Hi! We're just north of Victoria, and lived there for years!
We went on a crusade last fall to bring our hydro bills down below the rate rider of about 1300kwhrs/60 days in our electric-everything house. It took a lot of effort (none of which feels like effort now that we're used to it), but we're down to daily use of about your range: 15-20kwhrs/day. That's in an 1800 sq ft house, though, with an electric well and septic pump. :)
I would go to Canadian Tire or some such and pick up a meter (sometimes called kill-a-watt's, but that's not what ours is). You plug your appliance into the meter, and plug that into the outlet, and it tells you what the power draw is. The biggest sucks are usually heat, hot water (laundry, showers, dishwasher), clothes dryers, older fridges, older freezers...but those don't seem like the likely culprits in your case.
Working from home will make your draw higher that your neighbors. You should be able to check the power draw from your laptops in the specs. But remember that sometimes lighting, etc just add up. Even a 13 watt CFL light, if it's on for 10 hours a day is going to make a dent. We can also tell when we've baked something in the oven for a few hours, so there are habits like cooking at home that can bring your usage up compared to neighbours eating out or just microwaving ready-meals. Trade-offs!
You don't mention laundry habits--do you use hot water to wash clothes or the clothes dryer? Those are big draws. But my money is on your tv. Plasmas are a huge energy suck...ever notice the heat that comes off them? From a quick google search, could draw as much as 500w in 2 hrs!
You should be able to log into your hydro account online and see your usage (no risk of the mislabeling!), including what the draw is throughout the day. That might be useful to identify particular appliances or leaks. We have fun looking to see what happens when we're home, away for the weekend, have houseguests, etc. We are geeks. :)
Good luck!
My husband would also remind you that at .07/kwh, the difference between say 10kwhrs a day and 15 is... 35 cents. But he's not as mustachian as me. :)
