Minesing Paddle Safety​

Know yo​​ur limit

Minesing Wetlands is not suitable for those who have little to no paddling experience. If you are a skillful paddler, but do not know your way around Minesing Wetlands, we recommend going with an experienced guide. There are unmarked routes, many unexpected portages, log jams, poison ivy, stinging nettle, and rapidly changing conditions making the trip potentially an unpleasant or even dangerous experience for those who don’t know how to navigate the wetlands. It is your responsibility to be prepared for the unexpected.

Organizations such as the Barrie Canoe and Kayak Club and the Friends of the Minesing Wetlands lead paddle trips into the wetlands using guides who know Minesing Wetlands well. There are other local tour guides who will also provide this service.


Under high flow conditions, the rivers can flood over their banks, creating conditions where paddlers can easily stray from the main channel and become lost within adjacent swamp forests and marshes.

Flooding over the banks typically occurs during the late winter/spring, but also after major storm events at any time of year. Minesing Wetlands requires paddlers to have strong experience with GPS/compass navigation and significant regard for weather conditions.

Small log jams or downed trees on all routes may be present.

Paddling the Minesing Wetlands?

Log jams are regular occurances when paddling in the Minesing Wetlands.

​Summer low flow conditions may create sandbars within the creek channel downstream from the George Johnston access point. Paddlers may have to exit their watercrafts to pull over the sand bars.

The location of the Willow Creek channel may shift from year to year. Paddlers must have navigation experience as ‘dead end creeks’ will be created, requiring paddlers to backtrack to the proper channel.

Moderate to high winds will make travel through the open marsh difficult.

In all but the highest water conditions, some sections along the Nottawasaga River have large, moving log jams and are not passable by canoe or kayak. River banks support tall summer vegetation including wood and stinging nettles and poison ivy and are notoriously slippery and difficult to ascend.

Although the main log jams are relatively stationary, they do shift slightly from year to year.  Log jams are a natural part of river wetland ecosystems and will be a consistent presence in the river.

Minesing - stinging nettle

Stinging nettle is found along the river banks of the Nottawasaga River. The stinging hairs on the stem, leaves, and flowers produce a painful sting.

​Downed trees, branches and associated log jams are prevalent along the Mad River route and require circumvention under all flow conditions via a variety of portaging, pull arounds and/or movement into flooded areas.  This route is recommended only for experienced paddlers with strong experience with GPS/compass navigation (and strong sense of adventure).​

Rescues in Minesing Wetlands

When visiting Minesing Wetlands, it​​ is your responsibility to make sure you are prepared.  Every year, first responders, including the Ontario Provincial Police, rescue unprepared visitors from Minesing Wetlands. 

These rescues can be complex, expensive, and time consuming.  First responders are putting themselves at risk every time they attempt a rescue in Minesing Wetlands. 

Paddlers need to be aware that they may be responsible for paying the cost of their rescue.

Many people get lost in the Willow Creek Marsh as it becomes lake-like and you can lose the creek channel.  

Changing Conditions

Changing weather, particularly in the spring and fall, can turn a glorious day into a cold and wet experience very quickly. Make sure you check the weather forecast before you head out. Bring a full change of clothes in a dry bag and dress for the weather. 

Calm, well-defined channels can suddenly become an open lake with white caps depending on the amount of rain or snowmelt in the watershed. Water levels can also get so low that paddlers are not able to pass through. This ever-changing landscape makes navigation a challenge.

In the spring, rivers and streams are fast-flowing and cold. There is a significant risk of hypothermia if you fall in. Check the flood conditions before you head out. And remember, there is always another day to go out – if the conditions aren’t right, play it safe and stay home.​

Paddling Saf​​ety

When heading out into Minesing Wetlands, follow good boating safety practices.

You need a sturdy, hard-bottomed boat to head in to Minesing Wetlands.  Canoes and kayaks are usually good options. Do not head out into Minesing on a stand-up paddle board or in a blow-up, inflatable boat. Submerged trees and logs may puncture inflatable crafts.

Ensure you have the mandatory marine safety equipment required by Transport Canada.

You should consider carrying additional safety items, including, but not limited to:

  • spare clothing in a waterproof bag (weather can change without notice, and it’s best to be prepared);
  • compass and navigation system (GPS), map and knowledge on how to use them;
  • drinking water and snacks; and
  • a first aid kit.

Recognize the signs and symptoms of hypothermia.

A successful, safe trip begins with good p​reparation. Before you leave, run through a pre-departure checklist and be sure to tell others where you are going and what time you expect to return. ​
