- Jo Grant forgot her encounter with the Eighth Doctor in the 90s in Genocide.
- The nature of her encounter involved the creation an alternate timeline.
- Novels aren't canon, especially if overuled by a television show.
- Not true. Canon is a term that has been constructed by fans. A Doctor Who official once said there was never any sort of canon used by the creators.
- Yes, but canon refers to anything within the Whoniverse. It refers to what counts, as such, and what doesn't, so in a way, every TV show has a canon to distinguish sketches, etc, from the real thing. Novels are generally not considered canoncical, especially, as said above, if they contradict sources that are definitely canon; Doctor Who, SJA and Torchwood.
- Given that the possibilities of alternate timelines and parallel universes, canon is not a necessary thing for Doctor Who. The Doctor's "507" number of regenerations on a spin-off conflicts with the "13", massively. Given Doctor Who is the main show, it would over-ride the SJA comment.

I see your point. However, the "canon" referred to here, I think, was meant to be referring to the main universe the three Whouniverse series are set in. (you are right, the conflicting events of novels, etc, could be true in parallel universes) As for the Doctor's regenerations, as both are in the Whouniverse, us fans will do what we always do; find a reason until a "real" one is explained on screen LOL. I think that, probably, the Doctor was not being serious when talking to Clive, maybe just saying that to impress him, or because his mind was otherwise occupied, etc. Or maybe the previous statement of 13 was a lie... but I, like you, give the main series canoncical priority.
- Wouldn't Sarah Jane object to Tia Karim being in her attic and seeing Mr Smith. Previously she didn't want UNIT to know about him.
- She may have become more lenient, seeing as she has had numerous contacts with UNIT (During the Horath situation, Dalek invasion etc.)
- Seeing as it's evident that UNIT are aware she runs a anti-alien-invading force, that she's bound to have technology in there. But they aren't Torchwood, so they might let her have it.
- Perhaps even the Doctor told them to leaver her alone.
- She could have been so distraught by the news of the Doctor's death that she didn't think about them seeing Mr. Smith.
- I agree, this seems to contradict previous episodes in which Sarah tried to cover up the existance of Mr Smith from UNIT. I think the most logical explanation is that she was in shock, so forgot.
- When the Doctor is talking to Jo, he refers to her, and her grandchildren's, future. Surely this is against his principals to tell someone their future? (hence him not looking at River's diary at the end of the Forest of the Dead) Also, he refers to Jo's happy life... maybe this is (albeit weak) proof that Jo didn't die as a result of a house fire in 2028?
