Response:
You have multiple difficulties here. Firstly, you need to asap get your
green card reinstated. I say reinstated because you may have lost your green
card. Let me explain. If you leave the US without returning for a period of
six months - to one year there's is a presumption that you have in fact
abandoned your green card and your green card could be deemed void. The
proper way to leave the US for an extended period is to first file an I-131
Travel Document this form puts US Immigration on notice that you have to
leave the US for an extended period for what ever reason such as health
education etc but that you have ever intention to return. Once this is
approved you are free to go having preserved your green card status. If you
leave without doing this then you have to take measures to have your green
card reinstated. So my first concern would be to make sure that my green
card is still valid.
If my green card is valid then I can in order to qualify for citizenship you
need to establish 5 years of physical presence in the US, but again where
there has been a significant break in the service the clock can be re-set to
Zero and you have to star over. Any attorney would need to look at all the
circumstances and make a calculation and advise.
The last point I'd leave for now until the first two more serious issues
were resolved. You certainly need to see an attorney.

I had lived in the USA for over 5 years as a permanent resident (8 total). Unfortunately, before I was able to apply for citizenship as the residency requirement was fulfilled, I needed to move back to Canada because of a family emergency. About 15 months later I am looking at the possibility of working in the US and living in Canada.
I have asked the consulate, the local CIS immigration office (I am relatively close to the border), and at one of the local bridges (via telephone) and got different answers from everyone to the following:
Because of the situation being a family emergency, can I still apply for citizenship given my children are Americans, and the 5 year residency requirement was fulfilled? The officer at the bridge said that tax returns, and any supporting documentation proving I lived in the US for 8 years with a letter explaining the situation would allow them to take these circumstances "into consideration" with my application. Is this possible?
If not, I know that going to commuter status of giving up the GC for TN are options - but I have heard that the latter could be perceived as dual intent with mixing immigrant and non-immigrant visas and may get the TN rejected. Has anyone done anything remotely similar?
Thanks!
