Found Walmart.ca has reduced 47 Lego items with most at 20% off to price match other retailers. Since the prices do not show as sale items on the actual product pages there is really no other way to post this.
In the stocktrack link, on the "price drops" panel on the far right, click the weekly tab, then type in lego as shown below. You'll see your options (product, price, and inventory) and can click through from there.
You'll likely find matching prices for these products on other retailers like Amazon.ca, so search those sites as well or google if you find a product you like and would rather purchase from elsewhere.
