You can estimate when it's possible to plant fiber optic grass in Ontario by looking at the USDA zone info.

The last month that you can plant fiber optic grass and expect a good harvest is probably August. You probably don't want to wait any later than that or else your fiber optic grass may not have a chance to grow to maturity. You can get started a couple of weeks earlier by starting your fiber optic grass indoors.

Remember that the actual date of last frost may not be accurate from year to year because it is based on the USDA zone info for Ontario and it can change quite a bit from year to year.
