In the referendum to ban the new construction of minarets in Switzerland, 57.5 percent of Swiss voters supported the ban. Also, voters 19 1/2 cantons out of 23 voted "yes" and supported the ban. Had the Swiss referendum used the rules under Ontario or British Columbia's referendum law, it would have failed to achieve the 60 percent threshold for passing.
Whether 50 or 60 percent of the voters should agree in a referendum or if a referendum should have taken place at all, that is something that people can discuss.
I'm still trying to figure out the half-canton thingy.
