If you don't mind a bit of 'back-of-the-envelop' calculations...

Let's start with the assumption that your burger costs $5 (this is in-line with the cost of, for example, a Big Mac).  Let's lump 50 cents off that for profit that will remain consistent.  So the input cost of our burger is $4.50 right now.

Labour costs currently work out to roughly 29% of input costs in fast food, so approximately $1.31 of your $5 hamburger goes to pay wages.  Wages are going up by up to 32%, but a fairly conservative guess is that total labour costs in a fast food establishment will rise, on average, by about 20% or 25%.  That would bump the labour component of our burger up to $1.57 or $1.63 respectively.

So a rough guess is that your hamburger cost might go up by 26 to 32 cents to cover the minimum wage hike.

The other labour rule changes are harder to put a dollar figure on, but they might add another 5 or 10 cents to the price, so maybe 31 to 42 cents?

... plus add 13% HST to that.
