ISO 45001 is currently in DIS (Draft International Standard) stage and the final draft (FDIS) will be published in September 2017, while approval and publication of the ISO 45001 is expected in December 2017. There were some complications with the text of the standard so the deadline for publication is prolonged.
Currently, no one can provide e-learning or any other information simply because none of the information about the requirements are official and basically no one knows hoe the standard will look like. Once the FDIS version of the standard is published we will know exact requirements of the standard and then it will be possible to create e-leaning course which we will certainly do. At this moment you can see our free online courses for ISO 9001, ISO 14001 and ISO 27001, they are all available here https://advisera.com/training/ and are made according to the latest versions of the standards.
