The Conservative government seems to have escaped the threat of another federal election after the NDP and Bloc Quebecois pledged their support. But how long will it last?

Simon Fraser University political science professor Patrick Smith told 24 hours Stephen Harper may have bought his government a lifeline until next spring with his EI concessions.

"I don't believe we'll get an election this week, and it's pretty likely [the government] will get through next spring," Smith said. "There will be a lull because no one wants to be campaigning during the Olympics."

But unless Harper starts working out deals with every party, instead of "acting like he has a majority," Smith says it could be a rocky road for the Conservatives.

"There could very well be more votes of non-confidence," Smith said. "Canadians haven't figured out coalition or minority governments yet, but they're learning a bit now."

Smith also doesn't buy the theory the NDP will suffer for supporting a government they're often at odds with.

The EI reforms the Conservatives have agreed on will help NDP supporters in Quebec, Ontario and in B.C. while their cooperation will have "some resonance" with the public.
