I don't know about Canadian Airlines/Air Canada but I think in most airlines first officers have two or three bars on their epaulettes; four bars are for captains.

According to the article:
In August 2025, a Facebook user who said he was a former Canadian Airlines pilot claimed that U.S. President Donald Trump's plane flew to the late financier and convicted sex offender Jeffrey Epstein's island at least 37 times.
Epstein, who died in prison in 2019, owned the Great St. James and Little St. James islands, part of the U.S. Virgin Islands. Prosecutors claimed Epstein trafficked underage girls to Little St. James to conceal the abuse of his victims.
However, we found no evidence that the claim about Trump's plane flying to Little St. James was true. We could not verify that the Facebook user who made the claim actually worked for Canadian Airlines, a carrier that Air Canada acquired in 2001. Alongside the claim, the Facebook user shared a picture of himself wearing what appeared to be a pilot's costume from the online retailer Amazon.
Reporting about Little St. James found that guests accessed the island either by boat or helicopter because it didn't have an airstrip, further discrediting the claim that any of Trump or his businesses' planes would have flown to or landed there.
Trump said in January 2025 that he never visited Epstein's island.
