`exchangeRates.get`

Get the Bank of Canada daily exchange rate for a day, as units of quote for one base (for example base USD, quote CAD, date 2026-09-25). Pairs without CAD are crossed through CAD; a weekend or holiday uses the closest earlier business day. Returns the rate, the day it was published for, the series and a source description to keep with a match or tax review. Reads bankofcanada.ca and never changes anything.
