There's no doubt Rachel McAdams is Canada's sweetheart and she enchanted fans at the 2015 Toronto International Film Festival Monday evening.

The gorgeous Canadian actress stars in, "Spotlight," co-starring Mark Ruffalo and directed by Tom McCarthy. From the moment the 36-year-old arrived on the red carpet, you knew her ultra sheer gown was iconic Valentino. The beautiful dress sported a delicate floral embroidery and T-shirt style sleeves. The frock leaves little to the imagination, showing off her high-waisted bottoms and bra.

The "Mean Girls" star kept her makeup look simple, rocking a pink lip and a side-parted bun.

Earlier this week, McAdams attended two other TIFF affairs. First was the premier of her film, "Every Thing Will Be Fine," where she took her look to the dark side, wearing a sultry black strapless and mesh Cushnie et Ochs dress from the fall 2015 collection and Christian Louboutin 'Toerless Muse' T-strapped pumps. Rachel completed the vampy look with a standout burgundy lip.

Next up was a photo call for Jason Reitman's live read of "The Princess Bride" where she looked angelic in a white bohemian Zimmerman dress with the most elegant embroidery. She kept her beauty look natural, sporting a nude lip and highlighted eye.
