The 2016–17 curling season was one of Courtney's best season to date. Her team began the season winning their first event, the 2016 AMJ Campbell Shorty Jenkins Classic. They followed this up by winning 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 in the final of the 2016 Canada Cup of Curling. In playdown play, the rink struggled in the round robin of the 2017 Ontario Scotties Tournament of Hearts, losing two games, and finishing second behind Jacqueline Harrison. However, they won both their playoff matches, including defeating Harrison in the final, qualifying the team to represent Ontario at that year's Scotties. Team Homan defeated Manitoba's Michelle Englot to win the 2017 Scotties, her third Scotties title in four years. She won in an extra end in what many considered to be one of the most exciting Scotties finals ever. Both teams went 10–1 in the round robin, with Homan's lone loss coming at Englot's expense. Englot beat Homan once again in the 1 vs. 2 game, forcing Homan to beat Northern Ontario (Krista McCarville) in the seminal to force the re-match against Englot. At the 2017 world championship in Beijing the Homan rink became only the third 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 ended up going unbeaten right to the end, the only team to do so to date, winning the gold medal by beating Anna Sidorova (for the 3rd consecutive time with wins in the round robin, 1–2 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.
