How many volts do you get while the engine is running?

Your battery isn't producing enough current to crank the starter, it's either because you alternator isn't putting out enough to store a proper charge in your battery, or your battery has a bad cell.

If the battery is getting >13.5V while the engine is running, then the alternator putting out sufficient voltage to charge. Check your battery terminals for corrosion, check to see if you have any dry cells.

Making only short trips isn't really good for a battery, especially in a cold place like Thunder Bay. It doesn't get a chance to fully recover from the last start. A partially discharged battery makes it more prone to freezing -- and once it's frozen applying a charge to it can pooch it for good.
