Tkaczuk was born in Toronto, Ontario. As a youth, he played in the 1993 Quebec International Pee-Wee Hockey Tournament with Toronto Marlboros minor ice hockey team. He was selected sixth overall in the 1997 NHL Entry Draft by the Calgary Flames. He represented Canada at the 1999 World Junior Ice Hockey Championships, where he won a silver medal and led the team in scoring. Tkaczuk was named to the American Hockey League's All-Rookie Team the following season. He played in the National Hockey League for the Calgary Flames during the 2001–02 campaign, but returned to the minors and never saw NHL action again. Tkaczuk left the Flames system at the end of 2000–01 after winning the Calder Cup when traded along with Fred Brathwaite, Sergei Varlamov, and a 2001 ninth-round pick to the St. Louis Blues for goaltender Roman Turek on June 23, 2001. He would then play two more years in the AHL for the Worcester IceCats and after being released by the St. Louis Blues, for the Bridgeport Sound Tigers. Unhappy with his shaky status in the minors, he tried his luck in Europe, spending the 2003–04 season with Lukko of Finland's major league, the SM-liiga, where his numbers were respectable, but not impressive enough to earn him a significant profile in Finland. Tkaczuk then turned to Milan, the highest paying club in the Italian league, where he enjoyed considerable success, maintaining his preeminence even during the 2004–5 season, when the squad was strengthened by the arrival of NHL players during the NHL lockout. He led Milan in goals, assists and points during the regular season and playoffs, good enough for third place overall in Serie A scoring. Thanks to those solid numbers, Tkaczuk was one of three Milan players, along with defenceman Marc Savard and veteran forward Ryan Savoia, named to Team Canada's roster for the 2004 Loto Cup in Slovakia. Milan went on to win the national title, their fourth in a row, defeating Cortina in the finals. In the late summer of 2005, Tkaczuk held talks with Krefeld Pinguine of the Deutsche Eishockey Liga, Grand Rapids Griffins of the American Hockey League, and Lada Togliatti of the Russian Super League before eventually returning to Milan. In 2006, Tkaczuk signed for ERC Ingolstadt of the DEL. In 2007, he moved to EV Duisburg Die Füchse and played there until the completion of the 2008–09 season. Tkaczuk was second in goals during the 2007–08 season. After six years abroad, Tkaczuk returned to North America and signed with the Charlotte Checkers of the ECHL on November 13, 2009. He would later be loaned to the Rochester Americans on December 7, 2009. On January 6, 2010, the Hartford Wolf Pack signed Tkaczuk to a professional tryout contract. Tkaczuk finished the season with 45 points in 46 games for the Checkers. In the following season, Tkaczuk signed a one-year contract with the EC TREND-Dornbirn of the second-tier Austrian National League on September 16, 2010 After scoring 33 points in 26 games with Trend, Tkaczuk signed for the Nottingham Panthers of the Elite Ice Hockey League in the United Kingdom, on January 19, 2011.
