''Life With Derek'' was a [[CanadianSeries Canadian]] [[LiveActionTV live-action]] [[DomCom domestic comedy]], produced for Canada's Family Channel, which gained a respectable [[{{Eagleland}} American]] audience airing on DisneyChannel. The show focused upon [[TheBradyBunch two families merging together after divorces]]. By your average NuclearFamily standards, the siblings don't get along all the time and HilarityEnsues. The main character is Casey, a perfectionistic teenage girl who has a rivalry with the titular Derek. The show ran for two short thirteen-episode seasons (2005-06 and 2006-07) and two full seasons (2007-08 and 2008-09).

TheMovie, ''Vacation with Derek'', premiered in Canada on June 25, 2010, [[NoExportForYou but failed to make its US premiere date of December 10, 2010]]. The film, however, finally made its U.S. debut on Saturday, May 14th, 2011.... on Starz Kids. At 1:50 PM in the afternoon.

In late 2012 there was scheduled to be an official relaunch with the working title "Life With Derek, Again" involving the original cast members in pre-production. [[WhatCouldHaveBeen It was not picked up for production.]]

!Tropes used by ''Life With Derek''
* AdultFear: In TheMovie, Marti goes missing and when Derek and Casey go to find her, they find her canoe overturned in the water and Derek visibly panics.
* AllGuysWantCheerleaders: Casey joined the pep squad because she assumed this was expected of her as the football hero's girlfriend.
* AloofBigBrother: Derek oscillates between being this and a BigBrotherMentor (who just happens to really suck at it) depending on his mood.
* AlphaBitch: Max's cheer-captain ex-girlfriend Amy.
* AmateurSleuth: Edwin and Lizzie try their hands at it, and fail miserably (Edwin more than Lizzie.)
* AnimatedCreditsOpening: The opening sequence for TheMovie is StopMotion animated.
* AnnoyingYoungerSibling: Edwin takes the cake, though Marti and Lizzie have their moments.
* ArcWords: The phrase "Blended Family" grates on the nerves after four seasons.
* AscendedExtra: Sheldon Schlepper, who was originally supposed to only be in one episode.
* BeCarefulWhatYouWishFor: Casey learns this the hard way on her sixteenth birthday when she wishes Derek out of her life. [[spoiler: But considering that it's all a dream, and the audience is well aware of it...]].
* BeautyBrainsAndBrawn: Male versions, with Derek getting the looks, Sam the brains and Ralph the brawn.
* BelligerentSexualTension: Speculation abounds regarding this between Derek and Casey. Thick enough between Truman and Casey to serve up with an ice cream scoop.
* BigManOnCampus: Max. Derek tries.
* BlackBestFriend: Emily.
* BlahBlahBlah: When Sam is talking to Derek about his and Casey's recent argument, this is all Derek hears.
* BlondeBrunetteRedhead: Male versions of it found in Sam, Ralph and Derek, all three being best friends and jocks, with Derek being the only JerkJock out of the three. Also, BeautyBrainsAndBrawn, with Derek getting the looks part, Sam the brains and Ralph the brawn.
* BookDumb: Derek obviously isn't stupid. He just has other priorities.
* BrainyBrunette: Casey and Lizzie both qualify.
* BreakingTheFourthWall: Casey addresses the audience [[OnceAnEpisode each episode]] immediately following the TitleSequence.
* BrilliantButLazy: George managed to become a successful attorney despite having been a slacker and a ne'er-do-well in high school. Derek arguably qualifies, as well.
* ButtMonkey: Edwin
* CanadaEh: Generally averted, but not altogether avoidable in a self-consciously Canadian show. At one time, averted and mocked in one episode.
** And the accents. ''Dear Lord'', the accents.
* CallingTheOldManOut:
** The three younger siblings raise some serious Cain when they're expected pick up the slack around the house when Casey and Derek have to study for finals, without any additional consideration or compensation.
** In TheMovie, Casey stands up to her grandmother Felicia in defense of George and the rest of the Venturi clan.
* TheCastShowoff:
** Ashley Leggat, who plays Casey, is a professionally-trained dancer, and the show emphasized this repeatedly in later seasons. The TV-movie ''Vacation with Derek'' even made a whole subplot out of this, casting ''[[SoYouThinkYouCanDance So You Think You Can Dance Canada]]'' winner Nico Archambault as her love interest.
** Leggat is a triple threat entertainer. She is also a singer, having sung a few times on the show.
* CatchPhrase: Casey's annoyed reaction of "''Der''-ek!" The distinctiveness is in how she says it. [[LampshadeHanging Lampshaded]] in the episode "Open Mic Plight" when Derek responded:
-->'''Derek''': ''Ca''-sey! ''Sal''-ly!
* CharacterDevelopment: By the end of the series, Casey is much less of an obsessive-compulsive ControlFreak and has learned to relax and enjoy life, and Derek has gotten over his fear of commitment and does right by his family more often than not. That's not to say there aren't still times when they're positively insufferable.
* {{Cloudcuckoolander}}: Ralph
* CompanionCube: Marti has her stuffed monkey, Sir Monksalot.
* ChuckCunninghamSyndrome: Noel. His last appearance in an early season four episode had him coming to terms with him being just friends with Casey. It was an obvious set up for a PlatonicLifePartners friendship or possibly another LoveInterest for Casey. But then Truman came in, and Noel never showed up again.
* DarkHorseVictory: Emily was the first write-in candidate ever to be elected Student Body President of Thompson High.
* DefrostingIceQueen: Grandma Felicia in TheMovie.
* {{Dojikko}}: Casey started out as this, garnering the nickname "Klutzilla." This was eventually [[SeriesContinuityError forgotten]] and Casey became an accomplished dancer.
** There were episodes where she was stated [[InformedAbility to have been dancing since she was little]]. The clumsiness was a more one episode thing because it only happened when around her crush at the time, Sam.
* DomCom
* DrivesLikeCrazy: George is a notoriously-reckless driver, even losing his license on the eve of Derek getting his. [[InformedFlaw Or so we're told. We never actually see him drive]].
* DrivingADesk: Derek's driving test.
* DrugsAreBad: Casey attempted to intervene when she thought Derek was selling drugs (and using Edwin as his bag-man.) [[spoiler:It turns out he was just selling office supplies his dad stole from work, and [=CDs=]]].
* EaglelandOsmosis: This show provides a fascinating look at the similarities and differences between Canadian and American culture. The show itself could be considered a case of ''reverse'' osmosis, due to its popularity in the States.
* ElectionDayEpisode: There was an episode where Casey uses her stepbrother Derek as a puppet to run for school office and get the "cool" vote while enacting her ideas. [[spoiler: Their friend ends up winning as a write-in instead]].
* ExpositoryThemeTune
* {{Fanservice}}:
** Three words to describe Casey in her ''Babe Raider'' outfit: [[HappyDays Yeowza, yeowza, yeowza!]]
** In one episode, Casey is seen reviling over the disorganization of the bathroom, clad in only a towel. About as hot as you'll ever see on DisneyChannel.
* FirstNameBasis: The Venturi kids with Nora, and the [=McDonald=] girls with George.
* FirstNameUltimatum: ''Der''-ek!!
* FlirtyStepsiblings: Unintentional on the writer's part, intentional on the actors'.
* FoolishSiblingResponsibleSibling: The Venturi brothers and the [=McDonald=] sisters.
* FourTemperamentEnsemble:
** Casey (melancholic), Derek (choleric), Edwin (phlegmatic), Lizzie (leukine), and Marti (sanguine).
** The parents: Nora (melancholic) and George (sanguine).
* GenerationXerox: Derek is doing his best to live up to his father's high school reputation (evidenced by a file that requires its own box) as an underachieving prankster.
* GraduateFromTheStory: The series finale "Futuritis" features Casey and Derek's high school graduation.
* HandsomeDevil: Derek. Oh, dear God, Derek.
* HandsomeLech: Derek strikes out about as often as he scores.
* HappilyMarried: George and Nora both seem to have gotten it right on the second try.
* HeelFaceTurn: [[spoiler: Roxie in TheMovie]].
* HighSchool
* HighSchoolDance: Uses the 'boy has to ask a girl' theme to a tiring extent, resulting in a long-winded "[[HilarityEnsues hilarious misunderstanding]]" about who asked whom.
* HilariousOuttakes: [[EveryEpisodeEnding Over the end credits of every episode]].
* HollywoodNerd: ''Casey. Oh, my Lord, yes, Casey''.
* HypocriticalHeartwarming: Let it be known that Derek is the '''''only one''''' allowed to insult Casey.
* IDidntMeanToTurnYouOn: Casey has a nasty habit of giving guys the wrong impression. Noel and Ralph come to mind most readily.
* IdiosyncraticWipes: The pantomime skits between scenes.
* ImaginaryFriend: Marti's imaginary friend Daphne, [[{{Tuckerization}} named for series creator Daphne Ballon]].
* JerkJock: Played straight with Derek, and subverted with his [[LovableJock modest, likeable hockey buddies]] Sam and Ralph.
* JerkWithAHeartOfGold:
** Derek when he's not [[{{Jerkass}} just a jerk]]. Especially with [[MoralityPet Marti]] and Casey, [[http://www.youtube.com/watch?v=eX38T7JnC6c especially when she cried]].
* JustFriends: This trope is the actual title of an episode which is devoted entirely to playing straight, subverting, deconstructing, and generally having fun with the trope.
* {{Kidanova}}: Derek walks the line between being this and a straight [[TheCasanova Casanova]].
* TheKlutz: Casey, who is given the nickname "Klutzilla" very only on. However, in later seasons, she is also shown to be a talented dancer ([[TheCastShowoff much like the actress who plays her]]), so it's hard to buy her pratfalling as genuine.
* LastMinuteHookup: In the penultimate episode, between [[spoiler: Derek and Emily]].
* LaughTrack: This show is notable, along with ''NaturallySadie'' and ''PhilOfTheFuture'', in that it doesn't have one, although goofy sound effects and guitar riffs are used to much the same effect.
* LethalChef:
-->'''Edwin''': Didn't Derek tell you to show up ''after'' dinner?
-->'''Lizzie''': Yeah, friends don't let friends eat here.
-->'''Nora''': Hey!
* LoadsAndLoadsOfCharacters: Seems to be a Canadian thing.
* LockedInARoom: Derek and Casey get locked in the bathroom in "The Party" and bonding ensues. Although... whether or not Derek was being sincere is up for debate...
* LondonEnglandSyndrome: An interesting aversion, in that we eventually learn the show is set in London, Ontario (population 350,000, about halfway between UsefulNotes/{{Toronto}} and UsefulNotes/{{Detroit}}), but they never come out and call it "London, Ontario".
* LovableJock: Sam and Ralph.
* TheMasochismTango: Sam and Casey's extremely fragile on-again, off-again relationship.
* NotBloodSiblings: Often an excuse of the shippers.
* NuclearFamily

** Casey and:
*** [[TheMasochismTango Sam]]
*** [[AllGuysWantCheerleaders Max]]
*** [[BelligerentSexualTension Truman]]
** Derek and:
*** Kendra
*** Sally
*** [[spoiler: Emily]]
* OnlySaneMan: Nora
* ParodyNames: An episode called "[[Franchise/TombRaider Babe Raider]]" focused on the controversy surrounding the titular video game.
* PetTheDog: Every episode.
* PlatonicLifePartners: In contrast to their elder siblings, Lizzie and Edwin have one of the best-written platonic relationships on television. Still doesn't stop the shippers, though, as the fans have made them into a {{Fanon}} NotBloodSiblings BetaCouple.
* PortmanteauCoupleName:
** [[FanPreferredCouple Dasey]] is popular with shippers.
** To name a few others: [[OfficialCouple Geora]], [[PlayingHardToGet Dally]], [[VictoriousChildhoodFriend Demily]], [[LetsJustBeFriends Sasey]], [[WhyWouldAnyoneTakeHimBack Trashy]]...
* PrecociousCrush: Lizzie develops one on her soccer coach in one episode. [[spoiler: Too bad he turned out to be a player.]]
* PutOnABus: Sheldon, and later, Sally.
* ReasonableAuthorityFigure: Principal Lasseter is a disciplinarian, but is also willing to consider more important things, such as the effect of expelling Derek on school morale.
* RecycledInSpace: ''Series/EvenStevens'' AS {{THE BRADY BUNCH}}! IN CANADA!
* RunningGag: '' 'DER-ek-!' '' The more emphasis on the first syllable, the angrier Casey is when she says it. Inverted in 'Futuritis', when she says it (as Derek appears on stage) in a very soft, loving fashion.
* SayMyName: '''''[+DER-EK!!!+]''''' Casey isn't the only one who says it like that, either. In one episode, they [[LampshadeHanging lampshade]] it by having the characters ''bet'' as to whether Derek can get everyone to say his name like that. [[spoiler:And yes, he wins.]] It's also become a very popular and simple drinking game, much like [[TheBobNewhartShow "Hi, Bob!"]]. The rules? Drink whenever anyone says "Derek".
* SensitiveGuyAndManlyMan: Edwin and Derek.
* SheIsAllGrownUp: Slightly subverted in that Casey is already a teenager, but oh, her moving through puberty is oh, so noticeable...
* ShoutOut:
** George's old high school band was called "[[GeorgeOfTheJungle George in the Jungle]]."
** Derek pronounces "moron" as "[[BugsBunny maroon]]."
* SlapSlapKiss: How Casey and Truman came to be.
** [[FanPreferredCouple 90% of the fandom also expected Casey and Derek to end up together because of this.]]
* SoapboxSadie: Lizzie takes treehugging to a whole new level.
* SoapOperaRapidAgingSyndrome: Edwin's age jumped from 10 to 12 when Daniel Madger's voice dropped.
* SpellMyNameWithAnS: Casey's first clue that Derek had put his name on her math test (and vice-versa) was that he'd spelled her last name "Mac" rather than "Mc." His response:
-->'''Derek''': Are you sure? Because "Mac" just feels right.
* StandardizedSitcomHousing: Delightfully averted. The [=McDonald=]-Venturi home is an older-style three story dwelling, of which multiple rooms are seen from multiple angles.
* StrawFeminist: Casey seems to think the word "Secretary" is sexist, and insists that her stepfather use the more politically-correct "Administrative Assistant."
** StrawmanHasAPoint: Casey had a lot of good points in "Babe Raider".
* SweaterGirl: Casey, and [[LampshadeHanging lampshaded in the opening sequence.]]
* TallDarkAndSnarky:
** Derek
** Also minor character Noel in his first appearance.
* TeamMom: Casey
* TheyCallMeMisterTibbs: Principal Lasseter gets rather indignant at George's attempt to address him [[FirstNameBasis by his given name]].
* ThisIsMySide: When Derek and Casey were staying at the house alone while the rest of the family went on a road trip, Casey taped parts of the house pink (her side) and blue (Derek's side) so that they would avoid running into each other.
* ThoseTwoGuys: Sam and Ralph, depending on the episode.
* ThreeWallSet: Averted in this series through the use of a more cinematic Single Camera format (quite rare for a sitcom.)
* TitleThemeTune
* TomboyAndGirlyGirl: Lizzie and Casey.
* TriangRelations
* TwoLinesNoWaiting
* TwoTeacherSchool: Averted. Rarely is the same teacher seen twice.
* UnsympatheticComedyProtagonist: Derek mostly, although Casey ventures into this territory quite a lot.
* UptightLovesWild: Unintentional, but if it wasn't...
* {{UST}}: Unintentional between Casey and Derek, middling to so-so between Derek and Sally before they became a couple, and burning hot between Casey and Truman before they hooked up.
* VictoriousChildhoodFriend: Patience really paid off for [[spoiler: Emily and Derek]].
* ViolentGlaswegian: Casey and Truman's fencing coach Fergus is a toned-down version.
* VisitByDivorcedDad: Casey and Lizzie's dad and the Venturi kids' mom both make appearances. They're as active as is practical in their kids' lives.
* VitriolicBestBuds: Derek and Casey's relationship could be seen like this.
* WackyMarriageProposal: Two of them:
** In a FlashBack episode, Casey and Derek have such a lousy rapport that they try, and initially succeed, at torpedoing their parents' marriage plans. [[spoiler:[[CrowningMomentOfHeartwarming In the end, Casey proposes on behalf of her mother, and Derek accepts on behalf of his father]]]].
** At their junior prom, Sheldon proposes to Emily in front of the entire student body. [[spoiler: He's about to [[PutOnABus move to Newfoundland with his parents]], and is making a last ditch effort to hold onto Emily]].
* WhyDidItHaveToBeSnakes: Literally snakes, in this case. Derek's phobic of them.
** He's also afraid of mice.
