I would like to pretend that the show ended in the classic era, before the sexualization of the reboot. I say would like because I can't decide whether to have my personal canon end right before the Time War ends (possibly including the K9 tv series, due to mostly being disconnected from nuWho) or bypass nuWho entirely and end before 8's regeneration. The reason involves possibly writing crossover fanfic and whether Magic School Bus 360 will be a complete continuity reboot or be in the same continuity as the old show, with different students. (Don't ask)
