Hosp(?)
IF it is N.V. (North Vancouver) at that time the hospital was NV General (now called Lions Gate Hospital), but it doesn't say "General". Odd that he would have been taken to North Van anyways. However, at the top of the form, it should say where he was pronounced, above his usual address. It was registered in Vancouver, not North Vancouver, so N.V. might be totally wrong!
Edit:
Here's a link to the Vancouver 1942 directory. I'm not finding anything that would fit, but my eyes aren't what they used to be!
