Domville Island is a drift dive site located off the coast of Victoria, Canada. The reef topography ranges from 10 to 27 metres in depth, with an average depth of 20 metres. Due to strong currents, this site is suitable only for advanced divers. Visibility varies between 5 and 20 metres, and water temperatures remain cold, between 8 and 11 degrees Celsius. Access is by boat only, and divers must manage hazards including boat traffic, entanglement risks, and cold water. Species recorded around this area include harbour seals, California sea lions, various nudibranchs, and jellyfish. Divers should time their entry to slack water using local current tables.

Sidney Waterfront in Victoria, Canada, features an artificial reef structure that provides a clear focus for beginner divers. The site maintains an average depth of 12 metres, with the reef extending to 30 metres. Shore entry is available with on-site parking. Divers frequently encounter harbour seals, ochre sea stars, and rock crabs. Other species recorded include hermissenda, Monterey dorids, and various jellyfish. Visibility ranges from 3 to 10 metres, and currents are generally mild. Due to water temperatures between 8 and 12 degrees Celsius, thick thermal protection is essential. Divers must remain vigilant for boat traffic at the surface and potential entanglement hazards.

Graham's Wall is a challenging wall and reef site located in Victoria, Canada. The topography drops from 9 to 40 metres, with an average depth of 25 metres. Divers must contend with strong currents, making it essential to plan dives around slack tide. Visibility typically ranges from 15 to 30 metres. Water temperatures remain cold year-round, between 8 and 11 degrees Celsius, requiring appropriate thermal protection. Access is via a shore entry with on-site parking available. Due to the depth, current, and cold water conditions, this site is suited for intermediate divers with solid buoyancy control. A surface marker buoy is recommended for all dives.

Imrie Island, located off the coast of Victoria, Canada, features a shallow reef and kelp forest environment. Divers can explore depths ranging from 3 to 10 metres, with visibility typically between 5 and 10 metres. The site is accessible only by boat, and due to water temperatures consistently between 8 and 12 degrees Celsius, a drysuit is strongly recommended. The area is suitable for beginners building cold-water experience, though divers must remain aware of potential entanglement risks within the kelp. Proper buoyancy control is essential to navigate the reef structure safely while avoiding surf and entanglement hazards near the surface.

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.
