MacNeil qualified for the
2010 PDC World Darts Championship by finishing fourth in the North American Order of Merit. In the preliminary round, he defeated
Guyana's
Norman Madhoo 4–2. In the first round, he lost 3–2 to
Alan Tabern. He represented Canada with
John Part in the
2012 PDC World Cup of Darts and together they reached the second round by defeating Hungary 5–3. MacNeil then beat 15-time World Champion
Phil Taylor in his singles match, but they would eventually succumb 3–2 to the English duo of Taylor and
Adrian Lewis, having lost a sudden death leg. In June MacNeil lost in the final of the Canadian Open to Terry Hayhurst. MacNeil entered Q School in an attempt to win a PDC Tour Card to play the full circuit in 2013 and 2014 and succeeded on the first day, defeating David Copley 6–2 in his final match. He dedicated his success to his late father who had died a month earlier. MacNeil did not play in his third
World Cup of Darts as
Jeff Smith had overtaken him in the Order of Merit as Canada's second highest player behind
John Part. In May, he matched his best ever result in a PDC event by reaching the last 16 of the fourth
Players Championship courtesy of wins over
Wayne Jones, Nick Fullwell and
Paul Nicholson, before losing 6–4 to
Jamie Caven. MacNeil lost 9–8 to
Ronnie Baxter in the third round of the
UK Open. He did not play in a PDC event throughout the rest 2013 and the whole of 2014. MacNeil returned to Q School in January 2015 and was defeated in the final round on day three by Jason Wilson. However, after all four days had been completed he finished second on the Order of Merit to earn a new two-year tour card. At the
World Cup, MacNeil and Part lost 5–4 to New Zealand in the first round. He qualified for a couple of European Tour events in 2015, but was knocked out in the first round of both. MacNeil lost 6–3 in the opening round of the
2016 UK Open to Rob Cross. He failed to get beyond the last 64 of an individual event this year. Their second round match with Wales went to a doubles decider after Part beat
Mark Webster, but MacNeil lost 4–0 to
Gerwyn Price. Canada won it 4–2 to move into the quarter-finals, which again went to a doubles match after Part beat
Brendan Dolan and MacNeil lost 4–0 to
Daryl Gurney. Northern Ireland would win the game 4–1. With his PDC tour card status now expired, MacNeil played in 2017 Q School, but didn't get past the last 64 on any of the four days. ==World Championship results==
