Area Code 705 spans central and northern Ontario, from Barrie to North Bay to Sault Ste. Marie. Introduced in 1957, it’s a code rooted in cottage country, industry, and community pride. A call from 705 could come from a mining town, a lakeside resort, or a local mayor’s office. It speaks to Ontario’s vast interior,reliable, grounded, and deeply Canadian. Though joined by overlays like 249 and 683, 705 remains iconic. For many, it's more than a code,it's a sense of place.
