I recently received this question and managed to find some useful resources to share. So I thought I'd share them here as well.
You might find this report of interest:
What’s Possible: Leveraging Emerging Technologies for Occupation-specific Language Training and Helping Clients Transition to Work (2021)
This report summarizes an IRCC-funded Service Delivery Improvement (SDI) project that focused on emerging technologies and helping clients transition to work through Occupation-specific Language Training (OSLT) and Formation linguistique axée sur les professions (FLAP). The report includes details about the activities undertaken by Colleges Ontario and the 12 participating colleges as well as what was learned and how it could be applied to ongoing OSLT/FLAP delivery. It also includes information about the guiding design principles developed during this SDI project – ideas that curriculum developers could consider when developing and planning the delivery of online language courses.
They have additional useful information here.
The Alberta Association of Immigrant Serving Agencies (AAISA) has done some useful research looking at best practices in a number of areas, including employment services, with more here and here. They have language-related summaries here, here, here, and here.
They put together some relevant capacity-building resources you might find useful, including language teaching and employment-specific tip sheets. These include useful insights of different modes of service and learning - in-person, remote, hybrid, and hyflex.
They've also got a related self-directed course: Digital Literacy and Equity in Hybrid Learning with Low Literacy Learners. You need to create an account in order to access it.
I would recommend reviewing resources on Tutela.ca, checking with TESL, the various colleges that offer OSLT courses/programming, as well as LearnIT2Teach which supports the broader language instruction sector (they also manage a very useful Adult Settlement Blended Language Learning: Selected Annotated Bibliographywebsite - here's a quick relevant search).
