The Job duties should be mentioned in a separate letter.
from http://www.cic.gc.ca/english/pdf/kits/guides/E37023.pdf
For you, your spouse or common-law partner provide:
•notarized employment contracts from your present and past employers, accompanied by an English or French translation
•original and up-to-date
letters of reference from your past and current employers. Letters must be written on company letterhead and show the company’s full address, telephone and fax numbers, and be stamped with the company’s official seal.
Letters must include all of the following information:
•the specific period of your employment with the company
•the positions you have held during the period of employment and the time spent in each position
•
your main responsibilities and duties in each position
•your total annual salary plus benefits
•the signature of your immediate supervisor or the personnel officer of the company
•a business card of the person signing
If you cannot provide a reference from your current employer, provide a written explanation.
Considering above, I think Job Duties/Roles& Responsiblities should go in the reference letter.
Seek for the other seniors advice too
Thanks
