Cant' get these at Cabela's, but you have time to order online/
I've always done well with these. Heavy for size and work well casting from shore or trolling.

I like the Spring Frog in green or orange.

I agree with Old Salt's recommendations.  I would add this, though: not only can the hot color or lure vary on a day-to-day basis, the preferred lures AND colors can vary on a lake-to-lake basis.  Forage foods available to lake trout can vary by lake.  My tried-and-true lures that imitate those forage foods may work well in the park's northwestern lakes but not produce as effectively further east.  And vice-versa.

My primary lake trout lure-types are:
  *  Lightweight "fluttering" spoons worked in conjunction with 1/2 oz up to 2 oz weights (depending on depth fish are feeding) affixed 4-5 feet up the line.
  *  Fat-lipped, wobbling deep-divers (I prefer white OR blue & silver).

OS is right about "experimentation," especially as you learn new trout waters.  If you put the lure-types mentioned in this thread into your tackle box, you'll at least have what you need to begin experimenting on a day-to-day and lake-to-lake basis.

Also, a decent canoe-type depth-finder can help you with your lure selection.  My experience is that "feeding" lake trout will come up a long way to grab your lure.  It helps to know HOW deep they are, however, so you get place your bait in the general ballpark just above them.  When they are REALLY deep, I find myself clipping on those 2+oz weights and using Sutton fluttering spoons more often than not.  Nevertheless, I have been amazed to have LT's occasionally come up from summer-time depths to nab lures that can't be running much deeper than 15 feet.

Anyway, that's my two cents' worth added to OS's dollar.

Craig Zarley who was a presenter at Canoecopia thinks all you need is a jig between 1/4 ounce and 3/4 ounce with a white twister tail.  You vertical jig the jig unless it is spring and the water is cold then you could fish in the conventional way with a jig.
Water temperature is more important than depth.  There is, of course, a correlation between temperature and depth.  I use a thermometer which records the temperature every 5 feet.  A depth finder is also very helpful.  My understanding is that trout will come up to get a lure, but rarely go down to get a lure.  Trout like water around 50 degrees.

Curious, jigging for Lakers other than spring sounds like you would need a fish finder.  I won't have that option.  I plan on trolling a 20 ft tail dancer first, and switch to a 30 ft if I'm not getting bit.

Since you don't have a fish finder and people have posted about using jigs/twister tail, maybe you could do something like this?

You can't have more than 4 hooks on a single line in Ontario except in certain instances/places.

If you could handle the extra drag, I don't know ( assuming it IS legal) why  you couldn't adapt this to different stick baits/jigs or maybe even combo of the two? 

Allows you to cover more water as you paddle. Start hitting fish at one depth, change over to single lure.
