Lunitidal Interval for Toronto

I recently got a Casio watch which can tell you the different moon phases and wheather it is high or low tide during that time. The only problem is that, for all that data to be accurate I need my "Home Site" data which includes GMT Differential, Longitude and Lunitidal Interval. I have the correct data for the first two but I can't seem to find out the Lunitidal Interval. If anyone knows the Lunitidal Interval for Toronto or knows a site that has that kind of information I would greatly appriciate(sp?) it. Thank you :)

The Great Lakes don't have tides....

They do have tides...but they aren't as large as compared to ocean tides. Maybe that's the reason why they don't have a lunitidal time interval...

Well yes, there are going to some gravitational effects on the lakes, but these are not going to be easily measureable. You can expect that wave action will pretty much swamp any tidal variation. For example, after doing some digging, the spring tide turns out to be less than two inches; ordinary tide levels are significantly less. Given the preponderance of weather effects on the water levels of the lakes, they are typically classified as non-tidal bodies.
