Hopefully any damage to plants will be minimal. I read that most trees, shrubs and perennials tolerate those wet snowfalls but not sure about annuals.

As for planting things out on the Victoria day long weekend (last weekend), I guess it's a general guideline. Some years you may be okay planting sooner, other years in early June you can get a frost. I took holidays this week to plant things in the yard but haven't got many things planting due to the rain and cool temps. Theres a risk of frost tonight, but I'll just gather my planted pots together and cover them.

Nadia, you may want to stock up on covering material for your plants which is not plastic. Plastic does not have much insulating value, although it does keep the weight of the wet snow off the plants. Fortunately this recent dump of wet snow did not include freezing temperatures.
