How long can I stay in Canada?

[chitwan7]

Hi,
I got visa from 6 August, 2015 to 5 Feb 2015 on my passport.
I came to Canada September 16, 2015.
How long can I stay. One stay can I stay 6 months? If I stay 6 months- 6 months will complete on 16 March 2015. But my visa duration on ppt is from 6 August, 2015 to 5 Feb 2015. Do I have to leave Canada before 5 Feb 2015 or before 15 March 2016.
I am waiting for your response.

Thanks

You can stay six months - unless your passport was stamped with an earlier departure date when you entered Canada.
