We look forward to warmer weather and sunshine, but too much sun can cause problems. All skin colours are susceptible to the harms of ultraviolet rays. UV radiation can cause sunburn, premature aging, cataracts and over time, skin cancers. This is why it is important to protect your skin and your eyes.


The higher the UV Index, the stronger the sun's rays, and the greater the need to take sun safety precautions.  In Canada the UV Index ranges from 0 to 11+. When the UV index is 3 or higher, protect your skin as much as possible. In Canada, the UV index is most often 3 or higher from 11 AM – 3 PM, between April and September. Check the daily forecast for the UV Index UV Index forecast.


Wear sunglasses or prescription eyeglasses with UV-protective lenses.


Use sun screen SPF 30 or higher that is labelled “broad-spectrum” and “water-resistant” on all exposed skin. 

  • Apply generously. Re-apply periodically, especially after sweating or going in the water. Don’t forget often missed areas: tops of ears, nose, shoulders, feet, scalp (if exposed). SPF 30 sunscreen lip balm is also recommended to protect your lips.
