I wonder what caused the discrepancy?

Statistics Canada does regular revisions to population estimates, and usually many of those adjustments occur after a census has been released to account for new information. This is because the data are just that, estimates.
For example, during the pandemic Manitoba's Vital Statistics agency had a massive backlog so the total amount of births and deaths being recorded was out of date most of the time. But at some point, StatCan needs to obtain that information from Manitoba Vital Stats even if it isn't accurate (due to the backlog). So when StatCan publishes the population numbers of Manitoba for 2021, they may be inaccurate due to them receiving inaccurate statistics from Vital Stats. Then, later in the year once Vital Stats catches up, StatCan will add the revised info the next time they update the national/provincial population numbers which only happens once per year, usually in February. You can often find this type information spread across the various footnotes in the StatCan data tables.
Population estimates rely on a variety of provincial agencies outside the Federal Government to accurately calculate all the various components of population change (births, deaths, immigration, international post-secondary students, etc.), and things may not always be accurate or 100% complete by the time StatCan requests the info. That, combined with census data being updated every 5 years, can lead to historical population estimate revisions.
Also, I'm always surprised how much stock this forum and the national forum put in the population clock. I would never use the population clock numbers for any models or formal work because they are just representative. StatCan doesn't actually know how many immigrations arrive in BC on April 4 at 10:35 AM. They likely just take a look at aggregate numbers over the past few quarters and distribute them evenly over the next quarter while adjusting for seasonal effects. It's not really indicative of what's actually happening since it is just taking historical trends and projecting them forward. It's better than nothing obviously, but quarterly population estimates will always be the best number to look at, and will always supersede the accuracy of the population clock. The population clock is just for fun IMO.
