You gave very little information on how it happened. It is impossible to give you advice without knowing how it happened:
1) did you try to change or top up the coolant by yourself while the engine coolant is hot?
2) did you go to Canadian Tire to change the coolant that later leaked?
3) did you break any seals or losen the cap of the coolant?
etc etc. Please describe how it happened and what you did (if any) on the car before it occurred.
