Scholarship rejection | Should I tell Supervisor So I applied to an MASc program in Canada where basically the supervisor approves students to admit. I applied for a separate departmental scholarship and got rejected. Is it a good idea to tell the supervisor about this? 
Supervisor said he hasn't sent out the final decisions to the graduate studies department and he'll decide in a month. Also, the scholarship I applied for is separate from the funding that he provides.
My point is he did not specifically ask for me to apply here. I initiated it and he told me I could try. Would complete transparency in this case help me or kill the chances I have?
Speaking as a Canadian academic, who also sits on a graduate committee. These decisions are separate, as you note, and I would not feel obligated to mention this to your supervisor. He might or might not know the outcome of these scholarships, depending on how engaged he is with the program's funding picture. 

My advice in this circumstance would be to wait for the admissions decision.
