Proof of work experience for Canada Work Permit VISA

Hi Team,

I have submitted online application for Canada WP as supported by my current employer. I received a query to submit Proof of Experience. Actually I have 11 years of total experience: 8.5 in current employer and 2.5 from previous employer. As a proof of experience I have submitted Appointment letter, Letter of reference, last 3 years Form 16, bank statement of last 6 months and payslips of last 3 months from current employer, And the letter of reference include my 8.5 years experience from current employer only. I couldn’t get any letters from previous employer. Can you please suggest if this is fine for my work permit application?
