Ottawa's Erica Wiebe claimed gold in the women's 75-kilogram event, and later Korey Jarvis won gold in the men's 125-kilo competition.
Wiebe won all four of her matches, capping her run by defeating Indian wrestler Jyoti by pinfall. She also beat England's Sophie Edwards, Cameroon's Annabel Ali and Nigeria's Blessing Onyebuchi on points.
"To win in a high pressure situation was big," said Wiebe. "I was feeling it today, I was feeling the pressure and I put a lot on myself, but this is what I need going into the next two years I need to continue to win and continue to win in situations like this."
Ali won silver while Onyebuchi took bronze.
"When I won it was emotional," said Wiebe. "This is what I have been thinking about and dreaming about. It was awesome to have that moment for myself, the first time that I did this at a big event," said Wiebe. "I have never had my anthem played so I was thinking about that before I went out there and that is what I was wrestling for today."
Jarvis defeated Rajeev Tomar in the men's 125-kilo final, outscoring the Indian 3-0.
"I didn't get as much offence going as what I would have wanted to," said Jarvis. "I thought I would have been able to move him a lot more, but he is a pretty big guy and pretty solid in his position, but I ended up persevering."
Jarvis was a silver medallist four years ago in New Delhi.
"It was a tight win, but it was too long," he said. "The silver medal in Delhi haunted my dreams, glad I got the gold here."
Tomar took silver, while England's Chinu XXX and Nigeria's Sinivie Boltic took bronze.
Also Tuesday, Jasmine Mian of Barrie, Ont., won bronze in the women's 48-kilogram event, defeating Nigeria's Rosemary Nweke 13-2 in a bronze-medal match.
"I was eager this morning to make that gold medal final. I was a little hesitant and not myself," said Mian. "After I had a loss I woke up and said 'You know what, I am here and have to do the best I can, stop focusing on the outcome and wrestle my match.'"Suggest a correction
