On Friday, July 11, 2025, Ha Vu Voisin passed away at the age of 56, after a courageous 13-year battle with a complex and rare chronic lung disease. She was surrounded by the love of her family at her residence in Mississauga.

Born in Vietnam, Ha earned a Bachelor of Arts from Ha Noi University before immigrating to Canada, where she later achieved a Master of Business Administration from the University of Windsor in Ontario.

A devoted mother of two and a loving wife of 18 years, Ha was committed to her family. She navigated the challenges of her illness with incredible strength and grace, all while devoting her energy to raising her children. Ha also nurtured a vast network of friendships across the globe, building powerful, lasting bonds that transcended distance and time.

Ha had a passion for life’s simple pleasures. She found joy in her hobbies, which included cooking delicious meals, tending to her garden, watching art films, knitting, and her love of makeup artistry.

Ha was a dedicated participant in a research study for over 10 years to advance the understanding of rare lung diseases. Her contributions allowed NIH in the US, along with their partners at UHN in Canada, to gain valuable insights into not just lung complications, but how complex organ interactions can influence disease progression.

The family wishes to extend their heartfelt gratitude to the medical professionals and institutions that provided exceptional care and support throughout her journey, particularly honoring the efforts and relentless advocation of Dr. Theadore Marras of Toronto Western Hospital (UHN). Special thanks also to Dr. Kevin Fennelly, Dr. Daniel Goldstein, the NIH (NHLBI), the University Health Network in Toronto, and the compassionate care from Natrecia (PSW), Sarah (RN), and Dr. “M” (MD). The family is also grateful for the spiritual guidance of the Linh Son Temple in North York.

Ha is now reunited with her predeceased father, Thai Vu, and grandmother, An Nguyen.

Family and friends are invited to a funeral service on Tuesday, July 15, 2025, at St. John’s Dixie Cemetery and Crematorium (737 Dundas St E, Mississauga). Visitation will be held from 1:00 PM to 2:00 PM, followed by Buddhist prayers from 2:00 PM to 3:00 PM. A private cremation for the immediate family will follow.

Afterwards, all are welcome to join the family for refreshments at a nearby Vietnamese restaurant. Location details will be provided at the service.

In lieu of flowers, donations in Ha’s memory may be made to the United Health Network, Toronto, directed to Research. Flowers may also be sent to St. John’s Dixie Cemetery and Crematorium by 12:00 PM on Tuesday for those who prefer that option.

Memories and notes of condolence may be shared at Basic Funerals.
