If you have been selected to participate in the Statistics Canada Business Payroll Survey, you are required by law to produce this report at the end of every month.

When you click on the Statistics Canada Report check box to place a check mark in it, you are telling Ceridian that you want a Statistics Canada report printed and sent in your payroll package for this pay. You must sign and submit this report to Statistics Canada.
In general, you'll request a Statistics Canada report on the last pay period of the month. (You have to consistently choose either the last Pay Period Ending Date or the last Payment Date - it doesn't matter which one you choose as long as you always use the same one.)
