While it is mathematically possible to form a minority government without a strong base in either province, but such an undertaking is politically difficult. The Liberals were the only party with a strong base in both provinces, thus making them the only party capable of forming a government. There was some disappointment as Liberals were not able to recover their traditional dominant position in Quebec, despite being led by a Quebecer from a strongly nationalist region of Quebec. The Bloc capitalized on discontent with the failure of the 1990 Meech Lake Accord and Chrétien's uncompromising stance on federalism (see below) to win the most seats in Quebec in every election from 1993 onward, even serving as the official opposition from 1993 to 1997. Chrétien's reputation in his home province never recovered after the 1990 leadership convention when rival Paul Martin forced him to declare his opposition to the Meech Lake Accord. However, the Liberals did increase their support in the next two elections due to infighting within the Bloc. In the 1997 election, although the Liberals finished with a thin majority, it was their gains in Quebec which were credited with offsetting their losses in the Maritime provinces. In particular, the 2000 election was a breakthrough for the Liberals after the PQ government's unpopular initiatives regarding consolidation of several Quebec urban areas into "megacities." Many federal Liberals also took credit for Charest's provincial election victory over the PQ in spring 2003. A series of by-elections allowed the Liberals to gain a majority of Quebec ridings for the first time since 1984. The Chrétien Liberals more than made up for their shortfall in Quebec by building a strong base in Ontario. They reaped a substantial windfall from the votes of fiscally conservative and socially liberal voters who had previously voted Tory, as well as rapid growth in the Greater Toronto Area. They were also able to take advantage of massive vote splitting between the Tories and Reform/Alliance in rural areas of the province that had traditionally formed the backbone of provincial Tory governments. Combined with their historic dominance of Metro Toronto and northern Ontario, the Liberals dominated the province's federal politics even as the Tories won landslide majorities at the provincial level. In 1993, for example, the Liberals won all but one seat in Ontario, and came within 123 votes in Simcoe Centre of pulling off the first clean sweep of Canada's most populated province. They were able to retain their position as the largest party in the House by winning all but two seats in Ontario in the 1997 election. The Liberals were assured of at least a minority government once the Ontario results came in, but it was not clear until later in the night that they would retain their majority.
