Kitchener Fence by-law

That, and the odd package sizes of many food and drink products in Canada - Imperial measure packaging just quoted in metric rather than changing the package sizing to something tidy.

Cartons and tins are usually made to US sizes or made in the US so it makes sense that most aren't really rounded out to be metric, hence all the 473ml cans of beer and 1.89L juice cartons. Milk cartons seem to be 2L though and bags are 4L but the butter is all 454g. I suspect the butter was just because they didn't want to buy new moulds back in the day?

I suspect things will always be this way unless the USA does a wholesale conversion for some reason.
