A sharp-tongued intellectual who shaped Canada's social democratic movement, fighting for a more just society from the backrooms to Parliament Hill.
David Lewis arrived in Canada as a child refugee from tsarist Russia, an experience that forged a lifelong commitment to fighting inequality. He cut his teeth not on the campaign trail, but in the meticulous, unglamorous work of party building, serving as the national secretary of the Co-operative Commonwealth Federation (CCF) for fourteen years. With a lawyer's precision and a polemicist's fire, he was a principal architect in the transformation of the CCF into the broader-based New Democratic Party. As NDP leader in the early 1970s, he wielded influence far beyond his party's numbers, coining the devastating phrase 'corporate welfare bums' to attack business subsidies and holding the balance of power in a minority Parliament. Lewis's legacy is that of the indispensable organizer, the strategic mind who believed power was necessary to implement principle, and who helped embed social democratic ideas into Canada's political fabric.

“The NDP is not a party of protest; it is a party of power, because we want to put our principles into practice.”
