I drove from NJ to Ottawa by Road with wife & 2 year kid. It was fun driving to Ottawa. Crossing the border both ways was very easy and process was pretty smooth. This is my 2nd H1B stamping from ottawa, last one was in sept 2015.

Interview day:

#Reached Consulate at 08:05 AM after parking car on the street close by. After clearing the security at the gate and appointment confirmation by security personal, we were let in. We did not have any issues taking our kids (US citizen) along with us. DO NOT TAKE ANY BAG PACKS, they won't let you in.
# After getting in I797, Ds-160 were checked.
#Next was 1 more security check, all the electronic devices, water, food were left at the security area.
#Went to first counter for I797, Ds-160, Photo verification
#Sent to counter 4 for Fingerprints.
#Had to wait in line for interview call now.
