Sheep Island is a demanding reef and wall dive located 1000 metres off the coast of Victoria, Canada. The site features depths ranging from 9 to 40 metres, with an average depth of 20 metres. Divers must contend with strong currents that can shift unexpectedly, making this an advanced site requiring drift diving experience. Visibility is variable, typically between 4 and 15 metres. Water temperatures remain cold year-round, fluctuating between 8 and 11 degrees Celsius, necessitating the use of a drysuit and hood. Access is strictly by boat, and divers should plan entries around slack water to manage the challenging current conditions.

Reay Island is a boat-accessible reef and wall dive located off the coast of Victoria, Canada. The site features a vertical profile descending from 8 metres to a maximum depth of 30 metres, with an average depth of 15 metres. Divers should expect strong currents, making precise timing around the slack tide essential for a successful 50-minute dive. Visibility is typically limited to 6 to 9 metres, and water temperatures remain cold, ranging from 8 to 11 degrees Celsius throughout the year. Due to the challenging current conditions and the presence of kelp forests, this site is best suited for intermediate divers with strong buoyancy control and cold-water experience.

Rubly Island is a challenging shore-entry reef site located in Victoria, Canada. The topography features a significant drop-off, descending from 8 metres to depths of 120 metres. Due to the strong currents and unpredictable surf at the entry point, this site is strictly for advanced divers. Visibility is typically limited to 4 to 6 metres, requiring precise navigation and buoyancy control. Water temperatures remain between 8 and 10 degrees Celsius throughout the year, necessitating the use of a drysuit. Divers must consult current tables to time their entry with slack water and remain vigilant regarding surface boat traffic and the overhead cave environment.

Little Group Islands, located near Vancouver Island, offers a calm, accessible reef dive suitable for beginner divers. The site features a rocky substrate at depths between 4 and 12 metres. Shore entry allows for straightforward logistics, and the site is accessible year-round. Divers can expect visibility ranging from 5 to 10 metres. Water temperatures remain cold, between 8 and 12 degrees Celsius, necessitating a drysuit or a thick, well-fitted wetsuit with a hood. Species recorded around this area include harbour seals, various nudibranchs such as Monterey dorids and Hermissenda, as well as ling cod, king crabs, and Pacific lion's mane jellyfish.

North Cod Reef is a marine site located off the coast of Victoria, Canada. The reef topography spans depths between 5 and 35 metres, with an average depth of 20 metres. Divers should expect cold water temperatures ranging from 8 to 11 degrees Celsius, making drysuits necessary. Visibility typically fluctuates between 5 and 15 metres. Access is by boat only, and the site is suited for intermediate divers due to mild currents and potential hazards including boat traffic and cold water. Species recorded around this area include harbour seals, various nudibranchs, and jellyfish. Divers should deploy a surface marker buoy on ascent and plan surface intervals carefully.

South Cod Reef is a rocky reef structure located in Victoria, Canada, offering depths ranging from 10 to 110 metres. While the shallower sections are accessible to open water certified divers, the deeper areas are reserved for advanced divers. Divers can expect mild currents and visibility between 10 and 15 metres. Water temperatures remain consistently cool, between 8 and 10 degrees Celsius, necessitating the use of a drysuit. Hazards include entanglement risks and sharp coral or rocks on the seabed. Divers should maintain neutral buoyancy to avoid contact with the substrate, where sea urchins are present. Boat access is required to reach this site, and no amenities are available.
