How to call Canada from the United States in 2026

The dial string is +1 followed by the 10-digit Canadian number. Canada and the United States share the North American Numbering Plan, so there is no separate country code to learn, the area code carries the routing. Canadian 1-800 numbers still often fail when originated as a US domestic toll-free dial.

The dial string

To call Canada from the US:

• ›+1 {Canadian area code} {number}, or
• ›1 {Canadian area code} {number} from a US phone as a normal NANP call.

There is no leading zero to drop. A Toronto number (416) 555-0134 becomes +1 416 555 0134. A Vancouver number (604) 555-0177 becomes +1 604 555 0177. The international 00 prefix is irrelevant on this corridor when dialing from a US handset inside NANP; use + or 1.

Mobile vs landline

Canadian mobiles and landlines share 10-digit NANP formatting. Major area codes: Toronto 416/647/437, Montreal 514/438, Vancouver 604/778/236, Calgary 403/587, Edmonton 780/587, Ottawa 613/343, Winnipeg 204, Halifax 902. Number portability means the area code no longer reliably indicates wireless vs wireline.

Canada does not bill the receiver for ordinary incoming calls from the US.

What it costs

Four realistic routes for a US→Canada call in 2026:

• ›US mobile plan. Most US unlimited plans treat Canada as included or near-domestic (T-Mobile Magenta-family Canada talk; many AT&T and Verizon postpaid plans include Canada). Pay-as-you-go without Canada inclusion is still usually under $0.25/min, far cheaper than overseas corridors.
• ›Pre-paid international calling card. Rarely worth it on this corridor once Canada is bundled on the handset plan.
• ›VoIP app-to-phone. Google Voice and similar US VoIP products often terminate to Canadian numbers at a few cents per minute.
• ›Browser-to-phone via WorldDial. From $0.21/min on the public rates table, see call Canada.

If the US plan already includes Canada, the handset wins. Browser-to-phone is for Wi-Fi-only devices, foreign SIMs parked in the US, or callers whose plan still meters Canada.

Toll-free numbers from this corridor

Canadian 1-800/1-888/1-877 numbers are NANP toll-free. Some accept US originations; many government and bank lines still reject or misroute cross-border toll-free dials. When a toll-free fails, use the institution’s local geographic +1 number from the same contact page. Canadian numbering resources are maintained via CNAC.

Best calling windows

Most of Canada’s population sits in Eastern (UTC-5/−4) or Central (UTC-6/−5) time, aligned with US zones. Vancouver (Pacific) matches US Pacific.

Best window for CRA and bank helplines in Toronto/Ottawa: 09:30-11:30 local Eastern. Queues thicken after lunch local time as domestic callers return from midday. Avoid Canadian statutory holidays (Canada Day, Thanksgiving in October, Boxing Day) when contact centres run skeleton staff.

For Pacific Canada, shift three hours later than Eastern windows. A Toronto 10:00 call is 07:00 in Vancouver, too early for many west-coast offices even when Eastern Canada is already open.

Pitfalls specific to this corridor

• ›Assuming every +1 number is US-rated. Caribbean and Canadian destinations share +1; billing and hours differ. A number that “looks domestic” on a US phone can still be an international-rated Caribbean termination on some plans.
• ›Toll-free that worked last year. Canadian institutions rotate which 1-800 lines accept US origination after carrier changes. Keep the geographic fallback from the contact page in the same note as the toll-free string.
• ›10-digit dialing overlays. Cities with overlays require ten-digit dialing even locally; omitting the area code fails. Toronto, Montreal, and Vancouver overlays are the usual traps for older contacts saved as seven digits.
• ›CRA and bank identity scripts expect Canadian phone context. Have SIN/account data ready; some IVRs ask for a Canadian postal code early. US ZIP formats will not satisfy those prompts.
• ›Provincial holidays. Ontario and Quebec civic holidays do not always match US federal holidays. A call placed on a quiet US afternoon can still hit a closed Canadian provincial contact centre.

Quick checklist

• ›Dial +1 (or 1) plus the full 10-digit Canadian number.
• ›Confirm the area code is Canadian before assuming US-domestic billing.
• ›Keep a geographic fallback if 1-800 fails.
• ›Call during the destination province’s morning office hours.
• ›Use the handset when Canada talk is already bundled; otherwise a per-minute browser route is enough.
