Even I don't know the refusal reasons. They have left the Final decision field blank. Haven't got any email regarding refusal letter. And it also shows that supporting documents are under review.Usually it is extremely difficult to convince a Canadian Visa Officer when you are trying to pursue a different career from what you have been working for previously. If you can let me know your refusal reasons, SOP and your complete case then maybe I can help you out with some good advice.
I you don't have any problem I want to share the SOP in private message. Any help is highly appreciated.
