"can receive a pension of around 50%, sometimes reduced where there is an age difference of more than 10 years "
This is my situation exactly.My wife will receive 37.5% of my CPP,Canada pension as she is below 65. there are other assets as well. My biggest faer is her giving it away to her eldest sister who is a working poor gov't employee. Blood is thicker than water in LOS but I've had a dam'n good run here so who cares!
