If your business stops operating or the partner or proprietor dies, you should do the following:

$2$ points

Remit all CPP contributions, El premiums, and income tax deductions withheld for the former employees to your tax centre within seven days of the day your business end

Give copies of the T$4$ or T$4$A slips to your former employees

Issue a ROE for each former employee. You generally have five calendar days after the end of the pay period in which an employee's interruption of earnings occurs to issue a ROE to former employees. Employees can view their ROE using their My Service Canada Account. For more information, see Record of Employment $($ROE$)$

all of the above is correct
