Liberal MP Jim Karygiannis is quitting the federal political arena after 25 years to enter Toronto municipal politics.
The controversial MP says he intends to run for city council in Ward 39, which overlaps much of the Scarborough-Agincourt riding he's represented since 1988.
He'll file his nomination papers on Wednesday morning.
The current councillor in that ward is Michael Del Grande, who already announced he would not be seeking re-election.
He'd been criticized in the past for speaking harshly to staff and civil servants.
Karygiannis says his decision was prompted by a desire to spend more time with his wife, five grown daughters and elderly mother, while continuing to defend the interests of his constituents.
However, the 58-year-old may also have concluded that his talent for bare-knuckle organizing, employed by both Jean Chretien and Paul Martin to secure the party's leadership, is unlikely to be valued by Justin Trudeau.
The new leader has declared he won't tolerate the nasty infighting that he believes contributed to the decline of the once-mighty Liberals into a third-party rump.
Trudeau's team sent a strong signal on that front last month, barring Christine Innes from running for the Liberal nomination in Toronto's Trinity-Spadina after receiving complaints about alleged bullying and intimidation tactics by her husband, former MP Tony Ianno.
