Can you show where it says he didn't pay, because right from the story:
"Among the donors was insurance tycoon Shenglin Xian, the founder of Wealth One Bank of Canada, and several Chinese billionaires."
Donor typically means you....gave money.
I would agree that this isn't on the level of a Watergate scandal. However, the fact that Trudeau continues to say they have done nothing wrong, despite the campaign pledges and policies in place, runs counter to the "honest" politician the Liberals are trying to portray him as.
