I would do 60/40. With climate change, you never know. Look at Texas where the utility operators decided not to winterize their power plant.
After looking the minimum temperature recorded in Toronto:
The coldest minimum temperature of −33 °C (−27.4 °F) was recorded on January 10, 1859.
You are OK with 50/50
