They say taxation is onerous in Canada, but I think if you factor in all your overhead expenses and frustrations here later on, you will see that taxation is not that bad at all in Canada.
And again, depending where in the US you decide to live, the tax burden can be just as heavy as back home in Canada, and with far fewer public services to show for your money. Here in North Carolina we pay both federal and state income taxes, plus we pay ANNUAL property tax on our CARS!, plus our homes, and and and. We're nickle and dimed to death really, and there is absolutely NO public services where we live. Our property
taxes and other fees just go up and up and up, and they just keep taking away services.
Plus, on every paycheck we get dinged for Medicare, and being a sponsored immigrant myself, I'm not eligible to use it

My monthly
health insurance premiums are ghastly, and we still have to pay for medical services on top of that. They call it "co-pay"

Wait times for specialists aren't any better here than they were back home either. And quality of care is actually quite frightful.
Others may have differet less scary experiences in other parts of the US, but health care in general is A LOT different, and VERY EXPENSIVE here. If you don't have insurance you can end up bankrupt if Gods forbid, you have a horrible accident or get deathly sick. My husband had cancer a few years ago and had to sell his house to pay the bills. And he had insurance!
I too would go home in a heartbeat. But alas, my hubby is American and was deemed inadmissable by Canadian immigration

So we're kinda stuck here.
