When TeenNick’s promo said Degrassi will return this October, they really meant it will return as early in October as possible:
The tentative dates for Degrassi this fall are the 13B premiere airing on October 3rd, and the finale airing on November 21st (8 weeks). Just like Stephen Stohn said before season 13 began, it looks like Degrassi will remain on Thursdays this fall, and it’ll also stay in the 8pm timeslot in Canada. For now we can also assume TeenNick will continue to air Degrassi on Thursdays at 9pm.
I can’t give you a definitive airdate schedule beyond the premiere because the Stohn said there will be more one-hour episodes throughout the season. However, we do know that at the bare minimum we’ll see episodes 1309-1316 (most of which their episode titles are still unknown).
There also seems to be an interesting bit of news that will affect Canadian viewers this fall, but I’ll leave the higher powers that be announce that news when they’re ready.
