Yeah Quo has REALLY good brushes, especially for the price. And they go on sale a lot (up to 40% off sometimes), which is quite good, because you can get really nice basic brushes for a really great price. Of course they're not MAC-quality brushes, but for stuff like blush brushes, sharpeners, crease brushes, etc., it's amazing what you get for the amount you pay.
Lise Watier is a great brand too! The glitter liquid liners are GORGEOUS and they have tons of shades to choose from.
And I don't think that GOSH is Canadian (it's Danish, I believe), but GOSH is only available at Shoppers. And GOSH is actually SUCH a great brand. Their Velvet eyeliners are waterproof and come in so many colours. And it doesn't smudge or budge or fade throughout the day. Their liquid liners are similar to MAC Liquidlast, and they come in all the colours of the rainbow.
And just so you all know, Quo, Lise Watier and GOSH are all available at Shoppers (with Quo being Shopper Drug Mart's cosmetic line).
