For air fills, don't forget:
Ron's Scuba Shop, 13 Eleventh St W, Cornwall, ON (613) 933-1362
Be sure to visit Ron and see his shop, important to note his fill station is no longer at the location and he doesn't do fills anymore. His compressor and bank is at the new o2togo dive shop. It's located on 3045 Pitt street in Cornwall. Anyone remotely close to Cornwall please make the time to visit Ron, he's a gem.
Warm regards,
Cameron
