Fertility clinics in Toronto for recurrent implantation failure (RIF)
The small set of Toronto and GTA clinics that publish RIF experience — and how to judge a workup when the diagnosis itself has no agreed definition.
Recurrent implantation failure is the diagnosis patients receive after the hardest kind of IVF experience: good-quality embryos, transferred repeatedly, that don't implant. There is no universally agreed definition — most clinicians use something like failure after two to three transfers of good-quality embryos — and that fuzziness matters, because it means the workup and the treatment vary more between clinics than for almost any other diagnosis. The serious questions divide into two: is this an embryo problem (aneuploidy that PGT-A would catch), or a uterine problem (an undetected cavity issue, chronic endometritis, the timing of the implantation window, or — most contested — immune factors)? Dedicated RIF programs are genuinely rare in the GTA; only three clinics in our directory publish recurrent implantation failure in their conditions-treated information, which is why this page's list is short. Markham Fertility Centre's medical director lists RIF among her clinical focus areas, and CReATe Fertility Centre publishes one of the stronger reproductive-immunology programs in the city. If you've had repeated failed transfers, the clinic conversation you want is a structured one — what's been ruled out, what testing comes next, and which interventions actually have evidence behind them — not a shrug and another identical transfer.
Inclusion: clinic publishes recurrent implantation failure (RIF) in its conditions-treated or sub-specialty information. Dedicated RIF programs are rare — only three GTA clinics currently meet this bar, so this list is deliberately short rather than padded with clinics that merely offer embryo transfer.

How to pick a Toronto clinic for recurrent implantation failure
Start with the structure of the workup. A serious RIF evaluation looks at both sides of the equation: the uterus (hysteroscopy or saline sonogram to rule out polyps, adhesions, and cavity distortion; testing for chronic endometritis) and the embryos (a review of your transfer history, embryo grading, and whether PGT-A has established that euploid embryos are actually failing). Failing two transfers with untested embryos in your 40s is statistically unremarkable; failing multiple euploid transfers is a different problem. A clinic that distinguishes between those two situations before prescribing anything is the clinic you want.
Second, probe the add-on policy. RIF is where fertility medicine's most contested interventions live: endometrial receptivity testing (ERA), intralipid infusions, IVIG, steroids, endometrial scratching. The evidence for most of these is weak or mixed, and a good clinic will say so plainly — offering selected options within honest counselling rather than selling the full menu. A small number of GTA clinics also publish endometrial testing capabilities; Generation Fertility, for instance, lists endometrial microbiome analysis. Ask what evidence supports each recommendation, what it costs, and what the clinic would do if it were their cycle.
Finally, ask about the exit ramp. After repeated failures, the options are: change the protocol, change the embryo strategy (PGT-A, a fresh banking cycle), change the lab, or change the plan entirely (donor eggs, surrogacy in rare uterine-factor cases). A clinic that can articulate when it would recommend each of those — including sending you elsewhere — is being honest about the limits of repeating the same transfer and hoping.
- What does your RIF workup include beyond the standard infertility panel?
- Do you test for chronic endometritis, and how?
- When do you recommend ERA or endometrial receptivity testing — and what evidence do you cite?
- What is your policy on immune therapies like intralipids or IVIG for RIF, and what does the evidence say?
- Given my transfer history, would you recommend PGT-A on my next cycle?
- At what point would you recommend changing labs or getting a second opinion rather than repeating the same transfer?
Frequently asked questions
Which Toronto fertility clinics treat recurrent implantation failure?
+
Only three GTA clinics in our directory publish RIF experience — dedicated programs are rare. Markham Fertility Centre's medical director lists RIF among her focus areas, and CReATe publishes a reproductive-immunology program. The list below filters our directory to clinics with published RIF experience.
What counts as recurrent implantation failure?
+
There's no consensus definition. Most clinicians use failure after two to three transfers of good-quality embryos; some require euploid (PGT-A-tested) embryos before applying the label. The definition matters less than what it triggers — a structured workup of the uterus and the embryo strategy, rather than another identical transfer.
Do immune treatments for RIF actually work?
+
The evidence is contested. Intralipids, IVIG, and steroids lack strong randomized-trial support for unselected RIF patients, and professional societies don't recommend them routinely. Some clinics offer them within honest counselling for selected cases. Ask any clinic proposing immune therapy what evidence supports it and what it costs.
Is the ERA test worth it for implantation failure?
+
The evidence is mixed. ERA aims to find your personal implantation window, but recent trials haven't shown a clear benefit for most patients, and it adds cost plus a mock cycle. It's most defensible after repeated euploid-transfer failures. Ask your clinic when they do — and don't — recommend it.
Will OFP funding cover another cycle after implantation failure?
+
The Ontario Fertility Program funds one IVF cycle per lifetime, including transfers of embryos created in that cycle. If your funded cycle's embryos are exhausted, subsequent retrievals are private-pay — typically $13,000–$20,000 plus medications. PGT-A, often discussed for RIF, is an out-of-pocket add-on regardless of funding.
