Which is better, skilled immigrants to Canada, Australian immigrants or Australian immigrants?

No matter which agency you choose, I suggest that you first understand the ways and means of immigrating to Canada, and then choose the one that suits you. Don't blindly listen to the intermediary, and of course you can't help but listen to the intermediary. So I suggest you familiarize yourself with the immigration process first.
