Baseball fans turned a World Series rivalry — and heartbreaking loss — into hope for children's health, donating $30K to @sickkids.
This will advance care, research and education for patients and families.
Thank you for hitting it out of the park! ⚾

After 32 years, ED legend Andrea Boysen is retiring from SickKids — leaving a legacy of calm, compassion and mentorship in one of the most unpredictable settings in health care.
This #EmergencyNursesWeek, we celebrate her and all ED nurses for the difference they make every day.

The ED never slows down — and that’s where nurses like Tony shine.
“Working in the ED can be intense and unpredictable, but that’s what makes it so rewarding. We see kids at their worst and get them the care they need.”
Happy #EmergencyNursesWeek to Tony and all ED nurses!

In the Emergency Department, every moment counts.
“We assess, prioritize, and act fast in rapidly changing situations. The ED challenges you, and the team lifts you up,” says Registered Nurse Jillian Koskins.
Celebrating Jillian and all ED nurses this #EmergencyNursesWeek!

Recently I got to chat with @TheEconomist about why @Toronto is the greatest city in the world to invest & build health AI.
