Many Canadian patients ask whether undergoing bariatric surgery provides some tax benefits:
Generally, Bariatric surgery — including gastric sleeve, gastric bypass, revisional surgery and others — qualifies as an eligible medical expense under the Canadian Income Tax Act, even when the procedure is performed outside of Canada.
Specific Canadian Tax Code:
- Medical Expense Tax Credit (METC)
- Refundable Medical Expense Supplement on Line 45200.
Quick note on tax years: Returns filed in spring 2026 cover the 2025 tax year. Returns covering the 2026 tax year are filed in spring 2027. The numbers below reflect the most recent CRA-indexed figures published for both years so you can plan accordingly.
Is Bariatric Surgery in Mexico an Eligible Medical Expense?
Yes, the Canada Revenue Agency, CRA, confirms that “medical services outside Canada” are eligible, and that you can “generally claim all amounts paid, even if they were not paid in Canada,” provided the service was performed by a licensed medical practitioner or a public or licensed private hospital in the country where the treatment was received (Canada.ca, Medical Expenses 2025). All of Renew Bariatrics’ bariatric surgeons are double-board certified.
CRA’s own technical interpretations have specifically addressed surgeries performed abroad, noting that “eligible medical expenses are not restricted to those paid in Canada or for medical services provided in Canada” (CRA Technical Interpretation 2020-0851841E5).
What matters for the Canada Revenue Agency:
- The procedure must be performed by a licensed or registered medical practitioner in the country where it is provided.
- The hospital or surgical facility must be public or a licensed private hospital under that country’s laws.
- You must have paid the expense out of pocket and not been reimbursed (by insurance, an employer plan, or anyone else).
- You must keep original receipts, invoices, and a 12-month period ending in the tax year for which you are claiming.
Important Note: Cosmetic or plastic surgery performed solely for appearance (liposuction, body-contouring after weight loss done strictly for cosmetic reasons, etc.) are not eligible. Bariatric surgery, however, is medically necessary treatment for obesity and qualifies in the same way as any other surgery performed by a licensed practitioner.
The Two Credits You Should Know About
1. Medical Expense Tax Credit (METC) — Lines 33099 / 33199
This is the main, non-refundable federal credit available to all Canadians who incur eligible medical expenses. It reduces the tax you owe.
How it works: You claim eligible medical expenses that exceed the lesser of:
- a fixed dollar threshold (indexed annually), or
- 3% of your net income (Line 23600).
The portion above that threshold becomes the base for your credit.
| Tax Year | Fixed Threshold (lesser-of cap) | Federal Credit Rate |
|---|---|---|
| 2025 (filed in 2026) | $2,834 (Canada.ca) | 14.5% |
| 2026 (filed in 2027) | $2,890 (KPMG 2026 Tax Facts) | 14.0% |
What changed for 2026: The federal credit rate for non-refundable tax credits — including the METC — drops to 14.0% (from 14.5%) for the 2026 tax year, in line with the federal government’s reduction to the lowest marginal income tax bracket (KPMG, Federal and Provincial Non-Refundable Tax Credit Rates 2026).
Real Example (2026 tax year): If your net income is $70,000 and you incurred $25,000 in eligible bariatric expenses, 3% of net income is $2,100 (less than the $2,890 fixed cap), so your threshold is $2,100. Your METC base is $25,000 − $2,100 = $22,900. Federal credit = 14.0% × $22,900 = $3,206, before adding the matching provincial credit (rates and thresholds vary — see KPMG’s table for your province).
Pro tip: It’s almost always better for the lower-income spouse to claim the family’s medical expenses, because the 3% threshold will be smaller (Canada.ca, Lines 33099/33199). Couples can also combine all family expenses (you, your spouse/common-law partner, and children under 18) on a single return.
You can also choose any 12-month period ending in the tax year — useful if your surgery, follow-up appointments, and travel costs span two calendar years.
2. Refundable Medical Expense Supplement — Line 45200
This is a refundable credit for lower-income working Canadians, paid out even if you owe no tax. The thresholds have been substantially updated since the original version of this article was written.
| Criteria | 2025 Tax Year | 2026 Tax Year |
|---|---|---|
| Minimum employment / self-employment income | $4,390 (Canada.ca, Line 45200) | $4,478 (TaxTips.ca) |
| Maximum supplement | $1,534 | Indexed annually (≈ $1,560+) |
| Adjusted family net income — full credit up to | $33,294 | $33,960 |
| Adjusted family net income — fully phased out at | $63,374 | $55,449 (per TaxTips); confirm with a tax professional |
| Reduction rate above threshold | 5% of family net income above the lower threshold | 5% of family net income above the lower threshold |
To qualify, all of the following must apply (Canada.ca, Line 45200):
- You entered an amount on Line 21500 (disability supports) or Line 33200 (allowable medical expenses) of your return.
- You were a resident in Canada throughout the tax year.
- You were 18 years of age or older at the end of the tax year.
- You had employment or self-employment income (excluding wage-loss replacement income and excluding losses) above the minimum threshold above.
- Your adjusted family net income is below the upper threshold.
The supplement is calculated as the lesser of the dollar maximum or 25% of the sum of your medical expenses (Line 33200) and disability supports (Line 21500) (Refundable Medical Expense Supplement). It’s a meaningful top-up for working Canadians whose income is modest enough to qualify but who incurred a major expense like out-of-country bariatric surgery.
Travel, Lodging, and Accompanying Person Costs
CRA travel rules apply equally to medical travel inside or outside Canada, provided the equivalent care was not reasonably available closer to home and your route was direct (Knowledge Bureau, Driversnote).
The 40 km rule. If you travelled at least 40 km one way to obtain a medical service unavailable near home, you can claim transportation costs (flights, taxis, buses, trains, mileage if public transit isn’t reasonable).
The 80 km rule. If you travelled at least 80 km one way, you can additionally claim accommodation, meals, and parking during the period of treatment. The CRA’s simplified method lets you use a flat per-kilometre rate and a flat per-meal rate so you don’t have to keep every restaurant receipt — though we still recommend keeping them.
Accompanying person. If a medical practitioner certifies in writing that you are incapable of travelling alone, the travel, accommodation, and meal costs of one attendant who accompanies you can also be claimed as an eligible medical expense (CRA Technical Interpretation 2020-0851841E5). For most bariatric patients flying to Mexico, this certification is straightforward — your surgeon or family doctor can provide it.
For patients flying from Canada to Tijuana, Cancún, or Puerto Vallarta, the 40 km and 80 km tests are obviously easily met — meaning flights, hotel nights related to surgery and recovery, ground transfers, meals, and your support person’s parallel costs are typically all in scope.
What You Can Claim — Bariatric-Specific Checklist
Ask our accounting department for an itemized invoice of your surgery. In addition to the invoice keep reciepts on all of the following – potential – expenses.
- Renew Bariatrics Invoice – Itemized invoice including medications, and transportation
- Medical Supplies if necessary
- Round-trip airfare (you and a certified attendant)
- Hotel during your trip to San Diego or Cancun
- Meals (simplified method permitted)
Items that are not eligible: purely cosmetic add-ons (e.g., elective post-bariatric tummy tuck or breast lift done for appearance only), provincial health-plan premiums in most provinces, and any portion reimbursed by insurance or an employer plan (Medical Expenses 2025).
Documentation: What to Bring Home From Mexico
The CRA routinely audits large medical expense claims. To survive a review, build your file at the time of treatment:
- Itemized invoice from the hospital — surgeon fee, anesthesia, facility, supplies, medications — broken out, on hospital letterhead, with the practitioner’s licence/registration number where possible.
- Proof of payment — credit card statements, wire transfer confirmations, or paid-in-full receipts that match the invoice amounts.
- Surgeon’s letter confirming the diagnosis, the procedure performed, the dates of treatment, and (for the attendant claim) certifying that you required an accompanying person.
- Boarding passes, hotel folios, and ground-transport receipts for travel claims.
The CRA can ask for these documents up to six years after you file. Keep your bariatric file organized and accessible.
Provincial Credits Stack on Top
The METC has both a federal and a provincial component. Most provinces use a similar “lesser of 3% of net income or fixed threshold” structure, with thresholds varying from roughly $1,728 (Quebec) to $2,942 (BC) for the 2026 tax year, and provincial credit rates ranging from about 4% to 21% (KPMG 2026 Tax Facts).
Ontario residents aged 70 or older can also claim a separate refundable Ontario Seniors Care at Home Tax Credit equal to 25% of eligible medical expenses, up to a $1,500 maximum, phased out by 5% of family net income above $35,000 (nil at $65,000) (Raymond Chabot Grant Thornton).
Quebec follows its own rules — Quebec residents should consult Revenu Québec rather than the CRA chart.
A Realistic Worked Example (2026 Tax Year)
Marie, age 42, lives in Mississauga and earns $58,000 net. Her husband earns $95,000. In June 2026 Marie travels to Tijuana for a gastric sleeve. Her costs:
- Surgical package (hospital, surgeon, anesthesia, two nights inpatient): $6,800 CAD
- Round-trip flight Toronto–San Diego (Marie + her husband as certified attendant): $1,400 CAD
- 2 nights recovery hotel in San Diego: $300 CAD
- Ground transfers, meals (simplified method), pre-op bloodwork in Canada, prescriptions: $1,100 CAD
- Total eligible: $9,600 CAD
Marie claims everything on her return (lower net income). Her 3% threshold is 3% × $58,000 = $1,740 (less than the $2,890 cap). Her METC base is $9,600− $1,740 = $7860. Federal credit at 14.0% = $1,100; Ontario credit at 5.05% on the first $13,156 = $427. Total reduction in tax payable: about $1,500.
Her family net income is too high to qualify for the Line 45200 refundable supplement, but if Marie were a single earner at $40,000 net, she would also pick up roughly $1,400–$1,500 from that supplement on top.
Things to Do:
- Referral or written recommendation from your Canadian family doctor or specialist documenting the medical necessity of bariatric surgery.
- Request an attendant certification letter if you’ll be traveling with a spouse, parent, or friend.
- Request an itemized Invoice from Renew Bariatrics staff.
- Pay by wire (required) so you have a clean paper trail.
- Track every travel expense from the moment you leave home until you return.
- Choose your 12-month claim window strategically if your surgery is near year-end, so pre-op and post-op costs fall into the same claim.
- File with a Canadian tax professional experienced in medical expense claims — particularly important the first year, given the audit profile of large METC claims.
Summary
For 2026, Canadian patients traveling to Mexico for bariatric surgery can claim:
- The non-refundable Medical Expense Tax Credit at 14.0% federal (plus provincial), on amounts above the lesser of $2,890 or 3% of net income.
- The Refundable Medical Expense Supplement of up to roughly $1,560 for lower-income working Canadians (income tests apply).
- Airfare, hotels , meals, and an accompanying person’s costs when the trip exceeds CRA’s 40 km / 80 km tests — which is automatic for any flight to San Diego, or Cancun, Mexico.
Combined, these tax credits can save patients several thousand dollars. Be sure to save your receipts and all invoices, so you can present them to a qualified Canadian tax preparer.
