Environment Canada has issued a yellow frost advisory for Burlington and the surrounding region as temperatures are expected to drop below freezing. The advisory warns that patchy frost could cause damage to sensitive plants, trees, and local crops.

According to the weather agency, residents in Burlington, Oakville, and across the Greater Toronto Area should prepare for chilly conditions. Temperatures are forecast to reach a low near freezing, with frost expected. Because this weather arrives during the first week of May, when many people have already begun their spring planting, the potential for garden damage is a concern.

Officials advise homeowners and gardeners to protect their plants from the cold. Recommended steps include covering plants with protective materials like plastic containers, sheets, or bags, particularly in areas known to be prone to frost.

This cold snap is part of a broader trend across Ontario this spring. A lingering weather pattern known as La Niña has contributed to a slower, cooler start to the season than what is typically expected for this time of year.
