01 · Start from your real room
Enter your CRA figure, or estimate it
Room tracking lives in the Analytics section, on the Contribution Room tab, and it covers TFSA and FHSA accounts. You set your starting room one of three ways. The most accurate is to type the number straight from CRA My Account or your latest Notice of Assessment, with the date it was current, which Mozaic then treats as authoritative. If you do not have that handy, estimate it from your birth year, adding a residency year if you became a Canadian resident after 2009, and Mozaic adds up the published annual limits from the first year you were eligible. The third option is to enter your total net deposit to date.
The CRA path wins on accuracy for a simple reason: only the CRA knows the room you carried into the app, before any of your accounts were connected. If you have never over-contributed and you have been eligible since 2009, the standalone TFSA contribution room calculator is a quick way to get that starting figure without signing in.
02 · Room that moves with your accounts
Contributions counted, transfers left out
Once your room is set, Mozaic watches the inflows to your registered accounts and counts them as contributions. Not every deposit uses room, so each one is yours to review: a transfer in from another TFSA does not count against your limit, and you switch it off in the review sheet so the running total stays accurate. You can also add contributions Mozaic cannot see, like a deposit made before your account was connected.

03 · Why it is an estimate
Straight about what a tracker can and cannot know
Every figure Mozaic shows here is a planning estimate, not tax advice, and the app repeats that on every room view. Two things keep a tracker from being the last word. Mozaic can only see contributions made after your accounts synced, so anything from before that window has to be entered by hand or captured by your CRA starting figure. And TFSA withdrawals free up room on January 1 of the next year, not the day you withdraw, so mid-year the running number can sit slightly apart from the CRA's.
That is why the CRA figure you enter is the anchor and everything else adjusts around it. Use the tracker to stay on top of your room through the year and to avoid the obvious mistakes. When you are about to make a large contribution, confirm the exact number in CRA My Account first. The CRA is the official source for your contribution room, and Mozaic is built to agree with it, not to replace it.
04 · Before the over-contribution
A warning is worth more than a penalty
The whole point of tracking room is the moment before you cross it. When your contributions approach or pass your limit, Mozaic flags it and reminds you that the CRA charges 1% per month on the highest excess amount for each month it sits in the account. A recontribution of an amount you withdrew earlier in the same year is the classic trap, because the room does not come back until January, and it is exactly what the warning is there to catch.
Your TFSA also sits inside the bigger picture. The same accounts feed your net worth, your investment holdings, and your cash flow, so the room tracker is one view among several rather than a standalone calculator you check once a year and forget.
