McKay Brothers has deployed the lowest latency private bandwidth from Aurora, Illinois to Toronto. McKay’s newest route connects the futures markets at the CME with the cash equity markets of TMX in Toronto in less than 4.3 milliseconds one way. 

McKay’s sister company Quincy Data offers select CME data at TMX. The Quincy Extreme Data (QED) service distributes equity indexes, energy and metals futures at the lowest latency.
  
McKay’s wireless networks have been live in North America since 2012, Europe since 2014 and Asia since 2016. The company’s transpacific network went live last year, connecting the CME with trading hubs in Tokyo, Shanghai, Hong Kong and Singapore at the lowest latency.
