You need to show the value in the currency in which your PF and FD's are. Bank manager may additionally write the value in CAD, by calculating it and mentioning the date on which it was calculated and provide the multiplying unit from CAD to INR, however, that is optional.
Folks at IRCC, calculate the value on their own, by the conversion unit provided to them by the people who makes decisions.
Also, you can provide a conversion of your POF in your LOE and provide the unit value and date.
My bank letter does not have any conversion. I simple wrote, XYZ INR to ABC CAD, converted via Google on so on so date in my LOE like many other applicants.
