When she was a kid, maybe. Politico reports:

Sarah Palin told a Canadian audience Saturday that, as a child in Alaska, her family brought her across the border for medical care under the single-payer Canadian system.
“We used to hustle over the border for health care we received in Canada,” she said, in what the article describes as a reference specifically to Saskatchewan. “And I think now, isn’t that ironic.”
The context doesn’t make clear what Palin is saying is “ironic,” though it may be the fact that she now considers the Canadian system dangerously flawed.
