Canada's retaliatory tariffs on American goods took effect just after midnight Tuesday as trade talks stalled. [1] Reuters filed the dollar-for-dollar list as live. [1] An effective date is not a closed border. Print live. Do not print a sealed frontier.

The U.S. dated a ban on certain Canadian alcoholic imports, motorcycles, and dairy for Sept. 29. [1] That is a later clock. Tuesday is September 8. The 8th is not the 29th. Print what is live. Leave the 29th to the 29th.

Oil approaching 100 without clearing it sits on another page. It is not this tariff. Leave a named rollback to the edition that owns a named rollback.

Print live. Tuesday is not the drinks ban. A midnight list is still not a sealed frontier.
