What the VO checks for your Bank statement is takes the balance of each month for the last 6 months and calculates the average (mean) balance for the last 6 months. If that matches or is greater than the LICO for a family of 3 then VO passes it else fails. (a few C$100 +/- is not a big deal though)
So please check if you pass that calculation test, if yes you are good to go...and ofcourse when the VO sees a regular salary credit of similar value that surely helps (am sure VOs are humans too, and don't just rely of math alone
)
Hope that helps!
