Yup its true, McDonald's is to serve up some tasty WiFi access in the very near future. Now I'm sure your thinking that this is only for the states, but your wrong!!! According to this Globe and Mail article we will be able to use up to 45min of internet access with a >= 3$ purchase.
They say 10 locations will get WiFi by the end of the year, currently two are in Toronto, one in Scarborough and the 4th in Mississauga (the gawdy one in Millcreek Drive)
