Canada

TL;DR: if you're an adult and live within transit distance of a hospital in Vancouver, Calgary, Toronto, or Montreal, the costs are probably manageable. For anyone else though, it's not.

Honestly, this sounds low.

My niece was diagnosed with stage IV neuroblastoma at 8 years old. She lives in Peachland, roughly an hour from Kelowna, and about 5 hours from Vancouver. Her parents both work, and one had to either give up work altogether so my niece could be accompanied to Vancouver for weeks and months, while the other worked the few days they could in the Okanagan then drive down to the cost to be with their daughter while she was on chemo.

The costs were brutal. Transport was a big one, and since they both ran their own business, both companies cratered. They stayed at Ronald McDonald House for much of their time in Vancouver (thankfully) but they couldn't stay the whole time and had to pay Vancouver rents for the remainder of her treatment.

They have two kids, so the other needed regular care. This was handled by her retired grandmother, who moved to Vancouver and took a job so she could help out.

My niece survived and is now turning 12. She's just been diagnosed again though, so they're all back on the treadmill. Thankfully this time it was found a lot earlier, so the prognosis is a lot better. She may only need to be in Vancouver for a short time this time.
