Where 1 "Canadian standard drink" is 1 bottle of beer, 1 glass of wine or 1 shot of liquor.

That shot size is 43ml so 5 shots totals 215ml of 40% spirits. In the UK a single is 25ml so it's equivalent of 8.6 'singles' / 4.3 'doubles'.

Didn't see the unit, sorry.

So, 1 standard drink = 1 bottle of beer = 1 reasonable glass of wine = 2 shots of liquor.
