Marijuana producer Aphria Inc. says it met with the Toronto Stock Exchange last week to discuss the exchange's recent guidance that pot firms with U.S. exposure could face delisting.

Aphria chief executive Vic Neufeld says the company reiterated its commitment to work collaboratively with the TSX as it continues to monitor developments in this sector.

He noted that Aphria has not received notice from the TSX of a continued listing review.

Aphria has investments in Florida and Arizona.

The TMX Group, which operates the Toronto Stock Exchange, warned companies earlier this month that U.S. federal marijuana laws takes precedence over state laws.

It said that companies doing business that violates the federal law are not complying with their listing requirements.

Last week, Neufeld said he wanted to remain listed on the TSX and had no plans to move to the smaller marijuana stock-friendly Canadian Securities Exchange.

Neufeld has said that if the company cannot reach a compromise, there are options, including a spin-off of its U.S. activities to be listed on the CSE.
