Tom sold 50 Microsoft shares on September 1, 2021 that he received a year ago as a signing bonus when he started working. He received the shares when they were valued at $300/share and recently sold them when they hit $380/share (he received a taxable benefit of $15,000 in 2020, which is the cost base of the shares when he started). All amounts are in Canadian dollars
