Canadian fixed mortgage rates are rising due to higher five-year Government of Canada bond yields, influenced by global bond market turmoil and U.S. Treasury yield increases. Inflation risks, geopolitical tensions, and growing government debt contribute to this trend. Fixed rates have increased by 10-20 basis points, while variable rates remain stable. Borrowers with financial flexibility may prefer variable rates, but fixed rates below 4.19% are recommended amid potential future rate hikes.
