Spencer Jordan, Meika's father, and Marie Magoon, her stepmother, were originally charged with first-degree murder.
But after a nearly five-week trial, the judge found them both guilty of the lesser charge earlier this month.
Meika Jordan's mother collapses with grief after murder trial testimony
During the trial, court heard that Meika was burned, beaten, punched, dragged by her hair and thrown down the stairs over a three-day period leading up to her death in November 2011.
Court heard evidence from an undercover police operation, when both Magoon and Jordan confessed to abusing the child.
Meika died on Nov. 14, 2011, after being taken to hospital by ambulance the day before.
Magoon and Jordan originally told paramedics, police and doctors she'd fallen down the stairs.
A sentencing hearing has been scheduled for September. If the Crown's move for an appeal is granted, it would be scheduled for after the sentencing.
A second-degree murder conviction comes with an automatic life sentence with no chance of parole for 10 to 25 years. A first-degree murder conviction is also a life sentence, but with no chance of parole for at least 25 years.
Crown lawyer Susan Pepper has already indicated she will seek the upper end of the maximum sentence for the pair.
