Registered division

The long-gun registry splits the NDP leadership contenders.

Brian Topp, the Montreal-born Toronto union leader considered by many as a front-runner, said as prime minister, he would attempt to revive the controversial program to register all long guns … Two other urban MPs seeking to replace the late Jack Layton — Peggy Nash of Toronto and Paul Dewar of Ottawa — are also in favour of bringing back the registry…

A fourth big-city candidate, Thomas Mulcair of Montreal, said through a spokesman that he wasn’t at this point taking a position on the issue. Cullen and three other candidates — Niki Ashton of the remote Churchill riding in Manitoba; Robert Chisholm of Dartmouth, N.S.; and Martin Singh of Musquodoboit Harbour, near Halifax — said they wouldn’t bring it back.

Mr. Topp says reestablishing the registry would have to be cost effective. Ms. Nash says it would have to be less onerous. Mr. Dewar says he would register weapons “in a way that consults with stakeholders and finds solutions.”
