This will be Falkovsky's first year of professional hockey. The 6-foot-7 rearguard spent the 2015-16 season with the Ottawa 67's in the Ontario Hockey League, scoring nine goals and 32 points in 58 games. In five postseason appearances, he registered one goal and three points.
Falkovsky also competed in the 2016 IIHF World Junior Championship with Belarus, netting one goal and two points in six games.
Jeff Brown, who coached Falkovsky in Ottawa last year, has confidence the 19-year-old has the tools to make the transition to the pro game.
"He was a fish out of water when he first came here, having to adapt to the North America game and the speed of our league," Brown told CalgaryFlames.com earlier this summer. "But he's a smart kid and a smart player who, after realized he couldn't rely just on his long reach, started to move his feet and he became a very effective player for us after that.
"He adapted well at this level and I expect he'll do the same at the next one."
Last month, Falkovsky participated in the Young Stars Classic with the Flames and attended Calgary's training camp. He was assigned to the Stockton Heat on Sept. 28.
The Heat open the 2016-17 season on Oct. 15 when they host the San Jose Barracuda at the Stockton Arena.
