Will two P/F grades be looked at negatively for T10 schools?

Hi everyone,

I'm in my final term of university at a top Canadian school (think Mcgill, University of Toronto, Waterloo) doing a double major in economics and statistics. I have secured a job in a T2 consulting firm in the U.S., but am planning to get an MBA at a T10 (or hopefully an M7) after a few years of working. My current GPA is 3.71, and the last time I took a P/F grade was for a French course in first year( during the Covid crisis in Spring 2020).

The problem is that while my first three years were pretty fine, with consistent A's or A- 's, my fourth year has been on a downward trajectory. In the first term of fourth year I got a B in two courses. Right now (second term), I am planning to P/F two courses, a physics course and a french course. If I keep these grades I expect to graduate with a 3.65, but if I P/F them I expect to graduate with a 3.72.  However I am worried that P/F ing these courses will be even worse of a look on my current downwards trajectory. 

Should I Pass/Fail these courses or just take the hit to my GPA?
