Twenty-one people crossed the border illegally overnight near a Manitoba community where there has been a surge in people seeking asylum.
RCMP say all of the people asked to make refugee claims and were taken to the Canada Border Services Agency port at Emerson so they could do so.
An increasing number of refugee claimants, mostly from African countries such as Somalia and Ghana, have been risking freezing temperatures and walking through fields to get over the border and into Emerson in the last few months.
Two men from Ghana were severely frostbitten in December when they crossed the border at Emerson.
