What Ontario areas are considered "local calls?" | 7-Eleven Rates and Plans | Consumer forum

I recently purchased the flip phone and so far am pleased with Speak Out
wireless. The information page states;

"SpeakOut Wireless offers a larger calling area than traditional Wireless service providers. In fact, many areas in your province are considered a local call. See the current SpeakOut Rates."

I clicked on the link to find out which areas in the province (ON) are considered
local calling areas, but the link didn't work.

What areas are considered local to my area of Oakville, ON?

Thank you ~
