- The Ace: If something competitive is brought up, Brent will Excel at it.
- Actor-Shared Background: Both Brent Butt and Brent Leroy were lead guitarists in their high school Garage Band. In a bit of Celebrity Paradox, Brent Butt's band, Fast Exit, managed to become world-famous within the Corner Gas universe and is Brent Leroy's favourite band of all time.
- Big Eater: The undisputed king. He ate an entire bowl of perogies in under 5 seconds, and said it wasn't his best time.
- Cloud Cuckoolander: Not as bad as Hank, but he has signs of this.
- The Danza: Played by Brent Butt.
- Deadpan Snarker
- Geek: Is a big fan of comic books, and he'll occasionally drop references to Marvel Comics. Notably, he'll even mention obscure titles or characters, like Sasquatch from Alpha Flight.
- Hidden Depths: His interest and skill at stand up comedy
- Kavorka Man: Although he doesn't actually get any girls... because they all think he is way out of their league. Lacey theorizes that it's because the relatively normal Brent is basically an Adonis when compared to the average Dog River man, so the Dog River women have adapted and lowered their standards. The other women all think she doesn't know what she's talking about.
- Lazy Bum: In addition to Gluttony, Brent's other deadly sin is Sloth (in fact, these two aspects of his personality once had an argument in his mind, and Sloth won). Brent is so lazy that he was unaware that men can pee standing up (apparently never bothering to try it himself when sitting was an option), and then there's this conversation:Lacey: How's it goin'?
Brent: I'm sittin' down. I'm eating. For a lazy glutton, this is like a perfect day.
Lacey: What is it you love so much about chili cheese dogs?
Brent: Are you kiddin'? What don't I love about them?! ... Actually, I don't love the poppy seeds on the bun. Could you get some plain ones?
Lacey: No, just brush 'em off with your hand.
Brent: ...You heard me say I'm lazy, right?
- Must Have Caffeine.
- Only Sane Man: Sometimes
- Super Senses: Since he's such a Big Eater, his sense of taste is superb. After eating the above-mentioned perogies in under 5 seconds, he complimented Davis for using a hint of tarragon in the butter. When eating a chili cheese dog at normal speed, he is able to correctly identify the brand name of the wiener.
- Trademark Favorite Food: Chili cheese dogs.
- Catchphrase: "Jackass", "Holy Hell!", "My taxes pay your salary!"
- Follow in My Footsteps: In the series finale, it's revealed that he burned Brent's letter of acceptance into college so that he'd be around to take over the gas station.
- Grumpy Old Man
- Iconic Outfit: His green hat. This fact is not lost on the characters. Also, when he starts counterfeiting Dog River Dollars, he buys several green hats for himself, as well as a blue hat. "That was an impulse buy!"
- Intergenerational Friendship: With Davis.
- Lethal Chef: Emma claims that the last time Oscar tried to cook something, he broke the toaster, and he wasn't even making toast. Then there was the time he made a salad and it spontaneously exploded in his face.
- Never Bareheaded: He is never seen without his green hat, although Emma makes him take it off at the table.
- Pet the Dog: In the animated series, it is revealed that he's nice to Emma during a blue moon as her father died during one.
- Screw Politeness, I'm a Senior!
- There Should Be a Law: Frequently demands that Davis and Karen arrest people for causing any minor inconvenience to him. So frequently that when they went all morning without getting any complaints from him, they assumed he must have died.
- Cool Old Lady: At times
- Fantasy-Forbidding Mother: In the series finale, she disapproves of Brent preforming stand-up comedy because she thinks a middle-aged man should settle down and "be stuck in a rut with a wife and kids, living the Hell we all lived". Oscar calls her out on this, though as noted in the Follow in My Footsteps example above, he's no better.
- The Friend Nobody Likes: In her knitting group. She drives them crazy because whenever they get together, she never shuts up complaining about Oscar. The group would rather hang out with Hank than her.
- I Want Grandkids: Wants Brent to settle down because of this. To her chagrin, he and Lacey decide not to have them when they do settle down together
- Never Mess with Granny: By far the most physically strong character, but still has all of the standard old lady hobbies like knitting and gardening. The gardening is likely what made her so strong in the first place, lugging around heavy bags of soil and fertilizer.
- Shipper on Deck: For Brent and Lacey, mostly in The Movie, but did say she hoped he was interested in her during the series
- Sore Loser: Always. For example, when she loses the annual jam contest to Fitzy's grandma after fifteen consecutive wins, she goes into such a funk that she accidentally smashes every plate she and Oscar own, tears up her berry garden and paints "BAD JAM" on the fence, and trashes the women's bathroom at Corner Gas/The Ruby while writing "JAM SUCKS" on the mirror in lipstick. The only thing that snaps her out of it is learning that the winner of the contest had stolen one of her recipes and used it.
- Stop Having Fun Guy: When playing Bridge. Although when Wanda acts like a Stop Having Fun Guy towards her, she tells Wanda to shut up and stop being a know-it-all. Her commitment to winning at any cost is also shown in the episode where she plays Bingo. She does everything in her power to get the old Bingo caller to return to his job despite the fact that he is badly injured and the fact that Wanda is much better at the job, because he admitted to having a crush on her and deliberately calling her numbers so that she would win every time.
- Stout Strength
- Supreme Chef
- Women Are Wiser
- Abhorrent Admirer: is implied multiple times to have a crush on Lacey, which she doesn't like
- Cloud Cuckoolander
- The Ditz
- Dumbass Has a Point
- The Friend Nobody Likes
- Genius Ditz: Surprisingly adept as a handyman. Of course, while he's quite good at doing the work, good luck getting him to actually do the work. He also has an incredible knack for choosing the perfect gift for the occasion, no matter how bizarre the gift seems. For instance, he has Oscar get Emma a bathroom scale for an anniversary gift. She loved it, interpreting it as Oscar caring about her health.
- Kavorka Man: Is very passionate about fishing and talks about it using such poetic language that Even the Guys Want Him. Or at least Davis does.
- Middle Name Basis: Goes by the short form of his middle name Henry.
- Sore Loser: At least when it comes to golf.
- The Alleged Car: His truck
- Brilliant, but Lazy: To the point that sometime after the series finale she went back to college in order to complete her PhD in theoretical physics... then used it as leverage in negotiating a small salary raise from Brent.
- Deadpan Snarker: The snarker of the show, and that's saying something.
- Ditzy Genius: Somewhat. Wanda holds a Masters in Theoretical Physics, yet fails in many social situations and can't do simple math.
- Green-Eyed Monster: If someone upstages her at anything, from playing piano to putting together Brand X IKEA furniture, she becomes furious and starts trying to sabotage or discredit them. Davis is better at piano than her, so she manipulates him into quitting his lessons so that she can become Emma's only student. Karen puts together the furniture faster than it took her to do Step 1 of the instructions, so she declares Karen must have done it wrong and takes it apart again as soon as she leaves the room, purposely breaking a piece off to use as "proof" that Karen did not put it together correctly.
- Sesquipedalian Loquaciousness
- Weaksauce Weakness: Can't do simple math.
- She's also quite ticklish. Her agoraphobia could also count, considering she lives in Saskatchewan
- Bad Liar
- Blithe Spirit, Fish out of Water, Naïve Newcomer: which often results in...
- Cannot Tell a Joke: Her attempts at humor often lead to her being the only one laughing.
- Can't Take Criticism: Take any of the negative tropes listed about Lacey here, and she has denied it at one point or another.
- Deadpan Snarker
- The Determinator: Any time she needs to prove she's right about something, such as proving Wanda ripped her off on jewelry, demanding that Hank stain her deck, being adamant about her bulletin board rules, proving that home-baked cookies are better than packaged ones, etc.
- Hidden Depths: Surprisingly adept at coaching hockey, and at competitive eating (although she's still nowhere close to being on Brent's skill level).
- Kindness Button: Lacey can switch from angry to pleasant in an instant if provided the right trigger. For instance, she goes from displeased at Brent for encouraging Hank to make up an unflattering story about her, to immediately happy and proud when Brent compliments her storytelling skills.
- Ms. Fanservice: Played with. Lacy is younger and cute, wears a lot of tank and halter tops and has no issue showing a bit of cleavage, but it never reaches vampy or Stripperiffic levels. If anything, she looks like the average woman her age. This is lampshaded in "Doc Small" when a doctor from an even smaller town than Dog River is asked to consider becoming the town physician. Assuming the doctor is a man, Lacey wears a "flirty" top that even less revealing than her normal garb, but the female doctor has never seen anything like it before, asking if the town is large enough to have a Red Light district, and tells Lacey that she dresses "slutty".
- Sore Loser: She doesn't take losing very well. If she has someone else to blame for it, she gets mad. If she has nobody to blame but herself, she becomes depressed and self-loathing, developing an "I can't do anything right so what's the point in trying?" mentality that causes the quality of the food at the Ruby to suffer greatly (she brings Karen a plate of fish sticks that are still frozen, for example).
- Unsportsmanlike Gloating: She's a very competitive person and when she wins she revels in it. The only exception was when she won an Eating Contest, which she felt pretty ashamed of.
- Verbal Tic: When proving a point, Lacey often starts her sentences with a terse "Look it!".
- Camp Straight: Spent the entire year's police budget planning/decorating a wedding and reads Cosmo every month, but is stated to be divorced and has expressed his attraction to Big Beautiful Women. Then again, there was that time he went fishing with Hank.
- Clueless Boss: To Karen
- The Ditz: Shared with Hank.
- Intergenerational Friendship: With Oscar.
- Must Have Caffeine
- Odd Friendship: Again, with Oscar.
- Sense Freak: After regaining his sense of smell that he lost as a child.
- Babies Ever After: Karen marries a soldier and is pregnant by the time of The Movie
- Berserk Button: Don't imply Karen is stupid.
- Brutal Honesty: When others seek her for advice.
- Dumb Blonde: Averted, though it's a Running Gag.
- Fair Cop: Tara Spencer-Nairn looks quite dashing in that uniform.
- Feminine Women Can Cook: She hides the fact that she's a good cook because she feels people will respect her less as a police officer if they knew.
- Pregnant Badass
- Women Are Wiser: Downplayed. She's the Straight Man for Davis and is one of the more sensible characters, but her inexperience on the job or other quirks often hold her down. She's a much better cop than Davis, but that's still not saying much.
Fitzy is the mostly ineffective mayor of Dog River. He often frets about losing his position, despite the fact that no one ever runs against him. He shows up whenever a government-type decision needs to be made.
- Clueless Boss
- Cutting Corners: He's not particularly cheap, he's just awful at managing the town's money, so he does this out of necessity. For example, his "desk" is just a wooden door laid on top of two filing cabinets.
- Even Bad Men Love Their Mamas: He may be an idiot and completely incompetent at running the town, but he does love his Grandma
- Obstructive Bureaucrat: Sometimes.
- Only Known by Their Nickname: "Fitzy" is obviously a nickname derived from shortening his last name, Fitzgerald. Nevertheless, his office door reads "Fitzy Fitzgerald".
- Pointy-Haired Boss
- Ultimate Job Security: The only reason he's mayor is because he's the only one in town who even remotely wants the job, and nobody ever runs against him.
Interchangeable owners of the only hotel in Dog River, which contains the only bar in Dog River.
- Suspiciously Similar Substitute: Paul was replaced by Phil partway through the series, with no explanation whatsoever.
Lacey's cook and busboy at The Ruby.
Owner of a liquor/insurance store in town
- Disappeared Dad: Accidentally finds out from Brent that his dad died performing a Heroic Sacrifice in the Korean War. The town had told him his dad had joined the circus.
- Killed Off for Real: Due to his actor's death, Wes passes away in the animated series
- The Bus Came Back: Was absent for a while, leading to some Epileptic Trees springing up about his fate. Lampshaded in the show.Hank: I thought you died or moved to Winnipeg or something.
Wes: Nope. I've always been here. You guys just didn't seem interested in calling me.
- We Sell Everything: His store sells the bizarre combination of liquor and insurance. Truth in Television, as an actual store like this exists in the town the show is filmed in (which is where the show got the idea).
Fitzy's Grandma. Real name Helen Jensen.
- Everyone Calls Him "Barkeep": Is known only as "Fitzy's Grandma" until the second-last episode of the entire show.Karen: The winner is... [confused] Helen Jensen? Who's that?
[Fitzy's Grandma steps forward]
Karen: [surprised] Oh. The winner is Fitzy's Grandma. Helen, apparently.
- Hank does call her Old Lady Jensen in "World's Biggest Thing", but her first name isn't revealed until later
- Innocent Innuendo: She comes up with the idea for the town to build the "World's Biggest Hoe", as a reference to Dog River's agricultural heritage. She doesn't get the negative connotation until she overhears Davis make a joke about it later.
A little white-haired woman and town local. She, Emma and Fitzy's Grandma make up a sort of "old lady triumvirate" that serve on every Dog River town committee.
- Hidden Depths: She's good enough at curling that Oscar and Emma are willing to bring her on their team even though she just had hip replacement surgery. The team ends up winning the whole tournament.
