Incident at 5 NW TULOV

Update TSB Report #A18W0095: C-FENO, a Bombardier DHC-8-400 aircraft operated by WestJet Encore, was conducting flight WEN3278 from Calgary Intl, AB (CYYC) to Saskatoon/John G. Diefenbaker Intl, SK (CYXE). During cruise flight at FL250 while navigating around thunderstorm cells, the flight crew observed a TCAS target shown as 1000 feet below them, and on a course set to cross their current flight path. C-FKXC, a corporate Beech B200GT aircraft operated by Regional Aviation Campbell River, was conducting a flight from Medicine Hat, AB (CYXH) to Edmonton Intl, AB (CYEG). The flight crew of C-FKXC requested the authorization to climb from ATC, due to weather. The request was denied as it conflicted with WEN3278. The flight crew of WEN3278 observed C-FKXC begin to climb, and received a TCAS traffic advisory (TA). Shortly thereafter, the TA became a resolution advisory to initiate a climb. The captain disengaged the autopilot and executed a climb until the TCAS advised to level off at FL255. When the TCAS indicated clear of conflict, and after observing C-FKXC pass on the display, the flight crew of WEN3278 descended back to FL250. The flight crew notified ATC of the deviation and subsequent return to their assigned altitude. At no time was WEN3278 in visual contact with C-FKXC.
A Regional Aviation Campbell River Ltd. Beech B200GT (C-FKXC) from Medicine Hat, AB (CYXH) to Edmonton, AB (CYEG) was observed to deviate from assigned altitude by 500ft and conflicted with a WestJet Encore Ltd. de Havilland DHC-8-402 (WEN3278) from Calgary, AB (CYYC) to Saskatoon, SK (CYXE). Separation between the two aircraft was reduced to 3.5NM and less than 600 ft. WEN3278 responded to a Traffic Alert and Collision Avoidance System (TCAS) Resolution Advisory (RA) and began climbing.
