@ harman- UVic usually takes around 3-4 months for an offer letter... Plus, if u are going for a thesis option, then u should be able to convince a supervisor from the same field. If you have chosen project option or course work, then its not mandatory to have a supervisor.
I applied at the end of Nov and got my offer in the first week of March. My profile is:
10th- 85%
12th - 79%
Btech - 77 % (last 2 years)
IELTS - 8 (R-9, W- 6.5, L- 8.5, S-8)
In addition to this ur SOP should be very impressive and clear...make sure to add all the projects completed by u in ur sop. Make the conclusion by adding a paragraph that indicates why u chose canada as ur study destination and in canada why only UVic... You'll be through it...
All the best
