Life With Derek Logo

Life with Derek is a Canadian sitcom that aired on Family Channel (English) and VRAK.TV (French) in Canada. It aired on different networks internationally, such as Nickelodeon in Australia and Asia, Boomerang in the United Kingdom, and Disney Channel in Asia, Central America, France, Germany, Israel, Italy, Mexico, Portugal, South America, Spain, and the United States. It premiered on September 25, 2005 and ended on March 25, 2009 spanning 4 seasons, 70 episodes. The show is about a lawyer named George with three kids named Derek, Edwin and Marti. George then marries a divorced woman named Nora who has two children named Casey and Lizzie.

Up until that point, Casey McDonald was perfectly content with her life. Growing up as the oldest child in a household in Toronto with only her mother and sister had suited her well and brought her up as a self-sufficient and independent young woman.

With the addition of a stepfather, two stepbrothers, a stepsister, new school, new house and overall a whole new life, Casey struggles to find her place within the new family. The series is also based on Casey and Derek's rivalry.

The family is revealed to live in London, Ontario, Canada, when George is reading a newspaper titled London Chronicle in episode "Don't Take a Tip From Me." Also, in another episode, "All Systems No Go," he refers to himself as "George from London," and in "Dinner Guest," when Lizzie explains how her dad's been to London and Paris, George remarks, "I've been to London and Paris...Ontario."

Season 1 episodes of Life with Derek were filmed in Corner Brook, Newfoundland and Labrador, Canada.[1]

The Rivalry

Prior to becoming members of a blended family, Casey and Derek were firmly comfortable in their roles as first-born children, including having a major influence on how family decisions were made. When their families blend, each strives for dominance: Casey by "sticking to the rules" and Derek by asserting himself with both force and manipulation. This is further complicated because Derek and Casey are in the same grade in high school; the situation is harder for Casey, who's trying to make new friends and fit in at her new school, where things are much different than her previous all-girls school. Both teens aren't afraid to speak their minds, especially when trying to recruit their respective parents and/or brothers and sisters to be on their side.

The sibling rivalry grows intense at times, and it causes them to constantly try to one up the other in order to get their way. It often involves getting really sneaky and having to risk being grounded by the adults. They are persistent, no matter who gets in the way, whether it's friends or family. In their struggle to find their place, both at home and at school, Casey learns to "loosen up" and break a rule or two, while Derek learns to occasionally "walk the straight and narrow" and put family interests ahead of his own gain, even if it means that Casey benefits. Sometimes, this resolution comes only after Lizzie and Edwin negotiate as (sometimes unauthorized) agents for their respective biological siblings to overcome some impasse or communications breakdown between Casey and Derek.

The show includes several cut-scenes, where various members of the family (usually the ones involved in a problem) interact with one another in a way that is symbolic of their current issue, performed in a nondescript setting with no background.

Despite Casey and Derek's constant bickering and disagreements, they have been known to come together to cooperate toward a common goal, or to use one another to further their own selfish agendas. Although the rivalry continues, they sometimes try to help each other in the series. This not only benefits their relationship, but their parent's relationship, as well. It also shows that even though they argue and fight, they grow to accept each other.
