which canadian premed program is the best

Hi. My name is Sara and I have applied for different premed undergraduate programs in Canada. Currently, I have an offer from U of T Life Sciences with 100.00$ scholarship, UBC science, Western Medical Sciences, and SFU. I'm having a really hard time choosing between them. I have a great offer from U of T but I have heard that is a pretty difficult program and since GPA is very important for studying medicine or dentistry in US or Canada in the future, I am not sure if it is worth it. I am waiting to see if I get a scholarship from UBC. Can you tell me if there is a difference between the level of difficulty of these universities and could you tell me which one could be the better option for studying medicine or dentistry in the US or Canada in the future?
