the 2016 United States wireless spectrum auction, WCAX-TV was relocated to UHF channel 20 on October 24, 2019, using PSIP to display its virtual channel number as 3. Viewership in Canada The station has long had significant viewership in Montreal, which is more than ten times as large as its American coverage area. In the past, it has identified itself as serving "Burlington/Plattsburgh/Montreal" to acknowledge its Canadian viewership, though this practice largely ended in the 1990s. Like other Champlain Valley stations, WCAX-TV once made a significant portion of its advertising sales across the border. However, Canadian advertising business has nearly dried up mostly due to the arrival of English-language station CKMI-DT-1, coupled with the Canadian simultaneous substitution regulations and the carriage of network affiliates from other United States markets (such as Boston and Detroit) on Canadian satellite and cable systems. Canada also discourages Canadian-based businesses from advertising on U.S.-based stations by not allowing tax deductions for commercials placed on stations outside of Canada.
