FACTBOX-Canada's Prime Minister Harper on political crisis

Dec 3 (Reuters) - Canadian Prime Minister Stephen Harper will use "every legal means" to block a plan by opposition parties to replace his minority Conservative government, Harper said in a nationally televised address on Wednesday.

The following are highlights of his speech:

"Tonight, I pledge to you that Canada's Government will use every legal means at our disposal to protect our democracy, to protect our economy and to protect Canada."

"The opposition is attempting to impose this deal without your say, without your consent, and without your vote."

"This is a pivotal moment in our history."

"At a time of global economic instability, Canada's government must stand unequivocally for keeping the country together. At a time like this, a coalition with the separatists cannot help Canada."

"We are undertaking due diligence on any further requests for assistance from the auto industry. We are increasing support and incentives for manufacturers, the forestry sector and others to pursue business opportunities."

"Next month on January 27, we will bring in a budget which will contain additional measures to boost Canada's economy, while making sure we avoid a long-term structural deficit in Canada's finances."

"Further personal and business tax reductions are coming into effect; We are doubling spending on infrastructure; We are ensuring credit for businesses and consumers by injecting liquidity into financial markets..." (Reporting by Louise Egan; Editing by Cynthia Osterman)
