The report reads: "The year 1970 saw many significant changes in our Company. Sales were higher than in any previous year showing an increase in gallons of 8.8% and in dollar volume of 9.7%. The new offices and warehouse are fully operational, the fermenters installed prior to vintage assisted in holding our labour costs to a reasonable level, and the use of liquid sugar proved very successful. We added two representatives to our sales staff during the year and direct contact with our customers will be intensified. Product development is continuing and the addition of new lines and better distribution will be receiving priority. Our venture in the product supply for Valley Rouge Wines of Manitoba will, we trust, increase our sales volume and assist in lowering our fixed overhead. Capital expenses in 1971 will continue at a high level. Our co-operation with the various Government departments in respect to pollution, will obligate our Company to install facilities to satisfy the strict requirements in this regard. Preparations must be made now to handle bulk harvested grapes, the addition of storage and fermenting capacity and the replacement of production equipment, will be under constant review, thus enabling us to maintain production and efficiency. With the continued dedicated service of our personnel and the support of all our Shareholders, we are confident the challenge will be met in 1971."

Several automated reversed-phase HPLC methods have been developed to determine trace concentrations of carbamate pesticides (which are of concern in Ontario environmental samples) in water by utilizing two solid sorbent extraction techniques. One of the methods is known as on-line pre-concentration'. This technique involves passing 100 milliliters of sample water through a 3 cm pre-column, packed with 5 micron ODS sorbent, at flow rates varying from 5-10 mUmin. By the use of a valve apparatus, the HPLC system is then switched to a gradient mobile phase program consisting of acetonitrile and water. The analytes, Propoxur, Carbofuran, Carbaryl, Propham, Captan, Chloropropham, Barban, and Butylate, which are pre-concentrated on the pre-column, are eluted and separated on a 25 cm C-8 analytical column and determined by UV absorption at 220 nm. The total analytical time is 60 minutes, and the pre-column can be used repeatedly for the analysis of as many as thirty samples. The method is highly sensitive as 100 percent of the analytes present in the sample can be injected into the HPLC. No breakthrough of any of the analytes was observed and the minimum detectable concentrations range from 10 to 480 ng/L. The developed method is totally automated for the analysis of one sample. When the above mobile phase is modified with a buffer solution, Aminocarb, Benomyl, and its degradation product, MBC, can also be detected along with the above pesticides with baseline resolution for all of the analytes. The method can also be easily modified to determine Benomyl and MBC both as solute and as particulate matter. By using a commercially available solid phase extraction cartridge, in lieu of a pre-column, for the extraction and concentration of analytes, a completely automated method has been developed with the aid of the Waters Millilab Workstation. Sample water is loaded at 10 mL/min through a cartridge and the concentrated analytes are eluted from the sorbent with acetonitrile. The resulting eluate is blown-down under nitrogen, made up to volume with water, and injected into the HPLC. The total analytical time is 90 minutes. Fifty percent of the analytes present in the sample can be injected into the HPLC, and recoveries for the above eight pesticides ranged from 84 to 93 percent. The minimum detectable concentrations range from 20 to 960 ng/L. The developed method is totally automated for the analysis of up to thirty consecutive samples. The method has proven to be applicable to both purer water samples as well as untreated lake water samples.

The notion of citizenship, while a basic human right, has come under scrutiny. It was once assumed a liberal inspired regime of citizenship rights would reign as the primary ideological perspective in the Western world, however this has not been the case. Numerous competing paradigms have questioned the premise upon which liberal guarantees of citizenship rights are based. In particular, communitarianism has subjected liberal rights discourse to a closer examination. Communitarian theory holds that universalist principles negate any articulation of community and its internal diversity, such as cultural citizenship. It is this understanding of citizenship that has taken hold in Canada. The Canadian political experience illustrates a number of attributes associated with communitarian thought. It is a collectivist society that articulates a notion of the common good, acknowledges the internal diversity of its citizens and possesses a highly developed deliberative democratic process. To this end, Canada can be described as being more communitarian than liberal in nature in the process it has adopted to address citizenship rights. However, the type of commuIiitarianism displayed in Canada differs from the political models examined by such scholars as Michael Sandel, Iris Marion Young or Will Kymlicka. Cultural citizenship rights are fluid and malleable in Canada. While no clear guarantees of citizenship rights exist, there is a common commitment by Canadians to engage in a fair, open and inclusive deliberative process. This model is unique to Canada; it cannot be exported in that it is a product of Canadian political culture. As a result, the contemporary demands of cultural citizenship are dealt with effectively and democratically in Canada in that the proper mechanisms for public deliberation exist.
