Does that matter in Ontario? Court decision in BC have established that if any heir disputes a will then the courts will do an even split taking into consideration gifts given to heirs before death.

OTOH some of my siblings had to change the locks on our mother's home, and started sleeping over in rotation, after our pot head brother living in her basement at age 60 had to be evicted for elder abuse, and for using her ATM card to raid her reverse mortgage. 

He had somehow talked her into making him the sole heir to whatever home equity was left if she died. It got scary when his new live in girlfriend punched our mother. 

I told them I was not interested in the house, hoping that the equity lasts just long enough to supplement mom's other income while she is alive. If she dies and pot head tries to take it all then I will be happy to be the bad guy who disputes, that and will redistribute my share among my other siblings who need it more than me.
