Keep a Canadian phone number active abroad.

Keep the number active, ask the new provider to manage the transfer, and confirm any local exchange or service-area constraint before cancelling.

Active service matters.

The CRTC advises arranging number retention with the new provider before cancellation. Geographic exchange constraints can apply, especially when moving between service types.

Long-term strategies

A low-cost Canadian wireless plan is generally the strongest anchor for important verification. Wi-Fi calling can reduce roaming dependence, but setup, device and country restrictions must be checked. VoIP may lower the cost for calls while reducing short-code compatibility.

Moving countries

Keep the Canadian number only for legacy accounts that still need it, and add a local carrier number for new-country services. This reduces the pressure on one number to satisfy two different markets.
