Living Organ Donation in Canada — What You Need to Know
A 42-year-old woman in BC learns her brother needs a kidney transplant. After 9 months of assessment — bloodwork, imaging, psychological consultation, ethics review — she's cleared to donate. The surgery goes smoothly. Six weeks later she's back at work, with one fully-functioning kidney and her brother off dialysis for the first time in three years. This is a living donation story Canadian transplant programs see hundreds of times each year.
Living donation is fundamentally different from deceased donation, both medically and ethically. This guide covers what's possible, how the process works in Canada, and what prospective donors should consider.
What can be donated while living
Three types of living donation are routine in Canada:
Kidney donation. Most living donations are kidneys. Humans have two kidneys and can function normally with one. A single kidney typically grows slightly and provides about 70-80% of the original two-kidney function. Recovery from donor nephrectomy is 4-6 weeks for return to most activities.
Partial liver donation. The liver regenerates substantially after donation. A donor gives a segment (typically the left lateral segment for an adult-to-child donation, or the right lobe for adult-to-adult). The remaining liver regenerates to near-normal size within months. Recovery is longer and more complex than kidney donation — typically 8-12 weeks.
Bone marrow / hematopoietic stem cell donation. Less invasive than organ donation. Stem cells can be collected either through bone marrow extraction from the pelvis (under anaesthesia) or, more commonly now, through peripheral blood stem cell collection after several days of medication that mobilises stem cells into the bloodstream. Recovery is days, not weeks.
Partial lung donation. Rare but possible. Two donors each give a lobe of one lung to a single recipient. Used when no deceased donor lung is available for a critically ill recipient.
Pancreas and small bowel living donation is technically possible but very rarely performed in Canada.
Who pays
Canadian living donors generally do not bear medical or significant out-of-pocket costs:
Medical costs: Covered under provincial health insurance for both surgery and immediate post-operative care.
Out-of-pocket costs: Reimbursable through provincial living-donor expense programs — there is no single federal program. Ontario's PRELOD (Program for Reimbursing Expenses of Living Organ Donors) is administered by Ontario Health (Trillium Gift of Life Network); British Columbia, Manitoba, Quebec, and Nova Scotia run their own equivalent programs. These reimburse travel, accommodation, meals, parking, lost wages, and in some cases childcare during the donation and recovery period. Reimbursement caps and specific eligibility vary by province — Ontario's PRELOD, for example, caps lifetime reimbursement per donor.
Long-term costs: No structural insurance issue exists from donation in itself, but donors should review their life and disability insurance before donation to confirm no coverage changes are triggered. (In practice, donation is generally not penalised by Canadian insurers, but reviewing in advance is prudent.)
The medical risks
Living donation is real surgery with real risk:
Kidney donation:
- Perioperative mortality risk: approximately 0.03% (3 per 10,000)[4]
- Major surgical complications: 2-5%
- Long-term: slightly elevated blood pressure risk, modest reduction in kidney function (most donors maintain normal function indicators)
- No reduction in life expectancy in long-term follow-up studies
Liver donation:
- Perioperative mortality risk: approximately 0.2-0.5% (higher than kidney)
- Major surgical complications: 10-15%
- Longer recovery (8-12 weeks typical)
- Long-term liver function generally normal
Bone marrow / PBSC donation:
- Very low procedural risk
- Recovery in days to weeks
- Some bone soreness or fatigue post-procedure
The transplant team provides detailed informed consent documentation specific to the type of donation, the donor's individual risk factors, and the recipient's circumstances.
Directed vs. non-directed donation
Directed donation: The donor specifies a particular recipient. The most common scenario — donating to a family member, spouse, friend, or other person with whom the donor has a relationship. Compatibility (blood type, tissue match for kidney) must be confirmed.
Non-directed (anonymous) donation: The donor gives without specifying a recipient. The donated organ goes to the next compatible person on the waitlist. Canadian programs accept non-directed donors, though they typically apply additional psychological screening to ensure the donor's motivation is well-considered.
Paired exchange: When a donor wants to give to a specific recipient but isn't compatible, paired exchange programs match donor-recipient pairs to enable swaps. For example, Donor A isn't compatible with Recipient A, but Donor A is compatible with Recipient B; Donor B is compatible with Recipient A. The two pairs swap, and both recipients receive transplants. Canada operates the Kidney Paired Donation program nationally through Canadian Blood Services.
The assessment process
Living donor assessment is intentionally slow and thorough. Typical steps:
- Initial screening: Blood type compatibility, basic health screening, completion of an information package
- Medical workup: Comprehensive blood work, urinalysis, imaging (typically CT or MRI for kidney donors), kidney function testing, infectious disease screening
- Compatibility testing with recipient: Tissue typing, cross-matching, antibody screening
- Psychological assessment: Independent evaluation of donor's mental readiness, understanding of risks, motivation, support system
- Ethics review: For some directed donations, a formal ethics review confirms the donation is freely chosen
- Final medical clearance: Anaesthesia consultation, surgical planning
- Informed consent: Detailed discussion of risks, alternatives, and recovery expectations
- Surgery scheduling: Coordinated with recipient's transplant timing
The total process typically takes 4-9 months. The assessment team is structurally separate from the recipient's care team — the donor advocate's job is exclusively to protect the donor's interests.
What donors should consider
Some questions worth thinking through before pursuing donation:
Why am I considering this? Donors who proceed for solid, well-considered reasons (love for a specific person, deeply held value of helping others, considered altruism) typically have positive long-term experiences. Donors who proceed under family pressure or guilt sometimes have worse outcomes.
What if my future health needs my second kidney? Donors do face slightly elevated risk of needing dialysis themselves later in life. Most living donors are not in a high-risk demographic, but this is a real consideration.
What's my support system? Recovery requires 4-6 weeks of reduced activity. Practical support (someone to drive, help with cooking, childcare) makes a real difference.
What if the recipient outcome is poor? Recipient transplant outcomes are generally good but not certain. Some donors find it hard if a recipient experiences rejection, infection, or other complications. Psychological preparation for both outcomes matters.
What if I want to withdraw? Throughout the entire process, withdrawal is honoured and confidential. The recipient is told only that the donation isn't proceeding, not why.
What we focus on at It's Simple Will
It's Simple Will focuses on estate planning rather than living donation directly. But the values that drive Canadians toward living donation — care for family, considered generosity, taking practical action — are the same values that drive thoughtful estate planning.
If you've donated or are considering donation, our will questionnaire helps you document your broader end-of-life wishes alongside your living donation history.

Frequently asked questions
What can be donated while living?
The most common living donations in Canada are kidneys (one of two), partial liver (the liver regenerates substantially), and bone marrow / hematopoietic stem cells. Partial lung donation is possible but rarer. Living donors must be adults capable of informed consent and must meet medical eligibility criteria including overall health, compatibility, and psychological assessment.
Who pays for living donation?
The recovery surgery and immediate post-operative care are covered under the donor's provincial health insurance — the donor does not pay for the medical procedure itself. Out-of-pocket costs (travel, accommodation, lost wages, childcare during recovery) are reimbursable through provincial living-donor expense reimbursement programs — Ontario's PRELOD (Program for Reimbursing Expenses of Living Organ Donors) is the best-known, and British Columbia, Manitoba, Quebec, and Nova Scotia run their own equivalents. There is no single federal reimbursement program; coverage depends on the donor's and recipient's province. The donor typically does not bear out-of-pocket costs.
What are the medical risks?
Living donation involves real surgical risk. For kidney donation, the perioperative mortality risk is approximately 0.03% (extremely low but not zero). Recovery typically takes 4 to 6 weeks for return to most activities, with full recovery longer. Most donors return to normal kidney function with a single kidney. Long-term risks include slightly elevated risk of hypertension and minor reduction in kidney function. Surgical teams provide detailed informed consent before any donation proceeds.
Can I donate to a specific person?
Yes — directed donation to a specific recipient is permitted in Canada when medical compatibility exists. Donors are typically family members, close friends, or others with an established relationship to the recipient. Anonymous (non-directed) donation, where the donor gives without specifying a recipient, is also permitted. Some provinces have paired exchange programs for situations where the donor isn't compatible with the intended recipient but matches someone else who has their own donor.
What is the assessment process like?
Living donor assessment is rigorous and typically takes several months. It includes full medical evaluation (blood work, imaging, organ function tests), compatibility testing with the recipient, infectious disease screening, psychological assessment, and detailed informed consent discussions. The assessment team is structurally independent from the recipient's transplant team to ensure the donor's interests are protected throughout.
Can I change my mind?
Yes. Living donation is voluntary throughout the entire process — donors can withdraw consent at any point up to the moment of surgery. Withdrawal is treated confidentially; the recipient is not informed of the specific reason. This protection exists because the transplant community recognizes that no one should feel pressured to proceed if they have any reservations.
