How can I delete my canister after I create it

@skyhigh: your canister is on subnet Subnet: o3ow2-2ipam-6fcjo-3j5vt-fzbge-2g7my-5fz2m-p4o2t-dwlc4-gt2q7-5ae - ICP Dashboard which has high storage usage. That’s why operations that allocate more storage/memory require cycle reservation.

We are working with Hot or Not to reduce storage usage on that subnet: Voting for a new IC release - be69c35 - #7 by ulan
