The baby was delivered by Caesarean section Saturday after doctors determined the fetus was viable, the Canadian Broadcasting Corp. reported Tuesday.
The mother, Robyn Benson, had been on life support since having a brain hemorrhage Dec. 28 that left her brain dead. She was five months pregnant at the time.
Benson's 32-year-old husband Dylan announced the birth of his son Monday on his Facebook page.
"Iver is healthy and is the cutest and most precious person I have ever met," Benson wrote.
He also mourned the death of his wife, who died Sunday.
"I miss Robyn more than words can explain," he said. "I could not be more impressed with her strength, and I am so lucky to have known her. She will live on forever within Iver, and in my heart."
Benson has received more than $144,000 in donations to the "Baby Iver" fund he started after his wife was hospitalized and he took leave from work. He said any money left over from paying medical bills would go toward Iver's care and education.
Benson said the baby will stay in the hospital until he is healthy enough to go home.
