Hmm, this is a complex one, two basic methods, if you want to file as residents of Canada, you need to file a 2555-EZ to report your income (if any) to the IRS from the date you moved your tax home (if in fact you want to move it), this income is excluded from your US taxable income. You can't file jointly in the US for 2008 because your husband is a non-resident alien and you are a US citizen. Your husband would need to file dual status.
However, if you're only going to be in Canada for five months, it might be better to try filing as non-resident for the whole period if the CRA and RQ will let you, although it's hard to do when you're Canadian citizens living and working in Canada, although this may be an exception given your long stay in the US and the fact you're a US citizen.
What this would mean essentially is that you would carry on filing a joint 1040 as per usual and claim a foreign tax credit on Form 1116 for the Canadian tax.
I'm not terribly clear on what the filing requirements are on the Canadian end for non-residents of Canada anymore because they keep messing about with them, but you would need to file a pro-rated T1 of some description for the last month of 2008 as well. I think it used to be a non-resident T1 but I think now it's just a regular T1, check with the CRA. On his TD-1 he needs to declare to his employer that he is non-resident as well.
I get the impression that your husband is a US LPR, if so then he MUST file as a US resident, if he moves his tax home to Canada it can have serious consequences for his LPR status, i.e. he will lose it.
As non-residents for tax purposes, you cannot establish any significant residential ties either, otherwise the CRA will consider you resident. So no healthcare, keep your US DLs, etc.
