You want to be a competitive candidate to have a shot a med schooo, which means at a minimum having a top GPA and doing ECs and volunteering that demonstrate CanMED competencies. Hen you have the MCAT, CaSPER, the MMI, etc.
It you think that taking an Honours Program or doing research and even starting research before entry to undergrad, the more power to you. What you do not want to do is bite off more than you can chew and become a casualty of the process. And much more is involved. You need stress and time management skills and finding a s.o. who is needy for your energy and time can derail your goals and ambitions.
For undergrad, I selected a specialty program with internships in Exercise Science or Kin. I could have floated through the program with a B average, but then, I would have obtained a job at WalMart instead of entering into medical school. I needed to be a straight A student to be competitive. So, what I did was to choose what I considered easy electives to balance the more difficult core courses in my program. My s.o. was entirely supportive of my goals and we only saw each other Saturday nights for a few hours with no texting or other communication during the week. The material was not difficult but was voluminous. As a result to attain As, I studies to the point of exhaustion and I was totally wiped out at the end of each semester. I loved my program and with the internships, I was able to apply my theoretical knowledge with with elderly chronically ill patients, which was an excellent prep for medicine. I tired to find electives where the exams were multiple choice based upon the text of the course, which enabled me to entirely skip lectures and to use my time efficiently. I remember that for one course, I attended the lecture once and the prof called me out and made fun of me for not attending. Well, I led the course with my efficient strategy.
Take a program that interests you as you will likely do better. A difficult Honours program is not going to enhance your chances of being selected when he time comes. One of the most important factors in gaining entry is pure luck. Excellent candidates are routinely rejected every cycle.
