Since it has been more than 90 days since you last entered the US, and more importantly since you were only in the US for a day (and should have a passport stamp from returning to Canada that shows this), you should have no trouble returning for a holiday.
The 90-day rule you have read about is often misinterpreted. It is a rule intended to prevent visa runs to Canada and other nearby countries, so as to catch out people who are illegally trying to live in the US.
The terms of the VWP are very clear - it is only to be used for occasional, short visits to the U.S. If the CBP Officer thinks you are trying to "reset" the clock by making a short trip out of the U.S. and re-entering for another 90-day period, you can be denied entry.
Since you are a resident of Canada and have only spent one day in the US, you are obviously not trying to make a visa run and you will have little difficulty returning for another short visit.
