Quebec Premier Jean Charest is promising to do whatever he can to block the kind of Senate reform being proposed by Conservative Leader Stephen Harper.

Speaking on Monday in Ottawa, Harper said his plans to reform the Senate are full of "common sense" and that he will proceed with the proposals if his Conservatives are re-elected next week.

Charest, who was in Vermont on Monday to meet with the state's governor, James H. Douglas, said any unilateral attempts to reform the upper house would be met with stiff opposition in Quebec.

Harper has spoken about the need to have elected senators whose maximum term would be eight years.

Quebec and other provinces have argued that both of those planks are unconstitutional.

The provinces maintain that significant changes in one of the country's primary parliamentary institutions can only be achieved by a full-blown constitutional amendment approved by at least seven provinces representing 50 per cent of the population.
