It's not a strange choice at all, just one that came out of a boardroom, by all accounts Killjoys is a lot cheaper to produce with a small difference in viewing numbers. Same reason Wynonna Earp got renewed and Dark Matter got cancelled. One needs expensive sets and CGI for almost any story they want to tell, one needs 3 seconds of a gun barrel glowing and some eyeliner for it's bad guys.
Plus that business of Dark Matter being a licensed from Dark Horse and Killjoys being created for SyFy/Space.
