The 2018–19 network television schedule for the five major English commercial broadcast networks in Canada covers primetime hours from September 2018 through August 2019. The schedule is followed by a list per network of returning series, new series, and series canceled after the 2017-18 television season, for Canadian, American and other series.

CBC Television was first to announce its fall schedule on May 24, 2018,^[1] followed by Global on June 4,^[2] Citytv on June 5,^[3] and CTV and CTV 2 on June 7, 2018.^[4] As in the past, the commercial networks' announcements come shortly after the networks have had a chance to buy Canadian rights to new American series. CTV 2 and Global are not included on Saturday as they normally only schedule encore programming in primetime on Saturdays.
