How long does OPNP take for WP holder

[jgd]

Dear Friends

I came to Canada in Intra company transfer in March 2014 ,on a work permit(valid till Dec 2016). I work as operations manager(engineering) in aerospace industry .Prior to this I was working for same company in middle east.

Since I have completed one year in my current job I was thinking of applying for OPNP since I dont want to get into LMIA process( to apply in Express entry).

Appreciate if experienced members can let me know how long it takes to get PR in OPNP route ?

Thanks
