How can I get a hold of a full copy of my last years income tax return in Canada?

I did my tax return with Turbo tax last year. But this year I would like to do it with the accountant in Town. They are asking for a copy of last years return and I do not have one with me even thought it was filed with the Canada Revenue Agency. How do I get a pdf copy of last years return in Canada from Turbo Tax? All I can find is a return summary for that year.
