CBC has a timeline of what they know:

I think they are still trying to determine where he was between when the police arrived to find the first shooting victims at his home and the nearby house fires at 11:30 pm last night and when he was first sighted the next morning. They also don't mention the police cars that were crashed/burned near Shubenacadie around 11 am which seems to be part of this.
I because they don't know where he was, the police were still trying to determine if there were more crime scenes than the ones they have already found. It's a rural area with lots of small roads and little villages and he seems to have avoided the main highway. If we weren't locked down due to COVID , some of the areas he went to - like the Irving Big Stop where he died - would have been very crowded on a Sunday morning.
Starting to see facebook posts from families and friends of the victims :-( So sad.
