A little off-topic, but something that I just thought of... without the Deep South and with OTL Canada, the Slave Power in the United States will be much, much weaker, to the point where abolition would happen several decades earlier (though the exact date might vary by state) and without a civil war. You'd see gradual manumission and maybe even a stronger *American Colonization Society.
Come the mid-1800s, this could bring radical changes. You see, without the issue of slavery's expansion to divide and later eclipse it, the nativist movement in the United States might end up being much stronger. This would strongly alter the flow of immigration from Europe - I don't know if it'd neccesarily make TTL's Georgia a more attractive destination for immigrants than it otherwise would have been, but it would certainly result in more German and Irish immigration to Latin America and other British settler colonies like Australia, New Zealand, and South Africa.
