Pedestrians and cyclists, be aware of where the sun is! Drivers may not be able to see you - especially in the first and last hour or so of daylight.

Air India Memorial Sundial Repaired in Time for 25th Anniversary Ceremonies
In early 2007 we had the privilege of designing the sundial feature for the Air India Flight 182 Memorial in Toronto. The sundial was unveiled by Prime Minister Stephen Harper on June 23, 2007, the 22nd anniversary of the bombing.
And on June 23, 2010, the Prime Minister was again on hand, this time for the 25th anniversary ceremony.
Five day later, on June 28, 2010, Indian Prime Minister Manmohan Singh visited the memorial and participated in a private remembrance with representative victims' family members.
Although the sundial had been vandalized in the Spring of 2010, repairs were made just in time for the 25th anniversary. For further information about the Air India Memorial Sundial see the following:

Peak UV Times
Our sunrise/sunset tables can be used to determine the time of peak UV radiation in your area. Simply look up the time of Solar Noon on our tables - this happens to coincide with peak UV time. Just remember to add one hour to our tables if Daylight Time is in effect.
Take precautions 2-1/2 hours either side of solar noon. For example, solar noon occurs in Toronto tomorrow at 1:25 p.m. EDT, therefore, the danger period runs from about 11:00 a.m. to 4:00 p.m.

For a free sun table for the current month in your location visit our Sun Tables page at http://www.sunposition.com/tables.html
Environment Canada states:
- "The amount of UV you receive depends on both the strength of the sun's rays (measured by the UV Index) and the amount of time you spend in the sun. Reduce your time in the sun – seek shade, particularly between 11:00 a.m. and 4:00 p.m. from April to September.
- Cover up, wear a broad-brimmed hat, a shirt with long sleeves and wrap-around sunglasses or ones with side shields
- Use sunscreen – with a sun protection factor (SPF) of 15 or higher, with both UVA and UVB protection. Apply generously before going outside, and reapply often, especially after swimming or exercise
- Listen for Environment Canada’s UV Index – it’s included in your local weather forecast whenever it is forecast to reach 3 (moderate) or more that day."
