Undergrad major to be a medical lab technologist in Canada

Hi everyone, I’m sorry if this is the wrong place to ask but I was wondering about what I should major in if I want to be a technologist. It’s to my understanding that to be a technologist rather than a technician, at least 2 years of undergrad are required (in Canada).

I was thinking of either a BSc in Microbiology & Immunology or a BSc in Physiology. Which would be more useful for the 2 year program I’ll take afterwards to be a technologist?

Thank you for reading and I appreciate any advice!
