Ricky enjoys marijuana, hash, chicken chips, alcohol, and is Julian's best friend. He's not too bright, partly due to poor education (he just recently received his grade 10), and partly due to drinking and dope smoking. He's frequently shot or injured under embarrassing circumstances. He has a penchant for moral relativism and malapropisms.

In spite of his intellectual and linguistic failings, Ricky is a master horticulturist, having grown and sold large crops of marijuana. He's also an expert at talking his way out of out of trouble with the law, often tricking police and his victims into helping him physically carry the things he plans to steal.

He's fond of knock-knock jokes that don't usually have a punchline so much as a stream of profanity and he frequently wears track pants and a very loud shirt that generally never gets changed for an entire season. He has a severe addiction to smoking cigarettes, causing him to smoke wherever he goes, sometimes even where smoking is prohibited. His diet consists mainly of alcohol, chocolate milk, chicken fingers, chicken chips, pepperoni, cereal and donairs (from King of Donair). He also likes jalapeño potato chips (which he pronounces "ja-LAP-an-o"), all dressed potato chips (which he calls "Dressed All Over") and zesty cheese tortilla chips (which he calls "Zesty Mordant," a send-up of bilingual packaging in Canada, where the French term for 'Zesty' is 'Mordant' and is displayed side by side on the packaging).

His family consists of his father Ray, his girlfriend Lucy, and their daughter Trinity. Ricky was set on marrying Lucy until the wedding was interrupted by the police. Most of the time Ricky lives in an old Chrysler New Yorker, known as the Shit-mobile which is missing its passenger-side front door.

Ricky has also been notorious for kidnapping Canadian musicians Alex Lifeson of Rush (after he refused to sell them tickets to the concert and Ricky insisted on a private concert at the trailer park), and Rita MacNeil (whom he kidnapped, along with her band, forcing them to harvest his marijuana crop at gunpoint).

Julian is the "brains" of the outfit, smarter of the pair and the leader of the group. His main goal in life is to get rich quick (usually from drug related activities and stealing items of value under $1000) and retire. He is never seen without a drink (always rum and Coke, and mouth wash in jail) in his hand, and always wears jeans and a tight, black t-shirt. The sound of ice clinking against glass follows him everywhere. Likewise, he refuses to put down the rum and coke even when he is partaking in heists, having the drink in one hand, and a firearm (his 9mm) in another. Julian has emerged from rollover car crashes with his rum and coke completely intact. Julian is generally more sensible than Ricky, and sometimes thinks of getting a legitimate job, but "Freedom 35", the plan to get enough money through crime to retire early, always lures him back in. He shared a mutual attraction with police officer Erica Miller, but wouldn't give up his career of crime.

Julian was raised by Levi and Desiree after they found him abandoned in the trailer park. Julian does not know who his biological parents are, and has no other blood relatives that he knows about, although he has 'adopted' an elderly woman in the trailer park as his grandmother. She occasionally buys him presents, for which in return Julian baby-sits her dog. This occasionally has disastrous consequences, namely whenever Julian has to deal with Ricky while also taking care of the dog.

Julian and Ricky's best friend and conscience, known for his hoarse voice and coke-bottle glasses. Abandoned as a child, Bubbles lived in a shed for 18 years of his life with his cats, who are his only family. He makes a living by stealing (he calls it remarketing) shopping carts, fixing them, and reselling. The scheme entails the theft of the carts from numerous local malls by tossing them into a ravine, which he later comes back for. He then takes the carts home, fixes them up, and resells them to other malls. He has each of the malls playing off each other, and does not consider what he does a crime. His justification is in that he returns a majority of the profit to those same malls, when he purchases cat food and treats.

An animal lover, Bubbles makes the ballooning population of stray cats his own responsibility, feeding and looking after them.

His name comes from his childhood love of blowing bubbles. His parents abandoned him on Christmas Eve, leaving an explanatory note and an antique bubblemaking machine (a "1967 Electro-bubble"), which Bubbles for a time used to entertain his cats. Sadly, the machine was destroyed when the shed caught fire (the result of a poor wiring job by Ricky, Cory, and Trevor, who were trying to use it as a temporary home for Ricky's grow-op). Bubbles was abandoned by his parents and raised by Julian's foster parents for his own safety due to his parents being hunted down for his father's gambling debts.

Bubbles' evil alter-ego is a ventriloquist dummy named Conky. The pair bear a striking resemblance.

Bubbles loves professional wrestling and even dresses up as his own character, "The Green Bastard." He also drives a go-cart while wearing a Cooper hockey helmet and makes expert use of the word cocksucker.

Bubbles' has been said to be the "Moral center" of the group, in that he represents the purity and innocence that the other characters seem to lack. His perspectives are often rooted in the ideals of staying out of trouble, and helping the meek, illustrated by his love for kitties. In spite of sometimes appearing slightly retarded to some people at first glance, he is really not that dim at all and often he is the very first to really understand what is going on. Surprisingly, whenever the cops swoop into the trailer park to bust one of the boys' operations, Bubbles usually manages to avoid getting arrested or nailed by the police, at least until he was arrested at the end of Season Four by Officer George Green.

A police officer, who was wrongfully dismissed as a result of a prank by Julian, Ricky and Bubbles on Halloween 1977. He's formerly an alcoholic, but has quit drinking as of season 6 and has switched to dope thanks to Ricky. Mr. Lahey ran Sunnyvale Trailer Park at the behest of his ex-wife, the owner of the Park. He is rarely seen without Randy and the two have had a sexual relationship together as revealed to Julian in Season 1 and the rest of the park in Season 3. He develops a drinking problem between seasons 1 and 2 (after Randy leaves him for Lucy), and lets the trailer park decline into chaos. He keeps trying to catch Julian and Ricky at their illegal activities but is fairly ineffective. Has a tendency to use bizarre, rambling extended metaphors involving the word "shit". On the Season 6 finale, he asks Randy to be his character witness at the police board, under the condition that Randy receive tapes of the boys comitting crimes, so Randy can personally bust them. Randy refuses. Lahey instead goes to Bubbles, who agrees under the condition that if Lahey becomes a cop, he won't arrest the boys for anything. Lahey agrees, and with the help of Bubbles, is reinstated as a cop.

Lahey often tries to expose Ricky and Julian's latest schemes by calling in his old police coworkers when he thinks they'll be caught in the act, but this frequently backfires and makes him look even worse in their eyes.

Mr. Lahey's devoted assistant and "longtime companion". In the Christmas Special episode, it is explained that Lahey's wife Barbara found Randy working as a male prostitute in 1997, and, out of her Christian charity, invited him to stay with them for a while. He has an insatiable hunger for cheeseburgers, which has contributed to his large round pot belly and he never wears a shirt, except for once in season 2 (Never Trust a Man With No Shirt On), when he used a shirt to cover a microphone wire in an attempt to catch Ricky and Julian doing something illegal, and once in season 4 (The Green Bastard), when Mr. Lahey was receiving the "Trailer Park Supervisor of the Year" award. Throughout season 6 he is required to wear a shirt if he rides along in police vehicles. Randy was the one who insisted on coming out to the rest of the park after himself and Mr. Lahey are caught in a compromising situation. He went out with Lucy for a short while during Ricky's stay in prison between seasons 1 and 2.

Randy was once a male prostitute who went by the handle "Smokey". He will sometimes fall back on this job whenever he doesn't have any money for cheeseburgers. Smokey can be found in front of the King of Donair, or Dairy Queen, where he prostitutes himself for either cheeseburgers, or dairy queen coupons.

It is revealed during season 6, that Randy is in fact a bisexual, when he states he is attracted be both men and women.

Ricky's on-again, off-again girlfriend and mother to his child, Trinity. Lucy and Julian had a relationship in Junior High, and Lucy still expresses feelings for Julian from time to time. Gets a boob job in Season 5, which Ricky does not notice at first.

Lucy's best friend. She moved in with Lucy and Trinity while Ricky was in prison at the beginning of season 1. She dated Ricky for a while and encouraged him to focus on school. However this didn't last long. As soon as Ricky got rich, she was instrumental in getting Lucy to file a child support suit against Ricky. In seasons 4 and 5, she dated both Cory & Trevor (as one entity) and they asked her to marry both of them. She is the co-owner of a hair salon in the park.

In the first season, Sara was mainly used for commentary and to inform the audience about the other characters on the show, although starting in Season 2 she began to play a larger role by dating Ricky. Sarah is also the real life daughter of John Dunsworth (Mr. Lahey)

A rapper who lives with his mother at the trailer park. Often mistaken as an Eminem wanna-be. He speaks in ebonics and very frequently asks "gnome sane'?" (Know what I'm saying?) He often helps Ricky and Julian out. He also occasionally makes forays into the amateur international porn market (his titles to date are the low-budget movies, "From Russia With the Love Bone", "The Bare Pimp Project" and "J-Roc's Greasy Trailer Park Girls Gone Wild"). His real name is Jamie.

In the episode Who's the Microphone Assassin? viewers are reminded that J-Roc, and even people around him, forget that he's white. In the same episode, J-Roc was caught masturbating. In Dear Santa Claus. Go Fuck Yourself, which takes place in 1997, J-Roc speaks very plainly and professes that he had never smoked marijuana up to that point in time.

Has come up with all sorts of nicknames for Randy. Including: Rico Suave looking mafucker, Roch Voisine with a gut, Inflatable Elvis, Gut Cassidy and the Sundance Cheeseburger, and Starsky and Gut (Lahey & Randy). He is also the soon to be father of two children and has decided to soon step out of the rap game as of the newest season.

Trevor and Cory are two rather stupid young adults who are often used as lackeys by Ricky and Julian, but it's rarely worth the effort because they have a tendency to screw up everything. Invariably, the pair are used by Ricky as scapegoats whenever something illegal doesn't go according to plan. Julian manages them with dog training techniques. Trevor is constantly being harassed for cigarettes by Ricky, who snaps his fingers and says "Smokes - Let's go!". Everyone treats them as effectively one person - one entity. Cory and Trevor share several traits with Rosencrantz and Guildenstern of William Shakespeare's Hamlet, given the pair's few distinguishing characteristics as well as their roles as (rarely successful) lapdogs of Ricky and Julian.

Ray is Ricky's father who enjoys drinking alcohol, listening to blues music and reading the Bible. Ray is a deeply devout Calvinist, and is also addicted to video lottery terminals. He constantly steals his son's pepperoni. For the purposes of claiming disability benefit, he spends most of his time in a wheelchair although he is not disabled and will stand and walk around normally when he believes no-one is watching. Interestingly enough, his wheelchair has three flags on it, a Jolly Roger flag, a Canadian Flag and a Confederate flag. Ray was sent to jail for disability fraud after Lahey and Randy called the police. Ray used to be a truck driver. After being evicted by Barb and Randy, Ray was forced to live at the nearby garbage dump inside of his truck's old cab. At the time of his eviction he was stealing cable from the other trailers and firing high velocity piss juggs from his old cab into nearby trees and onto the roofs of houses. Currently, thanks to Bubbles and Lahey, Ray has been instated as the Assistant Trailer Park Supervisor.

Sam is a former veterinarian who lost his job after helping Ricky fix a bullet wound. He later ran for Trailer Park Supervisor but lost to Jim Lahey after Julian slipped hallucinogenic mushrooms into his food prior to his speech to the residents of the park. Then he got his veterinary license back (on probation) and started up his practice again. He has a mild demeanor, but is not particularly fond of Ricky or Julian. His favourite food seems to be greasy hot dogs and has been called a "caveman" by Ricky, Julian, and most recently Randy. In season 6, Sam had a new job at a paving company, but after a prank call by Ricky, loses the job. He places the blame on Randy, who he believes had made the call, and temporarily took Randy hostage in an attempt to trade him for money to pay off the fines he had received.

Tyrone is J-Roc's sidekick and together the duo have been involved in many gangster like activities. The latest scheme was that he was part of a parcel-pickup theft scam in the trailer park. His real name is Tyler, but prefers to be called "T". In Dear Santa Claus. Go Fuck Yourself, which takes place in 1997, Tyrone speaks very plainly and professes that he had never smoked marijuana up to that point in time.

Tyrone and DVS are J-Roc's managers. Tyrone is part of the original cast, while DVS was introduced in the episode Who's the Microphone Assassin?. In that episode, DVS found out from Mr. Lahey about how J-Roc was pirating his songs, and proceeded to crash his rap concert at the trailer park and threatened him. He later had a change of heart when the park residents told him about J-Roc, and since then DVS and Tyrone together manage J-Roc's career. It was Tyrone and DVS who came up with the idea of having J-Roc pretend to go to jail to increase his street cred. Ricky often calls DVS "DVD". Does not hail from Detroit, as his name would imply, but rather from Moncton, New Brunswick.

The local police officer most often dispatched to deal with Ricky and Julian. He is easily fooled by the pair and it is very rare that he makes an arrest. In season 6, he was caught in Lucy's trailer by Ricky, handcuffed to her shower almost naked, apparently during sex.

Bully who enjoys waving his gun around and terrorizing the residents of the trailer park. Ruled over the park while Julian and Ricky were in jail at the start of Season One, becoming their nemesis, and has showed up several times since. He is still trying to get his Grade 10.

"Trin" has an addiction to cigarettes and sometimes gets drunk, which usually ends up with Lucy being angry at Ricky. She has eaten hash brownies made by Ricky (unbeknownst to him) in the episode "Mrs. Peterson's Dog Gets Fucked Up", with her exclaiming, "These brownies taste funny.". She has occassionally been cast as a particpant with the Bottle Kids. Played by Jeanna Harrison.

Terry and Dennis are a pair of Japanese-Canadian brothers who use their grandmother's house as a cover to deal hash. The brothers debuted in the episode Give Peace a Chance in season five. Ricky knows them well since their childhood days, but they are not well-liked by Julian and Bubbles. The brothers like to walk around the house wearing only their bathrobes while not covering their private parts. Bubbles labels them with many identities like "the flappy bird brothers"

The detective officer who arrested Ricky at his wedding (season one). He returns in season five as George Green's replacement, and in season six as an officer along with George Green. There is no indication as to why he went down in rank from detective to ordinary officer. He has recently been romantically linked to Randy after running up a large tab on cheeseburgers.

The character who occasionally screams loudly but who is always off-camera. He typically yells "What in the fuck?!"
