Spheric,
First I have no experience in this; I guess winding up a corporation will be as complicated as how large it was.
T2=corporate income tax return
All assets will be deemed disposed at fair market value (meaning possible recapture of CCA/depreciation which is income and or capital gains), if there is significant $$ there, yes you want to talk to an accountant-as the capital gains and some other gains in a capital dividend account could be tax sheltered.
