🔥 KATIE GRIFFIN! 🔥
Toronto born Katie Griffin has had a successful acting career on both the large and small screen since her 1992 debut as Dede in Are You Afraid of The Dark – Tale of The Prom Queen. A student of the American Academy of Dramatic Arts in Los Angeles, Katie’s diverse and unique talent has been featured in a wide array of projects over the years – from the recent gritty Netflix series Grand Army to animated shows such as Go Dog, Go! and Agent Binky: Pets of the Universe on Amazon Prime. One of Canada’s pre-eminent voice actors, Katie has spent the majority of her 30-year career inside a recording booth, voicing commercials, cartoons, and jingles. Katie’s roles include Sailor Mars from the iconic Anime series Sailor Moon, Ruby from Max and Ruby, Alex from Totally Spies and more recently as Sam Sparks in the animated series Cloudy with A Chance of Meatballs, a role which garnered her a Canadian Screen Award nomination. Katie is thrilled about the release of two upcoming animated shows, Superbuns, a role in which she was nominated for the 2024 ACTRA Award for best voice performance, and the newest season of the highly popular Total Drama Island, as Scary Girl (Lauren). She is also very proud to be part of the Gangnam Project playing the role of Julie Shin released in March, 2024. She currently resides in Toronto with her husband and two sons.
No matter where you know Katie from, you don’t want to miss this chance to meet her! We can’t wait to welcome Katie, along with Garry Chalke, Dan Payne, Clare McConnell, & H. Leighton Dickson to ThunderCon 2026 on September 19th & 20th at the Superior Inn Hotel & Conference Centre!

ThunderCon is thrilled to announce our next guest… someone who may be a familiar face to many of you… award-winning author H. Leighton Dickson!
To us, she’s the Mother of the Con, the Gatherer of Geeks, and someone without whom ThunderCon simply wouldn’t be what it is today. For years, Heather has worked tirelessly behind the scenes to help create a safe, welcoming, and fun place where fans of every fandom can come together and celebrate what they love.
Now it’s our turn to celebrate her.
H. Leighton Dickson or simply Heather, as we know her… because we’re on a first-name basis ;)… is coming off an incredible year with the release of her critically acclaimed novel, Ship of Spells. The story follows military mage Honor Renn, who is slowly being consumed by volatile magic. Rescued by the Touchstone—a legendary, sentient ship filled with outcasts—Honor must work alongside her sworn enemy, the ship’s enigmatic elven captain, to find a cure and prevent a crumbling magical barrier from plunging the world into war. Filled with unforgettable characters, impossible choices, and breathtaking adventure, Ship of Spells will keep you turning pages late into the night.
Heather first made her mark as an indie author with her science fantasy series Rise of the Upper Kingdom, followed by the gothic thriller series Cold Stone & Ivy. She later earned widespread acclaim with her award-winning Dragons of Solunas novels, including Dragon of Ash & Stars: The Autobiography of a Night Dragon and Dragon of Sand & Storm: The Autobiography of a Goddess.
Heather has lived a life almost as adventurous as her characters. She studied Zoology at the University of Guelph and worked at the Edinburgh Zoological Gardens in Scotland, where she was chased by lions, wrestled deaf tigers, and bottle-fed antibiotics to polar bears! She’s been writing and painting since she was five years old and even helped pay her way through university by pencilling comics for DC Comics.
We’re absolutely thrilled to welcome H. Leighton Dickson as one of our featured guests at ThunderCon 2026! Whether you’re an aspiring writer, a fantasy lover, or simply looking for your next great read, be sure to stop by, say hello, and discover why her books have captured the imaginations of readers everywhere.
