My friend already identified it as belonging to the Heteroptera order, but I was wondering if anyone knows the name of the species.

Found in Toronto, Ontario, Canada, on July 21 2017, in a residential bathroom.

This is, indeed, a Heteroptera bug.

Luckily, this is not a kissing bug (which could be infected with Trypanosoma), but just an assassin bug, from the Species Reduvius personatus. Its common name is masked hunter.

Here is an image of the same bug, also in Ontario, from the Canada Pest Control website:

And in this photo you can see the long rostrum, just like in your second photo:

Finally, to see an assassin bug in action (a different species, though), have a look at this video from the Smithsonian Channel: https://youtu.be/hXFRAmWiaa4
