yea theres lots to see in the tdot. queen street is cool, as mentioned. just west of spadina and dundas is the Kensington Market area, which is a lot of small eccentric shops and vintage clothing if ur into that kind of thing, and a good bar/ clubbing/ entertainment area is adelaide and king. greektown on the danforth is pretty cool, and you can even go skiing in the city at earl bales park which has two small slopes and a chair. and yes louis is the correct choice of ski hill, best park in southern ontario since Blue went downhill. but toronto is too big and spread out to discover on your own as a tourist, hope whoever ur stayin with knows enough to show you around
