Boxing promoter Yvon Michel had tweeted earlier Sunday morning that Stevenson was in critical condition in intensive care.
‘We fear he has a concussion… This is very worrisome,’ Michel said.
The boxer’s fiance, Simone God, said she was at the hospital supporting her partner.
‘He’s a champion, he’s a fighter, he’s going to fight this,’ she said, according to Boxing Scene.
‘We’re partners in life and we’re partners in business. He’s resting right now, showing good signs, and we’re hoping for the best. I have faith that he’s going to be okay.
‘We have good people here, we have support, and we’re trying to keep it together for Adonis and to stay strong for our baby, Adonia.’
Stevenson was making his 10th title defense since winning the belt against Chad Dawson in 2013.
It was his first loss since 2010 and the first in Canada.
Gvozdyk, 31, was fighting in Canada for the first time.
Stevenson was ahead on two of the judges’ card and tied on the third when he was stopped.

Stevenson fell early in the third round after getting hit by Gvozdyk but referee Michael Griffin said it was a slip.
In the sixth round, Stevenson threw more punches to the body, which is something that he rarely does. He hit Gvozdyk in the abdomen and shook him, causing Stevenson to finish the round strongly.
Stevenson controlled the center of the ring for part of the match, but in the 10th round Gvozdyk finished with a series of blows that seemed to motivate him for the 11th round.
Gvozdyk continued with his series of flurries that got Stevenson in the ropes in the middle of the 11th, before sending the Canadian to the canvas with three solid right punches.
On the undercard, Montreal’s Oscar Rivas unanimously outpointed Brazil’s Fabio Maldonado to retain the NABF heavyweight title.
