The Saskatoon-based uranium miner estimates it will take about two years for the Federal Court of Appeal to hear and decide the case.
“We are disappointed that the CRA has taken this action after such a clear and decisive ruling from the Tax Court,” said Tim Gitzel, Cameco’s president and CEO, in a statement.
“We will continue through the appeal process and expect the appeal to be decided in our favour as well.”
Last month, Cameco said the Tax Court ruled its favour in the case which centred around its use of a subsidiary in Switzerland to sell and trade its uranium.
The CRA contended it was a sham established to avoid Canadian taxes, while Cameco maintained it was for legal and sound business practices.
Despite the CRA appeal, Cameco said it will be making an application to the court to recover costs incurred over the course of this case.
Cameco noted that decisions of the Federal Court of Appeal may be appealed to the Supreme Court of Canada, if the top court agrees to hear the appeal.
