"Canadian tariffs" doesn't mean anything please specify on which goods you are referring to. (e.g. lumber, dairy etc...)

The American government is proposing across the board on every import (>=$800 or something) tariffs which has never been implemented by the Canadian government on American goods.

Canada is highly protective of certain industries which are typically small and are engaged in by a large voting population but small portion of the economy (GDP). As a percentage of total goods that American companies might actually want to export to Canada import tariffs are typically quite low.
