In 2018, the first season with new captain Frank Dancevic, Canada lost once again in the first round of the World Group by the score of 1–3 to Croatia. Borna Ćorić won the first rubber over Pospisil, and Shapovalov won the second over Viktor Galović. Despite leading 6–2, 6–3, 4–2, Nestor and Pospisil lost the crucial doubles match against Marin Čilić and Ivan Dodig in five sets. The final day, Shapovalov lost to Ćorić, meaning that Canada had to play a playoff tie in September versus Netherlands to secure its place in the World Group for 2019, which they won by a score of 3-1, through two singles wins by Raonic and one singles win by Shapovalov.
