Awesome articles. I have few questions. My situation is same like your example.
Our household income is approximately  $140,000  (I work full time and wife works part time). We put the minimum 5-per-cent down payment on a $405,000 semidetached house in Whitby , Ontario. Our mortgage is approximately $920 biweekly and it add up to approximately $2,700 on mortgage payments, taxes, utilities and maintenance. I bought this place in 2015 December and we are new to Canada, just over 2 years and 4 months now.
I have some USD funds and some Canadian savings now (Approximately $40000), planing to invest in RESP and some other accounts soon and $10000 towards yearly mortgage anniversary payment.. Our last year mortgage statement shows we paid almost $13000 to the Interest and $10000 to the Principal i believe or the other way round. 
So in your opinion, should we sell the house and rent it out for another 5-7 years or should i hold onto my property and finsih off the mortgage as fast as possible
