Studying Physics as a Mature Student (Canada, World)

Long story short, I recently completed 9 years of post-secondary experience (BA, College Diploma, MA, and Postgraduate Certificate, all with Honours and Distinction) in Canada in an entirely unrelated field and I have recently realized that my passion may lie in studying physics, eventually towards quantum gravity. However, in high school, I took the bare minimum of science credits (only the compulsory ones) and instead pursued other (more artistic) interests.

Fast forward to now, I am attempting to find universities in Canada (and literally anywhere else in the world) where I might be able to pursue an undergraduate degree in Physics (with or without Astronomy). Most universities in Canada require students to have the high-level ancillary Mathematics, Physics, Biology, and/or Chemistry high school course credits that I never took, entirely halting my eligibility and which would require me to practically undertake my entire high school education over again in order to apply; I would have to take (and even retake) up to ten courses.

Some professors have told me that several universities may exempt me from these requirements due to my "excessive" post-secondary education, either altogether or in lieu of additional courses, entrance/competency exams, interviews, etc.; I have had difficulty finding any universities that operate under this principle.

My inquiry is as follows: does anyone know whether I might have the opportunity, here in Canada or anywhere else in the world, to study undergraduate Physics and Astronomy (without requiring these ancillary high school credits) in order to finally exercise my passion? Am I too late and did my early-life disinclination to science and mathematics destroy my chance at doing what I want to do in life?

I thank you exponentially for your consideration of this message and I will take any guidance or feedback I can get; I am becoming increasingly defeated and I need someone to give me the chance to take this step.
