Correct. Two months is not a trend but this quote from the NCDC is a trend:

As for Canada having unusually cool temperatures the following map of
temperature anomalies should explain it.

According to Environment Canada<>,
temperatures across Ontario were well below average, with an overall anomaly
of 2.2C (4.0F) below average. Several locations experienced their lowest
temperatures since 1992, and three locations set new low mean temperatures.
Pickle Lake set a new monthly low mean temperature for the month of July as
temperatures dropped to 14.4C (57.9F), surpassing the previous record of
14.5C (58.1F) set in 1965. Ridgetown and Elliot Lake also broke their
monthly low mean temperatures which were first set in 1891 and 1996,

Global warming does not guarantee every place on the globe is warm, just
that the dice are "loaded" for warmth. And just because it was cooler in
Canada and the Eastern U.S. did not mean that it was also cooler elsewhere.
On average, July 2009 was fifth warmest on record. But then again if you
stick one foot in boiling water and one foot in freezing water on average
you would be comfortable. :-)
