Since Covid has determined that Canada Post will no longer accept signatures, there is no sure way to make sure that the package is not just 'porch dropped'. There is no where to check a Do Not Safe Drop option when completing the order.
I do the sig option because on average the items I make and sell are in the $650-$1000 + range. I had one box go 'missing' one time and since then not an issue with the sig. I had one customer try to do a paypal scam on me, saying he never got his parcel, but I showed him the sig and asked who signed for it then? His tune changed to " oh sorry, I meant another company".
So TDLR: Make an option for the shopify Canada Post shipping page so we can click a Do Not Safe Drop Option.. which is free anyway, just provide a box to tick, so it prints on the labels.
