How early can someone apply for study permit extension?

[farvahar]

My wife current study permit will expire in June 30 ,2016. I am working in canada on a PGWP and plan to apply to extend my work permit as a dependant to my wife. My current PGWP work permit will expire in April 4, 2016. So, in order to apply together ( her study permit extension + my dependant work permit extension), she has to apply for her study permit extension almost four month in advance (early march). My question is , is there any limit on how early someone can apply for study permit extension? can someone be rejected for applying for study permit extension too early? Has any of you guys had any experience similar to that before?
P.s: Right now, study permit extension processing time is 46 days for online application.
Your toughts on this issue is much appreciated.

Thank you very much for your response. Can I still benefit from so called "implied status" if i apply for extension of my study permit only four days before its expiration? (which is exactly three month before my wife study permit expiration).
