While I wish it wasn't necessary to go take these steps, the cost of going to a different country for an abortion are much smaller than you imply.
The total cost to get a surgical abortion in Canada is at most USD 5,000. That includes flight, hotel, the procedure, and going back to Canada for a checkup after 2-3 weeks. That's still a lot of money but not take a second mortgage money.
Depending on the exact clinic and circumstances the total for a surgical could be closer to USD 2,500.
If you notice the pregnancy early and can get a medical abortion the total cost is below USD 1,000 and that includes 3-4 nights in Canada so you don't have to take any medication into the US.
Again having to go through this is bullshit and it is still more money than some can afford. But I don't want anyone reading your comment to think it costs tens of thousands of dollars to get an abortion out of the country.
