(CNN)Waves of asylum seekers continue to cross into Canada from the United States, drawing concerns that the numbers will only rise as the weather gets warmer.

Over the last year, Canada has seen what has been called an “unprecedented” surge of asylum seekers, with more than 25,000 people intercepted by the Royal Canadian Mounted Police as they crossed from the US since January 2017 to March 2018.

And this year, the rate appears to be growing.

The number of people intercepted in the first three months of 2018 more than doubled those in the same time period last year. And in 2017, the number of people intercepted at the border escalated in the summer.
