Just a couple of words about the best time to consider scheduling a portrait now that it's finally warm and sunny in Toronto--halfway through August.
If you wish a portrait done inside the time of day doesn't matter much, but if you've got a location in mind that's outside, realize that the middle of the day is the worst time to shoot. Bright afternnon sun might seem like good photography weather but in fact it's not, the light is much too harsh and high that time of day, so if you'd like something outdoors early morning or late evening is best.
I'd especially recommend early morning since it's still reasonably cool at that time. Just something to consider....
