I do not know what you exactly did because I got the Indian RT Permit in the same time. I did my Canadian CPL and RT in February but I submitted it in October and got it in November.
Okay, list me out the exact documents you gave in DETAIL
PM me if you like - Either could be the following reasons - You submitted the photocopy of your RT and not your Original Canadian RT which has the number on it, or you submitted the wrong form or the wrong demand draft or did not even submit the passport book you get for the Canadian CPL which is blue in color.
Please enlist the details and I will tell you what you missed -
Thanks
