An alternative to email, paper mail and epost, is an actual employee self service portal.

An ESS portal where they can view pay stubs is the ideal option. With a dedicated portal, the employees have their pay stubs and T4s in an organized place. In addition to that, a portal could offer other functions you might need such as sending out memos/announcements, requesting time off and sharing files.
InStaff (https://instaff.org) has a solution for this that can work with Sage 50. You simply upload a batch of paystubs, and it takes care of putting them into each employee's account. You can then send email notifications that there are pay stubs waiting for them.

Epost is a secure employee portal paid for and supported by the Canadian Government. Portals provided by the employer usually incur monthly charges per employee registered. Using epost, there is no implementation or monthly charge to the employer (and is free to the employee)

Security is the responsibility of the Canadian Government. If a person gets unauthorised access to the documents held in someone else's epost account, there is no liability impact on the employer. This is not the case with employer provided staff portals. If passwords are forgotten, the person contacts epost, not the employer.

Epost works well for sending documents like T4s to ex-employees long after they have left the employer. Employees often lose access to employer provided staff portals when they leave the company. This is why most companies revert to sending T4s via the post, if they are not using epost. Epost received documents are kept and accessible by employees and ex-employees for 7 years.

If an employer has a staff portal already, then they probably don't have a problem with current employees receiving documents. They will likely have a problem sending to ex-employees, but the theme of this thread is where there is no staff portal.

In summary, if you are looking for an easy alternative to posting or using insecure email for sending secure pay stubs and T4s to both current and ex-employees, epost is a better solution than implementing your own staff portal.

If you want to solve this problem and you also want to provide self-service HR functions to your current staff, this is where you should consider staff portals - but don't forget the problem of sending documents to ex-employees.

We actually use instaff to send paystubs electronically. It is like a staff portal though it's pretty rudimentary compared to other self service or HR software we were evaluating. Though, we only needed to solve our paystub problem and found the simplicity in this case to be better than some of the more robust options out there, all of which packaged features we didn't care about enough to pay for. Our ex employees can still login to access their pay history after they leave, we just mark them as "inactive" on the backend. ...I think this means if we were using their add-on HR features they wouldn't be able to see those.
