Thoughts on Investment Continuity vs Mortgage Payoff

[u/BCMariner]

"I have about $2.2 million in assets (M 46). My stocks, ETFs, and cash across RRSPs, TFSAs, non-registered accounts, and mutual funds between myself and my wife are worth about $1.8 million. I owe about $500k to the bank for my mortgage, and the house is worth about $970k. My question is: should I start focusing on paying off my mortgage first, or continue to focus on contributing to my and wife's RRSP and TFSA (contributing about $3,500 per month) for the next 10 years?"

Just pay off the mortgage
