LaborTek is a training and consulting company operating in the National Capital Region. They operate in both official languages and are certified by the Ontario Ministry of Labour. They offer the traditional on-site or off-site face-to-face courses but they are also offering online courses. There is a pretty good selection including WHIMS 2015 and Workplace Violence & Harassment. You can complete the training courses as an individual or a company can sign up for an account.
A this juncture I would say that they are working to develop their online presence through online classes, but that the full selection of their courses is not yet available.
