Forensic Science University (trent vs laurentian vs uoit)

Hi, I'm graduating from highschool this year, and I'm interested in Forensic Science.
I have applied for Forensic Science at UOIT, Trent, and Laurentian.
As of now, I got accepted to UOIT and Trent for Forensic Science.
But I got accepted to Chemistry at Laurentian.
Some people said that I can transfer program once I get in Laurentian, but it's not guaranteed.
I'm not sure where to go, which university should I choose?
Can somebody plz help me? It's stressing me out D:
