Not really, hasn't been a single genocide since federation and there's not going to be.
Also, the fact that genocide occured was not due to the morality of white people, but rather an imbalance of power that existed and the times people lived in. Aboriginals in Australia simply lacked to capability to enact anything such as colonialization or genocide rather than anything resembling higher morality on their part.
In the end all races are capable of genocide and the past is the past. Saying to someone "your ancestors did bad things therefore bad things happening to you are justified" is in itself a racist statement that holds no water in todays world.
White immigrants did not treat the native populations well upon their arrival for the most part is true but that does not mean that immigrants that won't behave in an acceptable manner in the 21st century who want to go to Canada should be allowed to.
Whether it was before or after Federation doesn't matter.
And it was absolutely an issue of morality; white colonists knew exactly what they were doing when they massacred Aborigines. But they did it anyway, because they believed that murdering people of "inferior" races was justified.
And I never said "your ancestors did bad things therefore bad things happening to you are justified". I merely pointed out the inherent irony.
It would be ironic if the people who commited genocide were the ones wanting to keep people out because they though they were dangerous.
The people currently in Canada are not responsible for the past genocide their ancestors commited in any way.
Also, as a point of note, all people have ancestors who commited genocide as homosapiens commited genocide against the neanderthals.
