Bull Bitcoin is the best way to send BTC and have it automatically converted to fiat. I think you’ll need a Bull account and I don’t know if you need to be Canadian to have one (nostr:npub1t289s8ck5qfwynf2vsq49t2kypvvkpj7rhegayrur0ag9s2sezaqgunkzs). You’ll need your recipients email address that is tied to Interac e-transfer at their bank. But once you have that you can send BTC to their email through Bull. https://www.bullbitcoin.com/payments
