rules matter as much as the dollar amounts.
| Program | Amount | Type | When to apply | Income test |
|---|---|---|---|---|
| HATC → | Up to $3,000 | Federal tax credit | After work (tax return) | No limit |
| MHRTC → | Up to $7,500 | Federal refundable credit | After work (tax return) | No limit |
| Ontario Renovates → | Up to $20,000 | Grant + forgivable loan | Apply BEFORE work | Low-moderate |
| HVMP → | Up to $15,000 | Provincial grant | Apply BEFORE work | Low-moderate |
| ADP → | 75% of device cost | Provincial equipment funding | Apply BEFORE purchase | No test |
| VIP → | Up to $7,729/year | Federal veteran benefit | Apply BEFORE work | Service-linked |
| METC → | ~15-20% of expenses | Federal tax credit | After work (tax return) | No limit |
What stacks and what doesn’t
- •HATC + any provincial grant. CRA confirms HATC is not reduced by provincial assistance, forgivable loans, or other grants.
- •HATC + MHRTC on the same project. Split expenses: accessibility-specific items under HATC, broader suite construction under MHRTC.
- •HATC + METC on the same expense. Explicitly permitted — same dollar can be claimed under both tax credits.
- •Ontario Renovates + HATC. Receive the $20,000 Ontario Renovates benefit AND claim HATC on eligible expenses.
- •HVMP + Ontario Renovates on different items. Different line items in the same overall project can use different programs.
- •ADP + HATC. Federal HATC applies to your 25% out-of-pocket share of an ADP device.
- •HVMP + ADP on the same item. If ADP funds a stair lift, HVMP will not pay for that same stair lift — but HVMP can cover the related structural work.
- •HVMP + VAC + WSIB on the same item. You cannot receive funding from multiple sources for the identical expense.
- •Work done before approval. Ontario Renovates and HVMP both require written approval BEFORE construction — any pre-approval work is fully ineligible.
- •Two MHRTC claims per qualifying individual. Only one MHRTC claim per senior per lifetime. But two separate seniors in one family can each trigger their own claim.
- •Non-itemized invoices. If your contractor provides one line for the whole project, tax credits become very difficult to claim separately. This is a documentation problem, not a legal one.
Three families, three stacking strategies
Low-income senior in Nepean — bathroom renovation
Mary, age 74, lives alone on a fixed income. She needs a walk-in shower, grab bars, and a comfort-height toilet. Total project cost: $22,000. She qualifies for Ontario Renovates based on income.
Mobility impairment in Kanata — multi-room accessibility project
Robert, age 58, has multiple sclerosis. His family wants to install a stair lift, widen doorways, and convert the main bathroom for wheelchair access. Total project cost: $35,000. Moderate household income. Robert qualifies for HVMP.
Multigenerational home in Barrhaven — building a suite for mom
Jennifer (age 45) is converting her unfinished basement into a self-contained suite for her 76-year-old mother. The suite includes framing, electrical, a full kitchen, bathroom, and bedroom. She adds accessibility features: zero-threshold shower, grab bars, widened doorways. Total cost: $55,000. Middle-income household — Ontario Renovates doesn’t apply.
The 5-step stacking strategy
Order matters. Apply in this sequence to maximize combined funding and avoid disqualifications.
Assess eligibility for income-based provincial programs first
Ontario Renovates and HVMP have the longest approval timelines (8-16 weeks) AND require approval BEFORE work begins. Check eligibility and start these applications first. If you qualify, this unlocks the largest grant dollars and sets your overall project timeline.
Specify ADP-funded equipment during design
If the project includes a stair lift, ceiling lift, or power wheelchair, these come under ADP — not HVMP. Get the OT or PT assessment, authorize the device, and select an ADP-registered vendor during design so installation aligns with the broader renovation.
If applicable: initiate VIP application for veterans
If the qualifying individual is a veteran, open the VIP application concurrently with provincial applications. VIP requires VAC case manager review and has its own approval cycle. Coordinate with provincial programs to avoid duplicate funding for the same item.
Complete work with itemized invoicing
Once all pre-approvals are in place, renovation proceeds. Critical: every invoice must separate accessibility-specific work (HATC/METC-eligible) from general construction (MHRTC-eligible if suite, not eligible otherwise). Still at Home invoices in this format as standard practice.
Claim all applicable federal tax credits on your return
At tax time, claim HATC on line 31285, MHRTC on line 45355, and METC on lines 33099/33199. The same eligible expense can appear under HATC and METC. Forgivable loans and provincial grants do not reduce HATC. Most tax software handles this — but provide your accountant with the itemized invoice summary we prepare.

This page is educational. Eligibility for any specific program depends on your individual circumstances. Tax credits should be confirmed with a qualified accountant before filing. Grant program rules change — always verify current eligibility with the administering body. Still at Home will identify the programs you qualify for during your free assessment and verify current rules at that time.
