My Story

12 Aug 2026

Seventeen years ago, we received a phone call from OTMH. “We have your son’s scan results and the doctor wants to send you to SickKids tonight…… Bring a bag to stay overnight…… Yes, you can stay with him.” My body trembled. For a few previous weeks, I felt that Robert’s headaches and nausea were caused by a brain tumour; that phone call more or less confirmed it. The next day, he had an MRI and was prepped for surgery. Less than 48 hours later, the tumour was removed. We spent the next 10 years in and out of SickKids Toronto for MRIs and visits with doctors; Robert was always clear. He was one of the lucky ones.

For the second year, I am taking part in the Great Cycle Challenge to fight kids’ cancer. My family is grateful for the support that we had; we want to do our part to make sure it is there for others.

Thank you.

“Thank you so much for your generosity and support for SickKids and Cancer research. When R is was the hospital, we were scared parents but we didn’t worry. Medical expenses were covered, SickKids was a leader in child medicine and our neuro-surgeon was a world leader in brain cancer research for kids. Donations like yours mean that other parents and their families are able to have faith in the hospital and all of the good that it does. Thank you.”
