AC did offer this guidance in it's earnings report earlier this week..............

"Air Canada has reduced second quarter 2020 capacity by 85 to 90 per cent when compared to 2019’s second quarter. Third quarter 2020 capacity is expected to be reduced by approximately 75 per cent when compared to the third quarter of 2019. The airline will continue to dynamically adjust capacity and take other measures as required to account for health warnings, travel restrictions, border closures globally and passenger demand."

I don't imagine YYZ-TLV would be a high enough priority to be some of the 10% of flying it's doing in Q2.
There may be a gap at the end of Q3, between covid and flu seasons, where there is some profitable demand to operate to TLV.
