North of the United States, the political scandal roiling the government does not involve accusations of collusion with Russia or payments to keep an alleged affair quiet.

No one has flown first-class for personal trips on the Canadian taxpayer’s dime, and no one has been accused of anything illegal.

To Americans who have grown used to news about possible obstruction of justice at the top levels of government, the scandal’s questions about corporate influence, the rule of law and a leader’s reputation might seem quaint (or at least very Canadian).

Yet Prime Minister Justin Trudeau has seen his top adviser and two cabinet ministers resign — including a former justice minister who accused his office of “veiled threats” — raising the possibility of a caucus revolt. He faces an ethics investigation into his conduct and, possibly, an independent inquiry.
