Hi Annie (from Ottawa ON!)
second opinions are tricky in Canada
Easiest way I've found is to go to your GP and ask them to request it with the person you want to meet. Though I would start chemo while you're waiting. Several people here have had HIPEC and Steph had it in Toronto region. I'll see if I can PM you both in one message
The emotional stuff is it's own thing
Seek out the help of a counsellor. IMO its hugely helpful.
