NewViews can create Canadian XML E-files for T4, T4A, T5 and T5018. See Filing T4/T5 and other types of returns for more.
Here is an example of exporting Relevé 1 information from NewViews to a third party E-filing package called AvanTax eForms 2015. The following could be used as a guide to export to other third party packages.
