Canadian Highlights 2022 Awards: CIGRE Medal – Mohamed Rashwan Could be an issue with number of WGs in B4 as many plan to finish before 2024 and few proposals are being submitted. Opportunity for proposals from Canada. Currently there are 45 Canadian members in a B4 discussion forum. I’m proposing to creating a B4 mirror panel like A2. Anything formal needed? Does CIGRE Canada need a Panel member handbook? Annual meetings could be at CIGRE Canada events.
