med student interested in summer job

I'm a 1st year undergraduate med student in the UK at a top 3 med school. I had a tough time deciding between medicine and business but i chose medicine. This summer i'm doing neurology research (will be using excel) but i'm also interested in doing some sort of summer internship at a bank or firm for next year. I'm really into news/current events, and i've always been really into data collection, sorting and analyzing. If its of any use i'm a Canadian citizen from Toronto. First is this even possible? Second is there anything that would suit me?
