In particular, it sounds like the ABPC and ABQB will continue to hear EPOs, some urgent Apprehension Orders and initial custody hearings under s 21.1 of CYFEA in ABPC, and some urgent Family Court matters (the examples of absconding with a child or risk of removal of a child from the jurisdiction are given). ABQB can still also address restraining orders and preservation orders, and it looks like they may give second priority to "Urgent orders relating to parenting time, contact or communication with a child (that cannot reasonably be delayed)". See the above appendices for the complete lists. That means that some urgent parenting disputes might still be on the table.
The ABPC has also updated their Covid planning page, including a reduction of courthouses and separate pages with additional information for Edmonton, Calgary, and outside of those centres: https://albertacourts.ca/pc/resources/covid
