Andre Richard pleaded guilty to arson and two counts of aggravated assault and was sentenced on Tuesday.
Provincial court Judge Peder Gulbransen said the sentence had to reflect the severity of Richard's crimes and his history of domestic abuse.
Richard was originally charged after the home where his estranged wife and her two children were sleeping went up in flames last year.
All three managed to escape, but prosecutor Mike Fortino said the impact on the family has been tremendous and ongoing.
With credit for time served, Richard will be in prison for about 8 1/2 years. (CKNW, News 1130)
