I remember when I was replacing my Ontario health card, they asked me "Would you like to be an organ donor?" and I didn't hesitate. And now I am registered as such. They made me fill out a quick checklist of what I would like to donate, and I checked everything but my skin and bones.
Logic is, I want my family to be able to bury something lol.

But now that I am thinking about it...is it haram? I'd have the opportunity to save a minimum of 5 lives with my organs...
