About
EVOLVE Egg Freezing Clinic is Canada's first and only fertility clinic devoted exclusively to egg freezing, operating in the Greater Toronto Area from a flagship downtown location at 655 Bay Street and a Midtown satellite at 36 York Mills Road that opened in 2024. As the dedicated egg-freezing arm of TRIO Fertility, EVOLVE offers elective egg freezing, fertility preservation for medical reasons (in coordination with TRIO), and a structured Pre-Freeze Program led by on-site naturopaths that supports egg quality through diet, supplements, and lifestyle in the months before retrieval. Pricing is published openly: $8,800 per cycle (covering stimulation, monitoring, anesthesia, and retrieval), $5,000–$10,000 for medications depending on protocol, and storage at $2,000 for five years up front or $780 annually.
The clinic is led by Medical Director Dr. Sony Sierra, an REI specialist and immediate past president of the Canadian Fertility & Andrology Society, and a team that includes reproductive endocrinologists Dr. Shirin Dason, Dr. Cassandra Greenberg, Dr. Katharine Phillips, Dr. Arielle Cantor, Dr. Priyanka Patel, and Dr. Chaula Mehta, plus naturopathic support through Conceive Health. EVOLVE is transparent about the Ontario Fertility Treatment Tax Credit and the Medical Expense Tax Credit, partners with Beautifi for financing, and offers a complimentary phone consultation with a nurse plus virtual first physician appointments at the Midtown clinic. Inclusive content explicitly welcomes transgender men exploring fertility preservation before or during hormone therapy, and the patient experience is shaped around individuals making decisions on their own timeline rather than couples seeking IVF.
