1,000 Islands


Dive the Canadian Caribbean
Join us on our East Coast Dive Tour trip to the 1,000 Islands to dive the incredible wrecks of the St. Lawrence River. Visibility in these 70°+ waters can reach 60 feet this time of year, and the currents cause the lake to have no thermoclines – even to depths of 130ft – earning the name Canadian Caribbean. This trip is perfectly suited for all levels of divers.

The 1,000 Islands are as beautiful underwater as they are above water. The irregular bottom contour provides many shallow shoals that surprised unsuspecting ships, leaving them scattered about the lake bottom, but remain in excellent condition due to the freshwater. From paddlewheel steamers of the 1800’s to contemporary freighters, this river has them all awaiting us.

Celebrating 20 years!
2019 marks 20 years since our first trip to Canada, which started back in the Fall of 1999.  7 of us drove up and dove Saturday and Sunday.  Since then we've made regular trips to the St. Lawrence River and Lake Ontario.

Sailing on the best of the river …
We’ll be diving off some of the most spacious boats available featuring enclosed cabins, wide, easy to board ladders, an indoor head and an upper deck for relaxing between dives.


During this trip, you’ll have the opportunity of diving some of the best and most unique wrecks in the area. These wreck sites include:

Robert A. Gaskin
The Gaskin was a double masted iron rigged wood barge built in Kingston Ontario in 1863. She is 113' x 26' and sits on a firm bottom with the bow at about 50' and the stern at 65'-70'. The Gaskin's upper deck is quite open allowing ample ambient light for easy penetration throughout the wreck.  A great wreck for new wreck divers!
  See more spectacular photos of the Gaskin.

Double tanks, drysuits and DPV's are not required to dive these wrecks.

Lillie Parsons
The Lillie Parsons is a unique center-board schooner that's 131 feet long.  On August 5th, 1877, while carrying a cargo of coal, she hit a rock and took on water as her cargo shifted during a squall. She sank next to Sparrow Island in only 40-60 feet of water.  A great dive with even greater drift!
  See more spectacular photos of the Lilly Parsons.

   Double tanks, drysuits and DPV's are not required to dive these wrecks.

The Kingshorn is a largely intact wooden barge sitting upright in 90' of water. Divers love this wreck for it's great photo opportunities below deck and around the ships wheel.
  See more spectacular photos of the Kingshorn here.

The area's most popular wreck, the Keystorm was a 256' steel laker built in 1908 that went down in October, 1912 after it struck Scow Island's outer shoal. From swimming through it’s immense cargo holds, to the spectacular photo opportunities by the wheelhouse and prop, this wreck has something for everyone. She sits on its starboard side in 20' to 120' and is truly an unforgettable wreck.

  Double tanks, drysuits and DPV's are not required to dive these wrecks.

 This 4-legged ship was used to dynamite sections of the St. Lawrence Seaway to make it deeper and safer for travel. She awaits us, upside-down in 80 feet of water outside the shipping channel.
  See more spectacular photos of the America and here.

Our Monday, our Advanced dives will be on the wreck of the:

Eastcliffe Hall
This contemporary 343' steel freighter sank in 1970 after hitting a shoal while carrying a cargo of pig iron. Although much of the superstructure was dynamited to eliminate a navigational hazard, most of the wreck is intact below the hull while the cargo holds have lots to explore.
  See more spectacular photos of the Eastcliffe Hall.

And during our surface intervals on Saturday and Sunday we’ll be BBQing Hot Dogs and Burgers for your dining pleasure.

We’ll be spending Friday through Sunday nights at the Brockville Comfort Inn located right off Route 401 in the center of Brockville. The Inn is located near all the area restaurants and features a Complimentary Continental Breakfast and free nightly popcorn.

Other activities…
We'll be doing morning charters which will bring us back to the dock early afternoon to allow plenty of time for sightseeing, shopping, tours and spending time with the non-divers who may have joined us on the trip.

Non-divers can take a City of the 1,000 Islands Cruise or visit the historic Boldt and Singer Castles.  There is the ever popular Brockville Rib Fest all weekend and the Poker Run on Saturday.  Plus there is a Dairy Queen minutes from our hotel.  There are lots of lighthouses to visit, or hit the mall in Brockville for some great deals due to the value of the American dollar in Canada.

Plus, new in 2017 is Skywood Eco Adventure.  Only 10 minutes from DiveTech, this new outdoor area includes a Zipline Tour, Arial Adventure Courses and a Treewalk Village.
