We need some people from Toronto to take responsibility of this. If it will be in Niagra Falls, Summer is definitly the best time.
We need to select the date, make plan what we will do there.
Those from USA, all citizens can just come to Canada, no need for visa. Those with green card, may need a visa (Unsure- Someone needs to check).
A good choice for this can be May 21-22 (Victoria Day Weekend). All students will be free as exams will be over.
Anyways, someone needs to take responsibility to make it happen.
