No, because there are other employment categories, such as various other H categories and also L being the main ones. There are other more obscure ones like O.
From what I know, there is no law saying that you can't apply for green card from TN status. However, USCIS can reject your TN renew because you have applied for GC. With the 3 year limit on TN visa, you 1st renew TN, then file GC application, as long as you submit I485 before next TN renew, you will be fine. USCIS will not reject your GC because you are on TN status.
You can apply for AOS if you get a visa number somehow, e.g. through marriage, but your employer cannot sponsor you for a visa number from TN-1 because you must have non-immigrant intent when you enter, whereas H-1B is "dual status" which means you can enter with the intent to stay.
The usual way around it is they put down a Canadian address on the I-140 and you use consular processing. Or change status to some other category.
How soon are you required to leave?
The law doesn't provide for a limit, basically you have to leave immediately however the caselaw I vaguely recall said you have a "reasonable" amount of time to leave which USCIS seem to interpret generally as ten days.
Could you file a change of status to change to visitor status and stay for a few months without physically leaving and re-entering? You can say that you need to either settle your current rental lease or sell your house.
You can file I-539 to do this, however the catch is that if you've already been in the US for more than six months (i.e. longer than the standard visitor limit) they may not grant it. I was expressly told by INS once at a POE that because I'd been in the country in a different category that they wouldn't have let me in as a visitor if I'd already spent six months that year in the US, fortunately I hadn't.
However there have been other people on here who've managed to pull it off, seems to depend on who you get either with CBP or USCIS.
I'm not sure there's much logic to actually filing I-539 because it costs $320 anyway, usually you can get to a POE and re-enter for around that much or less and it's quicker. Although I suppose you could get stranded if they won't let you in. The other problem is that it says on the form to file it 45 days prior to the date you want the change to become effective, so if you lose your job you haven't got enough time to file it.
Just don't make the mistake of overstaying like that guy on here the other day who got denied entry:
