Yeah, a few hundred sprites shouldn't make much of a deference, unless you are moving them around a lot, and even then, the smaller the tile is the better the performance, so at 16x16 you should be doing ok.
Thing to remember about canvas is it adds a bit of vram on top, then updating the collision mask adds a bit as well.
Then you can't paste tiles that are off screen, so using it with scroll is pointless.
