There are a couple details which don't make a lot of sense. Their TFSAs are doing very well to be worth the values given. Is it possible that they are combined with RESPs which would have been logical given their daughters ages?
I also find the monthly pension figure given after what would be 35 years of service seems very modest. The $2,060 per month would leave a very big hole to fill from their other sources given their desire to have $70,000 after-tax in retirement.
