National Bank is the smallest of the Big 6 but has aggressive Ontario growth ambitions, particularly after acquiring Canadian Western Bank in 2025. That means retention pricing is often more competitive at NBC than the older Big 5 — worth a call before you assume you have to switch.
How National Bank delivers your renewal offer
NBC mails the renewal 21–30 days before maturity and posts it in National Bank Online Banking under Accounts → Mortgage → Documents. Language is often bilingual (English/French).
National Bank All-In-One Banking
The National Bank All-In-One is unique among Canadian banks — it combines chequing, savings, mortgage and line of credit under a single account, with interest calculated daily on the net balance. It is registered as a collateral charge. Switching at renewal requires unwinding the entire structure, which typically costs $800–$1,200 in legal fees. If you don't actively use the All-In-One's cash-sweeping features, consider asking NBC to split it into a straight mortgage before renewal.
Negotiation questions that work at NBC
NBC's retention line is 1-888-483-5628. Effective language: 'What is your best rate today on a 5-year fixed for renewal?' NBC retention is often willing to match broker quotes in Ontario markets where NBC is trying to gain share.

Frequently asked
Is National Bank All-In-One worth keeping?
Only if you carry meaningful cash balances that offset the mortgage — the interest savings can be real. If you don't, the collateral registration is friction with no upside.
