McCann joined the Grattan rink for the 2017–18 season. It was a good move for him as the team won the 2018 Papa John's Pizza Tankard, McCann's second provincial title. At the 2018 Tim Hortons Brier, they finished 2–5 in the new pool format, failing to qualify for the playoffs. They did manage to win their seeding game however, officially ending with a 3–5 record.[3]
Due to the COVID-19 pandemic in New Brunswick, the 2021 provincial championship was cancelled. As the reigning provincial champions, Team Grattan was invited to represent New Brunswick at the 2021 Tim Hortons Brier, which they accepted.[6] One member of Team Grattan, Paul Dobson, opted not to attend the event due to travel restrictions.[7] He was replaced by Jonathan Beuk of Ontario.[8] At the Brier, the Grattan rink had a strong start, defeating higher seeds Mike McEwen and Brad Jacobs to sit at 4–1 with three games left.[9] They then, however, lost their last three games, just failing to qualify for the championship pool, like in 2020.[10]
