listen bro, just follow the checklist . There are precise questions about what to mention in your SOP. ( for the study permit )
And, about applying to colleges , you don't have to submit a SOP .
I got admission offer in two universities : University Of New Brunswick and Mount Allison University. and I didn't have to submit any SOP.
Today , I received my Medical report email. Pray for me bro
And, All the best with your application. In Sha Allah, you'll get your visa
