The evidence confirms that Michael Kovrig was detained in Beijing in December 2018 following the arrest of Meng Wanzhou, and that he was held for a long period (1,019 days). However, none of the provided evidence explicitly states that he was 'imprisoned for three years' *after* the arrest, nor does it confirm the specific duration or context of his release relative to the arrest in a way that confirms the entire claim. The duration mentioned in the search results (1,019 days) is specific but not corroborated by a second independent source confirming the 'three years' timeframe following the arrest.
