NDP Members of Parliament are lobbying the federal government to maintain the 10 ridings in northern Ontario.
The M.P.'s are worried that riding re-distribution might result in fewer members in the House of Commons.
Nickel Belt M.P. Claude Gravelle says they've seen representation in northern Ontario shrink since 1995.
Gravelle says he plans to introduce a private members bill in the House of Commons this week guaranteeing northern Ontario at least 10 Members of Parliament.
