Homan's team began the 2016–17 season by winning their first event, the 2016 AMJ Campbell Shorty Jenkins Classic. They then won the 2016 Canad Inns Women's Classic the following month. A week later, the team lost in the final of the 2016 Masters of Curling against the Allison Flaxey rink. A month later, they lost to Jennifer Jones in the final of the 2016 Canada Cup of Curling. The rink lost 2 games in the round robin of the 2017 Ontario Scotties Tournament of Hearts, finishing second in the round robin behind Jacqueline Harrison. They won both their playoff matches, including defeating Harrison in the final, qualifying the team to represent Ontario at the 2017 Scotties Tournament of Hearts. In the final, Team Homan defeated Manitoba's Michelle Englot to win the Scotties, her third Scotties title in four years. Both teams went 10–1 in the round robin, with Homan's lone loss against Englot. Englot beat Homan once again in the 1 vs. 2 game, then Homan beat Northern Ontario's (Krista McCarville) in the semi-final to force the re-match against Englot in the final. At the 2017 world championship in Beijing, Homan's rink became the third team in tournament history to go unbeaten in round-robin play, joining fellow Canadian Colleen Jones from 2003 and Sweden's Anette Norberg from 2005. She went unbeaten right to the end, the first team to do so, winning the gold medal by beating Anna Sidorova (for the 3rd consecutive time, with wins in the round robin, 1 vs. 2 playoff game, and final) 8–3 for the gold medal, her first world title and completing her medal set at worlds. The Homan rink finished the season by winning the 2017 Humpty's Champions Cup. In mixed doubles, Homan and partner John Morris were runners-up at the 2017 Canadian Mixed Doubles Curling Championship, losing to Joanne Courtney and Reid Carruthers in the final.
