Although we had a good stretch of warm temperatures at the end of April and some more at the beginning of June, these were offset by generally cooler temperatures during the rest of the spring. In the end the daily high temperatures were about 0.5 degrees lower than average and the daily low temperatures were about 0.5 degrees higher than average, thus overall it was bang on the average.
After the very wet winter, the spring was on the low side of average coming in at 182.8 mm compared to an average of 220.9 mm. There was an 11 day stretch in April and a 7 day period in May without any precipitation, but apart from those the rest of the spring was pretty consistent.
Summary for Spring 2008:
Maximum Temperature 30.4 °C
Minimum Temperature -14.0 °C
Average Daily High Temperature 15.2 °C (Long term average 15.6 °C)
Average Daily Low Temperature 4.6 °C (Long term average 4.2 °C)
Total Precipitation 182.8 mm (Long term average 220.9 mm)
(Long term averages based on 1970-2000 data for the Waterloo Wellington Airport)

I noticed that long term average data in your summaries is from 1971-2000.
Why does this stop at 2000?
Right now the Environment Canada standard is to use the 1971-2000 period for long term averages.
It is the standard in the meteorological field to use 30 years of data to create these averages.
It is thought that this amount of time will eliminate the effects of short term fluctuations.
In general these averages are updated every 10 years so we will be a few years before the next set comes out.
