The Washington Post website describes it thus:
(Excerpt)
“For many Ottawa residents, the last two weeks of gridlock, horn-blaring, intimidation, and reports of vandalism and hate crimes have been anything but friendly. Bus routes have been rerouted. Roads and businesses are blocked. Confederate flags and swastikas have made appearances. Monuments have been defaced. Far-right extremist groups and right-wing American media have taken up the cause.
The protest was sparked by U.S. and Canadian rules requiring cross-border truckers to be fully vaccinated. But it quickly expanded into a movement against pandemic restrictions more broadly, which are mostly imposed by provinces, and against Canadian Prime Minister Justin Trudeau. The Canadian Trucking Alliance, an industry group, has denounced the protest, noting that the vast majority of Canadian truckers are vaccinated and that many of the convoy’s organizers are not truckers.
But the protesters are confident in their righteousness. Dismissing polls and scientific studies, they say they are tacitly backed by “the silent majority” — as well as millions of dollars raised online from donors, many of whom remain anonymous and some of whom have U.S. ties.”
