can Tax - not find a question/answer exactly matching

I am a Canadian that has recently returned to Canada.

Trasferred to US on an L1A visa in 2004 and recieved Green Card in 2007.

I HAVE USED 3 OF MY 6 YEARS ON MY L1A VISA. i need more than 3 years to keep my job.

lawyer is suggesting that i get a commuter Green Card, but i am getting double talk on taxes.

know of a solid source i can rely on ?? do not want to pay more taxes.

If you return to canada, regardless of your US immig status, you will be subject to Cdn taxes as a resident.
