Take Note if You Plant Trees Near One of These Rainy Regions
Canada is home to a variety of climate and weather patterns – and these can affect how you take care of your trees.
Canadians living in rainy areas should take special note of the weather forecast. Rainfall can affect the health of the trees in your yard – especially when you face extreme weather conditions like rain pouring down.
Which cities in most thunderstorms in Canada have the most rainfall, and what steps should you take to protect your trees during heavy storms? Read below to find out.
The Link Between Heavy Rainfall and Tree Growth
A regular amount of rainfall is healthy for trees that are actively growing. Roots need to send water throughout the tree for it to sustain healthy growth patterns – and rain is a great source of water!
What about heavy rainfall, though?
Trees can become severely damaged from too much water. It’s true that tree roots need water, but they also need oxygen in order to keep the tree healthy. While it’s hard for trees to get oxygen, fortunately, the soil has pores to help oxygen flow through.
When trees get too much rain, though, the pores fill up with water and become clogged. As a result, the tree is unable to collect oxygen and transport it throughout the tree – ultimately leading to disease and rot.

2025 Update: Shifting Weather Patterns in Canada’s Stormiest Cities
How Recent Changes in Rainfall Trends Impact Your Trees
Canada’s weather continues to evolve, and in 2025, we’re seeing substantial shifts in storm activity across many cities. Climate changes and shifting weather systems are causing more frequent, intense, and unpredictable rain event, that may seriously have an effect on the health and stability of trees in urban and rural landscapes.
Below, we take a deeper look into how stormy climate in 2025 is shaping up and what proactive steps you should consider to keep your trees secure and strong.
Halifax, Nova Scotia
Halifax remains one in every of Canada’s stormiest cities – but 2025 has added longer-lasting storms and more days with consecutive rainfall. These conditions have left soil waterlogged for extended periods, which puts stress on tree root systems.
What to Watch: Signs of root rot, leaning trees, or leaf yellowing.
Tree Tip: Consider soil aeration or installing in drainage solution near trees prone to pooling water.
Saint John, New Brunswick
This year’s storm season arrived early, with extreme rainfall already determined in past due February. The saturated ground from back-to-back spring storms is leading to greater tree instability, especially for younger or newly planted trees.
Tree Tip: Use tree staking strategies to help younger trees and add extra mulch to regular root temperature and moisture.
Vancouver, British Columbia
2025 has shown a trend toward short-period, high-intensity rainfall event in Vancouver. While total rain days are similar, the sheer volume all through every storm has increased. This can cause surprising erosion around root bases and flooding in poorly drained yards.
Tree Tip: Inspect slopes and planting beds. You may need to build retaining structure or use deep-root watering strategies to inspire robust root systems.
St. John’s, Newfoundland
Newfoundland’s capital city is home to vibrant culture and comforting views – but it also has a fair share of storms. St. John’s faces about 11 days of stormy weather per year.
Abbotsford, British Columbia
About 140,000 people live in this B.C. city. With plenty of farmland and a metropolitan flair, there’s plenty to do in Abbotsford. Tree planters should be warned, though: the city faces about 11 days of stormy weather each year.
Quebec City, Quebec
Many call Quebec City home – and others call it a popular tourist destination. It has interesting architecture and a rich history – and, of course, stormy weather. Quebec City gets about 7 days of stormy weather per year.
Moncton, New Brunswick
This New Brunswick city was once a transportation hub – now, it’s a vibrant tourist destination and friendly home to many Canadians. Moncton faces almost 7 stormy days per year.
Trois-Rivieres, Quebec
Named after the nearby Saint Lawrence River and its three ‘mouths,’ this city is home to plenty of rainfall – it faces about 6 days of stormy weather throughout the year.
Windsor, Ontario
This Ontario city rests across from Detroit, Michigan. Windsor faces about 6 stormy days per year, so tree owners in the region should take warning.
London, Ontario
This southwestern Ontario city is home to more than 300,000 people. London faces about 5 days of stormy weather per year – narrowly beating out Kingston, Ontario, and Montreal, Quebec, to make the top ten.
Emerging Trends: New Areas Facing Storm Risk
Sudbury, Ontario
Sudbury is not traditionally one of Canada’s stormiest cities, but 2025 has introduced an unusual spike in hurricane days, especially in early spring. Rapid snowmelt followed via heavy rain has led to flooding and soft ground conditions.
Tree Tip: If you are in Northern Ontario, put together for extra unpredictable climate. Reinforce trees with help ties and schedule seasonal inspections with an arborist.
Charlottetown, PEI
Another region to watch in 2025 is Charlottetown, which has already confronted three principal storm events by April. With more Atlantic moisture being driven inland, cities like Charlottetown might be delivered to the stormiest list next year.
Tree Tip: Keep trees trimmed of deadwood and ensure they have room to sway safely in strong winds.
