Exchange rate to use for Canadian Dollars (CAD) for Schedule FA?

Dear CA Club

I request you to guide me on following:

1. Which exchange rate should I use for CAD to INR conversion for Schedule FA? There is a SBI TTBR available on Github but it says to only use for RS. 10 - 20 lakhs. Should I use that or use something like Bank of Canada exchange rate?
2. If use SBI TTBR then which column should I use like "TT Buy" rate?

Thank you so much in advance
