One person was killed in a shooting Tuesday night when Quebec's separatist leader was addressing supporters over her party's victory in a provincial election.

One person was killed, one injured and a man wearing a bathrobe was arrested, local police said.

The incident occurred at Montreal's Metropolis concert hall where Pauline Marois, leader of Quebec's separatist party Parti Quebecois (PQ), was delivering a victory speech to supporters.

Marois was rushed off the stage without hurt after a pistol was fired, prompting quick response from security staff.

The PQ won Quebec's 40th election on Tuesday. Although the pro-sovereignty party appeared to fall short of the 63 seats required to hold a majority in the 125-seat legislature, it was expected to form a minority government.

Marois, 63, will become the 30th - and first female - premier in the the predominantly French-speaking Canadian province since 1867, when Canada became a country.

According to projections of local media, the PQ defeated incumbent Premier Jean Charest's Quebec Liberal Party with 54 to 50 seats.

The Quebec Liberal Party won three consecutive elections since 2003 and has traditionally supported federalism, meaning it is in favor of keeping Quebec within the Canadian fold.

The PQ's victory dealt a heavy blow to the Liberals, whose nine-year outgoing premier lost to a PQ candidate, in his own riding of Sherbrooke.

With a minority government, Marois will be forced to deal with issues related to Quebec's struggling economy.

The newly-formed Coalition Avenir Quebec (Coalition for Quebec's Future), led by former PQ finance minister Francois Legault, ranked third with 19 seats following Tuesday's vote.

The left-wing separatist party Quebec Solidaire won two seats.

Voter turnout was strong, with more than 52 percent of eligible voters casting their ballots by 5:30 p.m. on Tuesday. In the last provincial election, fifty-seven percent of Quebecers went to the polls.
