Prominent Canadians called on Ottawa to demand an immediate ceasefire in Gaza in the face of Israel's "war crimes," as others rallied nationwide Thursday in support of Israelis who have been "paralyzed" for years by Hamas missile strikes.

While some 30 protesters marched into the Israeli consulate in Montreal and handed officials a mock eviction notice, a group that included Jewish musicians, academics and activists gathered in Toronto at a news conference to denounce Canada's stance on the latest Mideast conflict.

Those actions preceded rallies from Vancouver to Halifax in solidarity with the people of southern Israel, with a Toronto event at Beth Tzedec Synagogue including a videotaped message from Israeli Prime Minister Ehud Olmert.

"What we're trying to do is something which is the basic and most elementary any country can do for its citizens, which is provide them with security," Olmert said. "We will prevail.

"We'll bring safety and security for the people of Israel and we will always remember that at a time of need, you were with us," Olmert told the Canadian audience.

Earlier in the evening, Peter Kent, a minister of state for foreign affairs in the federal cabinet, told the Toronto audience that the Canadian government is urging the international community to work toward a "durable" ceasefire in the region.

"We continue to be unequivocal in supporting Israel's right to defend itself," Kent said to cheers from about 5,000 gathered at the Toronto synagogue.

Internationally acclaimed concert pianist Anton Kuerti said the "servile" way Ottawa is supporting the U.S. position makes him "ashamed" to be a Canadian.

"The unbelievable war crimes that Israel is committing in Gaza… It makes me ashamed to be a Jew," Kuerti said at the Toronto news conference.

"The servile way in which Canada is supporting the U.S. position — basically it's all Hamas's fault because of missiles that they throw over in desperation — I think this reluctance of Canada to use its influence makes me ashamed to be Canadian."

Israel launched an offensive into the Palestinian territory Dec. 27 to halt repeated rocket attacks on its southern towns.

Nearly 800 Palestinians have been killed — almost half of them civilians, according to area officials — while 10 Israelis have died.

Rallies were held in Toronto, Montreal, London, Hamilton, Ottawa, Winnipeg, Calgary, Vancouver and Halifax to show support for Israelis "paralyzed by thousands of Hamas missiles from Gaza," organizers said.

"I think that Canadians understand that the values of a terrorist entity that is committed to destroy its neighbour are not the values shared by them," said Howard English of the United Jewish Appeal of Greater Toronto, one of the groups behind the rallies.

"I think Canadians understand that people who live in the line of rocket fire every day of their lives cannot go on living that way."
