An important factor in a successful trip, be it solo or otherwise is planning wisely.  Understanding the environment you'll be in, as well as the requirements on you, both physically and mentally will ensure you'll be able to tackle any hurdles in stride.  It's wise to contact the locally ministry of natural resources to inquire about the route you propose.  Maps aren't updated every year and obstructions such as log jams are constantly moving.  It's also important to let family members know exactly where you'll be and your proposed route. 2 copies of a detailed float plan should always be filled out.  One left with a family member or friend, and one in the glove compartment of your car or with local authorities in the area you plan to travel. 

• Health:  Consult your physician before heading out in the wilderness alone.  Good health is important as your trip will involve lots of physical work.  Know the basics of wilderness first aid and carry a well equipped first aid kit.  You can view our recommended first aid kit here (PDF).
   

• Food:  Never run out of food.  People plan they're menus differently and we all eat different portions, but you should always have a surplus of food left over at the end of a trip.  It's like buying insurance.  You never know what can happen out there.  If you are stranded or laid up due to an injury, your situation will only be compounded if you are hungry.  As a general rule, bank on an extra 1 days worth of  food for every 7 days you're out.  You can view a list of recommended food here (PDF)
   

• Equipment:  It's amazing how many people we meet on the river that just didn't bring the correct gear for the trip they chose.  Sometimes it's a small item that makes life only a little uncomfortable.  Other times an important piece of gear is left behind, and it can ruin a trip in a hurry.  Make good lists and double or even triple check the items.  It can be easy to get out of hand and want to bring everything, but remember, it's only you carrying it.  Be thorough, but don't bring items that can serve double duty (like a headlamp and a flashlight).  We've comprised a extremely thorough equipment list.  These items won't be suitable for everyone or every trip so you'll have to pick and choose.  Still it's a good reflection of what you can reasonably expect to bring.  View our equipment list here (PDF)
   

• Maps / Charts:  Obtain all maps/charts/section sheets of the area you'll be traveling in.  Study them and know exactly what you're getting yourself into (portages, rapids etc).  If you study your router properly there should be very little surprises to deal with
   

• Clothing:  Another area of constant debate.  Many believe in bringing just the essentials, while others carry their closet, portage after portage.  One thing is true; in Canada's north, weather can be unpredictable.  Temperature swings of 20 degrees Celsius can occur within only a few hours, as can driving rain, lightning, wind etc.  The point is to be prepared, but reasonable.  There's no need to bring a winter parka on a summer trip because you think it might get cold.  Layering is the best option, allowing you to add or subtract layers as you see fit.  You'll be able to quickly adjust to changing conditions without overheating or getting cold.
