The Wastewater Systems Effluent Regulations (WSER), developed under the Fisheries Act, came into force in 2012 to manage wastewater releases by systems that collect an average daily influent volume of 100 cubic metres or more. The WSER also does not apply to any wastewater system located in the Northwest Territories, Nunavut and north of the 54th parallel in the provinces of Quebec and Newfoundland and Labrador. The WSER set national baseline effluent quality standards that are achievable through secondary wastewater treatment. Under the WSER, owners or operators of wastewater systems discharging annual average daily effluent volumes greater than 2,500 m3 are required to determine and report on the acute lethality of the effluent.

Approved list of the eligible air source heat pumps and cold climate heat pumps models for the Canada Greener Homes Grant. *

General notice

In response to a high level of interest in the Canada Greener Homes Grant initiative we are seeking to ensure equipment model lists used by the program are up to date and include all equipment models meeting current program criteria. Eligible model lists are scheduled for near term updates the week of November 16 2021 and last week of January 2022 respectively. The November 2021 update will be a ‘refresh’ and will add equipment models that have already qualified since the program launch in May 2021.

All available bathymetry and related information for Nipisi Lake were collected and hard copy maps digitized where necessary. The data were validated against more recent data (Shuttle Radar Topography Mission 'SRTM' imagery and Indian Remote Sensing 'IRS' imagery) and corrected where necessary. The published data set contains the lake bathymetry formatted as an Arc ascii grid. Bathymetric contours and the boundary polygon are available as shapefiles.

This data provides the integrated cadastral framework for the specified Canada Land. The cadastral framework consists of active and superseded cadastral parcel, roads, easements, administrative areas, active lines, points and annotations. The cadastral lines form the boundaries of the parcels. COGO attributes are associated to the lines and depict the adjusted framework of the cadastral fabric.

In this study, seven non‐specific biomarkers were compared in Spottail Shiners (Notropis hudsonius Clinton) from localities receiving urban and industrial effluents and relatively clean localities in the St Lawrence River, Canada. Pigmented macrophages are involved in a variety of functions including the detoxification and recycling of exogenous and endogenous material, responses to foreign material or infectious agents, and antigen recognition. Pigmented macrophage aggregates are focal accumulations of pigmented macrophages found in the spleen, kidney, liver and other organs of fishes. They may respond to toxicants or exposure to infectious agents such as viruses or bacteria either by increasing in number and size or by changing the shape of the aggregation.
