Summer influences of El Nino over North America are not particularly strong, especially across Manitoba and western Ontario. There is a slight warmer than average signal across coastal British Columbia though.

Take a look for yourself at this link. The quick and dirty way of reading this is that the top image is showing the anomaly (Orange above average, blue below average for temp, and green above average, brown below average for precipitation). The bottom image is how strong the signal is. Ideally, you'd want to look at the anomaly in areas where the signal is strong. You can see how the signal isn't particularly strong over Canada.
