British Columbia Conservative MP John Reynolds has stepped aside as the party's House leader Monday after deciding he won't run in the next election.

He will serve as chairman of the party's national campaign during the next federal election, said Conservative Leader Stephen Harper in a statement outlining changes to his caucus team.

The statement was issued on the first day of a three-day federal caucus retreat in Victoria.

"John has been a steadfast Conservative, a consummate politician, and a great friend. While we will miss his presence in the House following the next election, Canadians have been fortunate that a man of his calibre has dedicated himself to public service for so many years," said the statement.

In federal politics since 1972, Reynolds has represented his West Vancouver-Sunshine Coast riding for the Reform party, the Canadian Alliance and the Conservatives. He served briefly as leader of the official Opposition.

B.C. MP Jay Hill will replace Reynolds as House leader.

Hill "has a solid understanding of the House of Commons, and a no-nonsense style that will be beneficial in his new capacity," said Harper.

Niagara Falls MP Rob Nicholson replaces Hill as Opposition whip.

Other changes to Harper's caucus included naming Ontario MP Helena Guergis as deputy critic for seniors' issues and B.C. MP James Moore as critic for both transport and amateur sport. Moore is also the public works critic.
