Best way to invest 100k inheritance?

My dad passed away and left me $100 000 CAD and I'm not too sure what to do with it. I just turned 19 and my mom doesn't really know much about investing and finance in general. I have been researching a lot trying to figure out what to do with it. I'm going into 2nd year of university this September and I already have money put aside for tuition. I'd really appreciate any help! Thank you
