Emil, not sure what insulation you have in the basement currently but if you look into the Eco Energy program, there are some good grants for insulation. You would pay around $325 for the home energy assessment and any improvements you do you get money back based on the improvement. There are very good rebates available for insulation, especially basements, so you will come out ahead if there is not much insulation there now.
