When it came to my lifes savings, I chose to stick with my major bank's self directed brokerage which charges $9.95 to buy or sell. Therefore, the number of holdings I have increases my trading costs. Between the two of us, we also have 5 accounts, which I treat as one AA as per the link I previously provided.
As already stated, its irrelevant for someone buying through Questrade, and someone with just a single account it doesnt matter either. But even in Questrade, your dividend growth will compound quicker if your holdings are large enough to DRIP instead of cash.
My assumption about a 40+ year old who claims a mustache is that he also holds more than a TFSA and that maxing out on $5500 in January wont be his only contribution. Thus the information I linked about efficiently managing AA in multiple accounts may have been relevant.
