Events Calendar Category Template

I’m trying to get the event category page: https://www.stemcellrevolution.com/2015-site/events/category/training-conferences/

to look like this page: https://www.stemcellrevolution.com/2015-site/events/

…with the sidebar (instead of full width). Is it being controlled by the category or archive.php template?

I’d like it to be in a page template with the sidebar and normal footer like the main events page and all of the other site pages.
