A complete international number is built from four parts. Here's the anatomy and the dialling order.
Number anatomy
Format follows ITU-T Recommendation E.164 the international public telecommunication numbering plan.
Press + on a mobile (hold the 0 key), or dial 00 from most countries / 011 from North America.
Dial +1. This identifies Canada on the global telephone network.
Type the first part of the local number. Drop the leading 0 if there is one.
The remaining digits route the call to the specific line in Ottawa or elsewhere.
To call Canada on WhatsApp, save the number with +1 and no exit prefix — WhatsApp dials from your contacts, not a dial pad. Voice and video calls are free over data.

TKOS provisions +1 DIDs and termination through direct carrier interconnects.
Whether you're reaching Canada for business or family, three habits keep every conversation crystal clear and a clean route from TKOS handles the rest.
Ottawa routes support G.722 wideband on North American carriers — an HD-compatible headset makes the gap between good and great audio obvious on these Zone 1 links.
Ottawa is ~15,698 km away — latency runs 280–310ms. Use wired ethernet to eliminate Wi-Fi jitter on this long-haul path.
Schedule Canada calls during Ottawa business hours — 09:00–17:00 America/Toronto — your contact will be at their desk in a quiet space rather than taking the call on the move.
