The government is planning to give $150 million over five years toward the RCMP, saying the money would enhance the organization's "capacity to conduct criminal investigations related to terrorism."
The funding outlined today was already announced earlier in the federal budget and hasn't yet passed through Parliament.
Harper's announcement comes days after RMCP arrested 10 Montreal youth they believe were trying to leave the country to join jihadists in Turkey and Syria.
He said the new measures would help fight terrorism, adding that "there is no excuse for a Canadian to become a terrorist."
Later today, Harper will also be honoured by Montreal's Jewish Community Council.
The party hopes to make major gains in Quebec in this fall's election.
