Yes, it should. But to be on safer side, also upload your individual marksheets. There's absolutely no question of delay because of marksheets in addition to your transcripts, and such a claim is absurd, to say the least.
Only degree is correct.
Logic
When we are completing our WES evaluation online, the payment that we make includes a copy of the report being sent to Immigration Refugees and Citizenship Canada (IRCC). So it makes sense that IRCC somehow has access to World Education Service (WES) evaluation. The only thing they might do is just enter our reference number and there it is - your Education Credential Evaluation (ECA) report gets displayed. And they cross verify it with our degree.
Secondly, the cic website clearly states that it does not require your ECA report but might be asked at a later time (everyone knows what the word ‘might’ means). Also, cic states that transcripts can be submitted if available.
Thirdly, our electronic-Application for Permanent Residency (e-APR) includes the documents that need to be uploaded with each section. So when we receive e-APR, we will know what to do.
Good Luck to all!
. We all thought of getting ITA wit . Score above 456in the month of April and see we are still waiting and we are looking with feared eyes because of age factor dollar rate changing etc etc .... We all have. Reason with our present status because of which we all applied and still we are sitting and dreaming to make our tiny first step 
of receiving an ITA we all know its not end of world but we all wished so much and to be honest I don't know when because of last draw "456 any chance"
