MONTREAL -- A day after Montreal Mayor Valerie Plante announced that she had potentially been exposed to COVID-19 and would self-isolate, she says she has the all-clear.

Plante said in a live radio interview on CJAD on Wednesday afternoon that she will end her self-isolation after those who had potentially exposed her to the virus tested negative.

On Tuesday, Plante, along with several Montreal-area mayors and three provincial ministers, went into voluntary self-isolation after Longueuil's mayor tested positive for COVID-19.

Longueuil Mayor Sylvie Parent said she will remain in isolation for 10 days following her announcement, after receiving a positive test on Sunday.

Plante had said on Twitter that she was awaiting the test results of Minister Chantal Rouleau, the official who she had been in close contact with, who had in turn had her own potential exposure to the virus.

On Wednesday, Rouleau wrote on Twitter that her test had come back negative.

Correction:

A previous version of this story reported that Mayor Plante had herself gotten a negative test result. In fact, she made her decision based on others' test results. CTV regrets the error.
