You are correct except for calling the white colonizers “settlers”.
Settlers in this context typically means immigrants who came over after Australia became a British colony. Usually non-white but there are plenty of Scottish and Irish families who are settlers because of the whole British enslaving them part.
The facists and racists have existed before Canada was a country but people just keep conveniently forgetting. Except back then they were the ones in power.
Of course, literal records of Parliament don’t.
