eBay-ing in Toronto, Canada

A few things happened. I've moved to Toronto, Canada. I've also started to go with eBay selling as I'd like to widen my client-base to the country and even USA (after getting into reselling at Kijiji.ca and Toronto FB Marketplace). I just don't seem to find enough information on eBay selling in Toronto or maybe I didn't search well enough. I will chronicle my findings here so I can refer to in future.
