Hello Wajahad,,
Well if u write ur sop in your own words will be more effective,, but I can haelp u a bit ,,
Write down sop in following manner,,,
First paragraph: ur introduction,,, ( u can ur travel history ,, and financials too,, so VO can have a idea about ur application,,,)
2nd paragraph: tell him why u are choosing Canada.,, find some point on internet
3rd paragraph: tell him why u are choosing any particular institution,, u can find ur institution qualities on their website
4th paragraph: tell him why u r choosing any particular course and how it resembles ur previous studies,,
Last paragraph: tell him about future plans,, like after completing ur course how it will benefit u in your home country,,
Thats all u need to describe,, write a good 700 to 800 words sop and ur good to go,, u can read few sops on internet but never copy it,,
