Diving Safety Recommendations

Parks Canada, in co-operation with the sport diving associations and training agencies, supports and encourages all divers to adhere to safe diving practices, including:

  • Certification: All divers should be trained and certified by a recognized organization;
  • Never dive alone: The buddy system offers additional protection in the event of unexpected problems;
  • Cold water: Low water temperatures in this area can create special hazards; only properly equipped and experienced divers should exceed 18 m ( 60 ft.) in depth;
  • Drugs and alcohol: The use of drugs or alcohol when diving can have disastrous effects;
