In the 1995 BDO World Championship, Part only won one match in defending his title; losing in the second round to Paul Williams.

Part comfortably advanced through the tournament until the semi-final, where he defeated Essex veteran Rod Harrington 6–5 to reach his first major PDC final.

[17] Taylor's performance, described as 'ludicrous' by The Guardian,[18] while simply regarded by darts commentator Sid Waddell as a 'vicious example of near perfection' and an 'annihilation',[17] could have seriously affected Part's confidence.

Over the next two years, Part won a string of minor titles, rose to number two in the world rankings and developed a rivalry with Taylor that would define this stage of his career.

Part recorded another victory over Taylor in the 2003 Las Vegas Desert Classic semi-final, but lost in the final 16–12 in legs as Peter Manley took the crown.

[11] Despite Taylor regaining the PDC World Championship, Part once again defeated 'The Power' in the 2004 UK Open quarter-final, with an 8–6 win.

This statistic, combined with the unsuccessful Premier League campaign and the two world championship losses to Dudbridge, made this a less fruitful period for Part, reflected by his slide in the rankings.

He reached three semi-finals of televised majors: US Open; the World Grand Prix, and the Las Vegas Desert Classic (though he could not defend his title in the latter).

In the semi-final he faced Kevin Painter, reminiscent of his 2003 triumph; Part once again emerged victorious, 6–2 this time, and found himself in his fourth world championship final.

[36] In a tournament where the contemporary superpowers of the game had faltered – Taylor had lost 5–4 to Wayne Mardle in the quarter-finals and reigning champion van Barneveld had been eliminated by Painter in the third round – a 500–1 rank outsider would face Part in the final.

While Shepherd had shown remarkable guile, moxie and perhaps good fortune in defeating stalwarts of the PDC's top 10, including Mardle, Peter Manley, and Terry Jenkins, the experience of Part proved a step too far.

He thus joined Taylor, van Barneveld, Eric Bristow and John Lowe as the fifth player to have won more than two world championships.

Initially, Part enjoyed some success; just as in 2003, he won the first tournament he entered as world champion with a victory in the Gibraltar Players Championship.

Part was defeated by Kirk Shepherd in the second round of the 2010 World Championship in a repeat of the 2008 final, only recording a 76 average in a 4–1 loss.

In June 2010, Part came through a large field of players to win the PDC North American Darts Championship in Las Vegas.

[44] Part represented Canada with Ken MacNeil in the 2012 PDC World Cup of Darts and together they were beaten 2–3 by England in the second round, having lost a sudden death leg.

Wins over Kim Huybrechts, Gary Anderson, Mensur Suljović, Simon Whitlock and Adrian Lewis saw Part progress to the final where opponent Stuart Kellett was waiting.

[47] At the European Darts Trophy in Sindelfingen (Germany) Part reached the quarter-finals after defeating Vincent van der Voort, Robert Thornton and Ronnie Baxter.

At the seventh UK Open Qualifier in April, Part won seven games to reach the final which he lost 2–6 to Kim Huybrechts.

[49] He qualified for the European Championship and lost in the first round 4–6 to Kevin Painter, despite hitting a 170 checkout and having a dart at the bullseye for a second one to lead 5–4.

He entered the 2014 World Championship as the 25th seed and played Mareno Michels in the first round, he won the first two sets of the match and then started to struggle with scoring and finishing.

His success in Qualifying School did not transfer to his 2017 season, where he did not progress beyond the last 32 stage of a singles event, taking just £2,250 in prize money in the calendar year.

[55] His best showing of the year was at the World Cup of Darts, where he lost in the second round to the Austrian team with his partner, John Norman Jnr.

[56] The £750 prize money for this was enough for him to qualify as one of the 128 players to take part in the televised stages of the tournament, his first since the 2015 UK Open three years previously.

The £11,500 prize money he collected for this result is his highest earnings from a single event[59] since the 2013 PDC UK Masters,[60] also held at Butlin's Minehead.

He was invited to compete at the inaugural tournament the 2022 World Seniors Darts Championship and was seeded into the second round due to his career's success.

[citation needed] He played his first TV match since 2018 against the 2001 BDO World Darts Championship winner, John Walton in which he lost 3–1 in sets averaging 74.68.

[citation needed] Part was then invited to compete at the 2022 World Seniors Darts Matchplay losing to Peter Manley in the first round in extra legs.

This knowledge is essential to a darts commentator and contributed to Part being chosen by the BBC to join Green in the commentary box during the latter stages of the 1995 Embassy World Championship.

Part continued to commentate on the BDO World Championship even after he started playing in the rival PDC event shown on Sky Sports.
